         开发一个Windows Live Writer插件，在写博客时，添加自己的代码样式。最终效果是，在Windows Live Writer中选中代码，然后点击插件，将代码包含在<div class="mycode">your code</div>中。当然要在最终发表的博客上添加.mycode 的CSS样式才有效果。

        .mycode样式如下:

.mycode {
    margin: 10px;
    padding: 10px;
    background: #DDEDFB;
    border: 1px solid #428EDE; 
    text-align: left;
    /*width:500px;*/
    overflow-x:auto;
    font-size:20px;
    white-space:nowrap;
    *white-space: normal;
    WORD-WRAP: break-word;/*IE*/
    word-break:break-all;/*IE*/
}

选中代码，点击"WintyCodeArea":

效果如下图

(在Writer需启用"使用主题编辑"，并已从博客中获取主题，才能立即看到效果):

0、准备工作

• 在Visual Studio 2008中新建C#"Class Library"项目
• 在项目中添加References:"C:\Program Files\Windows Live\Writer\WindowsLive.Writer.Api.dll"
• 在项目属性的"Build Events"=>"Post Build Event command line"添加:(XCOPY /D /Y /R "$(TargetPath)" "C:\Program Files\Windows Live\Writer\Plugins")

 

1、"Class Library"主类，继承于ContentSource

WintyCodeArea.cs:

using System.Windows.Forms;
using WindowsLive.Writer.Api;

/*

http://www.blogjava.net/wintys
  */
namespace MyWindowsLiveWriterPlugin
{
    /*Plugin 主类*/
    [WriterPlugin("{7DFB5431-D7DA-4e61-9E4B-056D30DFDB63}",
        "WintyCodeArea",
        PublisherUrl = "http://www.blogjava.net/wintys" ,
        ImagePath = "image.jpg",
        HasEditableOptions = true,
        Description = "Insert <div class=\"mycode\">your code</div>\nhttp://www.blogjava.net/wintys\[e-mail]")]
    [InsertableContentSource("WintyCodeArea")]
    public class WintyCodeArea : ContentSource
    {
        WintyCodeAreaSettings m_settings;

        public override void Initialize(IProperties pluginOptions)
        {
            base.Initialize(pluginOptions);
            m_settings = new WintyCodeAreaSettings(pluginOptions);
        }
        public override DialogResult CreateContent(IWin32Window dialogOwner, ref string content)
        {
            string originalContent = content;

            content = m_settings.FrontCode;
            if(m_settings.EscapeCode)
                content +=  System.Web.HttpUtility.HtmlEncode(originalContent);
            else
                content += originalContent;
            content += m_settings.BackCode;

            return DialogResult.OK;
        }

        public override void EditOptions(IWin32Window dialogOwner)
        {
            SettingForm settingForm = new SettingForm(m_settings);
            settingForm.ShowDialog(dialogOwner);
        }
    }
}

 

         Initialize()、EditOptions()并不是必须的，这里因为用到了"设置选项"窗口，才需要。

CreateContent(IWin32Window dialogOwner, ref string content)在此为必须，content传入值为Live Writer当前被选中的高亮区的HTML代码 ，无论在编辑还是在源代码视图中都是这样的。content的传出值为你修改后的HTML代码，最终将在Live Writer中显示的。

        在CreateContent()中也可以弹出窗体，此处并未用到。以下是代码示例:

public override DialogResult CreateContent(IWin32Window dialogOwner, ref string content)
{
    using (InsertCodeForm insertCodeForm = new InsertCodeForm())
    {
        DialogResult result = insertCodeForm.ShowDialog();
        content = insertCodeForm.MyCode;
        return result;
    }
}

        相应的InsertCodeForm类的部分代码如下:

public partial class InsertCodeForm : Form
{
    private string m_MyCode;
    public string MyCode
    {
        get { return m_MyCode; }
        set { m_MyCode = value; }
    }

    public InsertCodeForm()
    {
        InitializeComponent();
    }

    private void buttonInsert_Click(object sender, EventArgs e)
    {
        if (textBoxCode.Text == string.Empty)
        {
            return;
        }

        m_MyCode = "<div class=\"mycode\">";
        m_MyCode += System.Web.HttpUtility.HtmlEncode(textBoxCode.Text);
        m_MyCode += "</div>";           

        this.DialogResult = DialogResult.OK;
    }
}

 

2、用于设置WintyCodeArea插件行为的类

WintyCodeAreaSettings.cs:

using WindowsLive.Writer.Api;

namespace MyWindowsLiveWriterPlugin
{
    class WintyCodeAreaSettings
    {
        IProperties m_properties;

        private const string FRONT_CODE = "FRONT_CODE";//前缀代码
        private const string BACK_CODE = "BACK_CODE";//后缀代码
        private const string ESCAPE_CODE = "ESCAPE_CODE";//是否转义代码

        public const string DEFAULT_FRONT_CODE = "<div class=\"mycode\">";
        public const string DEFAULT_BACK_CODE = "</div>";
        public const bool   DEFAULT_ESCAPE_CODE = false;

        public WintyCodeAreaSettings(IProperties properties)
        {
            m_properties = properties;
        }

        public string FrontCode
        {
            get
            {
                return m_properties.GetString(FRONT_CODE, DEFAULT_FRONT_CODE);
            }
            set
            {
                m_properties.SetString(FRONT_CODE, value);
            }
        }

        public string BackCode
        {
            get
            {
                return m_properties.GetString(BACK_CODE, DEFAULT_BACK_CODE);
            }
            set
            {
                m_properties.SetString(BACK_CODE, value);
            }
        }

        public bool EscapeCode
        {
            get
            {
                return m_properties.GetBoolean(ESCAPE_CODE, DEFAULT_ESCAPE_CODE);
            }
            set
            {
                m_properties.SetBoolean(ESCAPE_CODE, value);
            }
        }

    }
}

 

3、"设置窗口"的代码

        点击"工具=>选项"就可以找到这个设置窗口。

 

        WintyCodeArea的设置窗口:

 

        所谓的转义原始内容，就是将所选内容中的特殊HTML字符进行编码(空格与换行不变)。

 

SettingForm.cs:

using System;
using System.Windows.Forms;

namespace MyWindowsLiveWriterPlugin
{
    partial class SettingForm : Form
    {
        WintyCodeAreaSettings m_settings;

        public SettingForm(WintyCodeAreaSettings settings)
        {
            InitializeComponent();
            //Winty's initialization
            m_settings = settings;
            txtFrontCode.Text = m_settings.FrontCode;
            chkEscapeCode.Checked = m_settings.EscapeCode;
            textBackCode.Text = m_settings.BackCode;
        }

        /*保存设置*/
        private void btnOK_Click(object sender, EventArgs e)
        {
            m_settings.FrontCode = txtFrontCode.Text;
            m_settings.EscapeCode = chkEscapeCode.Checked;
            m_settings.BackCode = textBackCode.Text;

            Close();
        }

        /*恢复默认设置*/
        private void btnRestoreDefault_Click(object sender, EventArgs e)
        {
            m_settings.FrontCode = WintyCodeAreaSettings.DEFAULT_FRONT_CODE;
            m_settings.EscapeCode = WintyCodeAreaSettings.DEFAULT_ESCAPE_CODE;
            m_settings.BackCode = WintyCodeAreaSettings.DEFAULT_BACK_CODE;

            txtFrontCode.Text = m_settings.FrontCode;
            chkEscapeCode.Checked = m_settings.EscapeCode;
            textBackCode.Text = m_settings.BackCode;
        }
    }
}

 

SettingForm.Designer.cs(这是Visual Studio根据设计的窗体生成的代码):

namespace MyWindowsLiveWriterPlugin
{
    partial class SettingForm
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.btnOK = new System.Windows.Forms.Button();
            this.chkEscapeCode = new System.Windows.Forms.CheckBox();
            this.labelFont = new System.Windows.Forms.Label();
            this.labelBack = new System.Windows.Forms.Label();
            this.txtFrontCode = new System.Windows.Forms.TextBox();
            this.textBackCode = new System.Windows.Forms.TextBox();
            this.btnRestoreDefault = new System.Windows.Forms.Button();
            this.SuspendLayout();
            //
            // btnOK
            //
            this.btnOK.Location = new System.Drawing.Point(222, 211);
            this.btnOK.Name = "btnOK";
            this.btnOK.Size = new System.Drawing.Size(113, 29);
            this.btnOK.TabIndex = 0;
            this.btnOK.Text = "设置";
            this.btnOK.UseVisualStyleBackColor = true;
            this.btnOK.Click += new System.EventHandler(this.btnOK_Click);
            //
            // chkEscapeCode
            //
            this.chkEscapeCode.AutoSize = true;
            this.chkEscapeCode.Location = new System.Drawing.Point(127, 94);
            this.chkEscapeCode.Name = "chkEscapeCode";
            this.chkEscapeCode.Size = new System.Drawing.Size(96, 16);
            this.chkEscapeCode.TabIndex = 1;
            this.chkEscapeCode.Text = "转义原始内容";
            this.chkEscapeCode.UseVisualStyleBackColor = true;
            //
            // labelFont
            //
            this.labelFont.AutoSize = true;
            this.labelFont.Location = new System.Drawing.Point(48, 12);
            this.labelFont.Name = "labelFont";
            this.labelFont.Size = new System.Drawing.Size(53, 12);
            this.labelFont.TabIndex = 2;
            this.labelFont.Text = "前缀代码";
            //
            // labelBack
            //
            this.labelBack.AutoSize = true;
            this.labelBack.Location = new System.Drawing.Point(48, 125);
            this.labelBack.Name = "labelBack";
            this.labelBack.Size = new System.Drawing.Size(53, 12);
            this.labelBack.TabIndex = 4;
            this.labelBack.Text = "后缀代码";
            //
            // txtFrontCode
            //
            this.txtFrontCode.Location = new System.Drawing.Point(125, 12);
            this.txtFrontCode.Multiline = true;
            this.txtFrontCode.Name = "txtFrontCode";
            this.txtFrontCode.Size = new System.Drawing.Size(247, 64);
            this.txtFrontCode.TabIndex = 5;
            //
            // textBackCode
            //
            this.textBackCode.Location = new System.Drawing.Point(125, 125);
            this.textBackCode.Multiline = true;
            this.textBackCode.Name = "textBackCode";
            this.textBackCode.Size = new System.Drawing.Size(247, 64);
            this.textBackCode.TabIndex = 6;
            //
            // btnRestoreDefault
            //
            this.btnRestoreDefault.Location = new System.Drawing.Point(88, 211);
            this.btnRestoreDefault.Name = "btnRestoreDefault";
            this.btnRestoreDefault.Size = new System.Drawing.Size(106, 29);
            this.btnRestoreDefault.TabIndex = 7;
            this.btnRestoreDefault.Text = "恢复默认设置";
            this.btnRestoreDefault.UseVisualStyleBackColor = true;
            this.btnRestoreDefault.Click += new System.EventHandler(this.btnRestoreDefault_Click);
            //
            // SettingForm
            //
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(420, 252);
            this.Controls.Add(this.btnRestoreDefault);
            this.Controls.Add(this.textBackCode);
            this.Controls.Add(this.txtFrontCode);
            this.Controls.Add(this.labelBack);
            this.Controls.Add(this.labelFont);
            this.Controls.Add(this.chkEscapeCode);
            this.Controls.Add(this.btnOK);
            this.Name = "SettingForm";
            this.Text = "WintyCodeArea Settings";
            this.ResumeLayout(false);
            this.PerformLayout();

        }

        #endregion

        private System.Windows.Forms.Button btnOK;
        private System.Windows.Forms.CheckBox chkEscapeCode;
        private System.Windows.Forms.Label labelFont;
        private System.Windows.Forms.Label labelBack;
        private System.Windows.Forms.TextBox txtFrontCode;
        private System.Windows.Forms.TextBox textBackCode;
        private System.Windows.Forms.Button btnRestoreDefault;
    }
}

 

4、总结

        工程最终生成WintyCodeArea.dll，将其复制到"C:\Program Files\Windows Live\Writer\Plugins"目录，启动Windows Live Writer就可以使用这个插件了。或将其做成WintyCodeAreaWLWPluginSetup.msi(见附件)，点安装即可(msi制作方法参考[11])。

       此插件主要供自己使用，其他人可能不会想要我的这种效果，所以暂命名WintyCodeArea。但是除了添加<div class="mycode">your code</div>外，还可以进行代码转义设置，并且前后缀代码都可以自定义，根据需要自己添加前缀后缀代码就行了，所以，希望对别人有点用处。

 

补充:

      如果插件需要访问剪贴板，可参考如下代码:

//System.Windows.Forms.Clipboard

IDataObject iData = Clipboard.GetDataObject();
if (iData.GetDataPresent(DataFormats.Text))
{
    str = (String)iData.GetData(DataFormats.Text);
    ......
}
