C#WinForm窗体事件执行次序

一、以下是网络上可搜索到的次序

当 Windows Form 应用程序启动时，会以下列顺序引发主要表单的启动事件：
System.Windows.Forms.Control.HandleCreated
System.Windows.Forms.Control.BindingContextChanged
System.Windows.Forms.Form.Load
System.Windows.Forms.Control.VisibleChanged
System.Windows.Forms.Form.Activated
System.Windows.Forms.Form.Shown

当应用程序关闭时，会以下列顺序引发主要表单的关闭事件：
System.Windows.Forms.Form.Closing
System.Windows.Forms.Form.FormClosing
System.Windows.Forms.Form.Closed
System.Windows.Forms.Form.FormClosed
System.Windows.Forms.Form.Deactivate

二、以下是我测试的次序，全部protected override 这些事件，并且在其base.的前后分别处理一次，如下

protectedoverridevoidOnLoad(EventArgse)
{
textBox1.Text+="OnLoad1"+"/r/n";
base.OnLoad(e);
textBox1.Text+="OnLoad2"+"/r/n";
}

        protected override void OnLoad(EventArgs e)
        {
            textBox1.Text += "OnLoad1" + "/r/n";
            base.OnLoad(e);
            textBox1.Text += "OnLoad2" + "/r/n";
        }

OnClientSizeChanged1
OnClientSizeChanged2
OnClientSizeChanged1
OnClientSizeChanged2

// Loyout要多次执行
OnLayout1
OnLayout2
OnHanleCreated1
OnHanleCreated2
OnInvalidated1
OnInvalidated2

// 注意这里的一点点变化
OnCreateControl1
OnLoad1
OnLoad2
OnCreateControl2

//
OnLayout1
OnLayout2
OnActivated1
OnActivated2
OnShown1
OnShown2
OnPain1
OnPain2

希望这个次序能给大家带来用处。。可以在不同事件中去处理所需要的代码

三、以下是代码源。C# 2008 Express

usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
//usingSystem.Linq;
usingSystem.Text;
usingSystem.Windows.Forms;

namespaceWindowsFormsApplication1
{
publicpartialclassForm1:Form
{
publicForm1()
{
InitializeComponent();
}

//输出窗体事件的执行次序

protectedoverridevoidOnActivated(EventArgse)
{
textBox1.Text+="OnActivated1"+"/r/n";
base.OnActivated(e);
textBox1.Text+="OnActivated2"+"/r/n";
}

protectedoverridevoidOnClientSizeChanged(EventArgse)
{
textBox1.Text+="OnClientSizeChanged1"+"/r/n";
base.OnClientSizeChanged(e);
textBox1.Text+="OnClientSizeChanged2"+"/r/n";
}

protectedoverridevoidOnCreateControl()
{
textBox1.Text+="OnCreateControl1"+"/r/n";
base.OnCreateControl();
textBox1.Text+="OnCreateControl2"+"/r/n";
}

protectedoverridevoidOnDeactivate(EventArgse)
{
textBox1.Text+="OnDeactivate1"+"/r/n";
base.OnDeactivate(e);
textBox1.Text+="OnDeactivate2"+"/r/n";
}

protectedoverridevoidOnHandleCreated(EventArgse)
{
textBox1.Text+="OnHanleCreated1"+"/r/n";
base.OnHandleCreated(e);
textBox1.Text+="OnHanleCreated2"+"/r/n";
}

protectedoverridevoidOnHandleDestroyed(EventArgse)
{
textBox1.Text+="OnHanleDestoryed1"+"/r/n";
base.OnHandleDestroyed(e);
textBox1.Text+="OnHanleDestoryed2"+"/r/n";
}

protectedoverridevoidOnInvalidated(InvalidateEventArgse)
{
textBox1.Text+="OnInvalidated1"+"/r/n";
base.OnInvalidated(e);
textBox1.Text+="OnInvalidated2"+"/r/n";
}

protectedoverridevoidOnLayout(LayoutEventArgslevent)
{
textBox1.Text+="OnLayout1"+"/r/n";
base.OnLayout(levent);
textBox1.Text+="OnLayout2"+"/r/n";
}

protectedoverridevoidOnLoad(EventArgse)
{
textBox1.Text+="OnLoad1"+"/r/n";
base.OnLoad(e);
textBox1.Text+="OnLoad2"+"/r/n";
}

protectedoverridevoidOnPaint(PaintEventArgse)
{
textBox1.Text+="OnPain1"+"/r/n";
base.OnPaint(e);
textBox1.Text+="OnPain2"+"/r/n";
}

protectedoverridevoidOnShown(EventArgse)
{
textBox1.Text+="OnShown1"+"/r/n";
base.OnShown(e);
textBox1.Text+="OnShown2"+"/r/n";
}


}
