先在网上找到附件中的素材和部分源码，在稍加改造即可应用于评论框或者留言框旁边

 

 

下面代码和网上下载的素材是不一样的，素材中的是html控件，而下面则改成了服务器控件（为了能在后台获取文本框的值），先上代码，改动说明下面再说：

原素材是获取name，而服务器控件没有name，故我们改成获取id

即将onClick="document.forms[0].gb_word.value（这句看不懂没有关系，是素材中的）改成

onClick="document.getElementById('txtname').value

注：txtname为文本框的id值

 

这样就能在.cs文件中能取得文本框的值，从而添加到数据库中

 

注：服务器控件的id转成html的id后是一段很长的字符串，如果上面改动不能用，就把txtname改成对应生成的html页面的id即可

 

到此为止，展示页面的代码就改完了，接下来在后面进行处理，主要用到了replace（用法在网上搜一下就知道了，非常好用的）函数。

 

符号装成图片的方法

 public string PictureSwap(string str)
    {
        string[] a = new string[] { "[-_-]", "[@o@]", "[-|-]", "[o_o]", "[ToT]", "[*_*]", "[-x-]", "[-_-zz]", "[t_t]", "[-_-!]", "[:,]", "[:P]", "[:D]", "[:)]", "[:(]", "[:O]", "[:#]", "[:Z]", "[:0=]", "[/:P]", "[:$]", "[-.-]", "[/-_-]", "[:{]", "[zz]", "[|-_-|]", "[-_-||]", "[:.]", "[:-Q]", "[9_9]", "[:,.]", "[:?]", "[:-|]", "[:K]", "[:G]", "[:L]", "[:c]", "[:q]", "[:Y]", "[/gs]", "[/sg]", "[/hp]", "[/ok]", "[/rain]", "[/yin]" };
        for (int i = 1; i <= 45; i++)
        {
            str = str.Replace(a[i - 1], "<img src='../images/" + i + ".gif' width='20' height='20'/>");
           
        }
        Response.Write(str + "asadadadad<br/>");
        return str;
    }

 参数str为要要转换的文字，比如说是整个留言的内容（其中加有类似（[-|-]）的符号）

 

用到了数组跟循环，也不太难就不说了

 

调用方法

string s = PictureSwap(txtname.Text.toString());
 

s即为转换后的能显示图片的字符串

 

显示时有两种处理方式：

1.在存入数据库之前调用PictureSwap改变成图片地址

2、取出数据时调用PictureSwap转换成图片显示

 

这就看个人爱好，也看是哪一个使用频繁咯。
