所以就为FCKeditor写了个InsertCode的插件。整个插件的制作过程非常简单：
FCKeditor插件开发请参考FCKeditor官网的文档：

http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/Customization/Plug-ins
首先，我们在FCKeditor/editor/plugins目录下新建一个insertcode目录，并在insertcode目录下新建一个fckplugin.js文件。
在新建的fckplugin.js文件中插入下面的代码：
//插入代码

复制代码代码如下:

FCKCommands.RegisterCommand('InsertCode', new FCKDialogCommand('InsertCode', FCKLang.InsertCode, FCKPlugins.Items['insertcode'].Path + 'insertcode.aspx', 700, 600)) ; 
var insertcodeItem = new FCKToolbarButton('InsertCode', FCKLang['InsertCode']) ; 
insertcodeItem.IconPath = FCKPlugins.Items['insertcode'].Path + 'images/insertcode.gif'; 
FCKToolbarItems.RegisterItem('InsertCode', insertcodeItem); 

在FCKeditor/editor/plugins/insertcode目录下创建images，lang，languages目录，在lang目录下新建en.js,zh-cn.js。en.js的内容为：
FCKLang.InsertCode = 'Insert Codes' ;
zh-cn.js的内容为：
FCKLang.InsertCode = '插入代码' ;
下载CodeHighlighter https://www.ogeek.net/codes/94.html
控件并解压，把CodeHighlighter/bin目录下的ActiproSoftware.CodeHighlighter.Net20.dll,ActiproSoftware.Shared.Net20.dll,CodeHighlighterTest.dll三个DLL复制到BlogEngine.Web/bin目录，
将CodeHighlighter/Languages里的Lexers整个目录复制到FCKeditor/editor/plugins/insertcode/languages目录，
将CodeHighlighter/Images/OutliningIndicators/目录下的所有图片复制到FCKeditor/editor/plugins/insertcode/images目录，并将这个图片下载保存到FCKeditor/editor/plugins/insertcode/images/insertcode.gif。

在FCKeditor/editor/plugins/insertcode/目录下新建insertcode.aspx，注意，如果是用Visual Studio新建的话

insertcode.aspx内容如下：

复制代码代码如下:

<%@ Page Language="C#" ValidateRequest="false" %> 

<%@ Register TagPrefix="CH" Namespace="ActiproSoftware.CodeHighlighter" Assembly="ActiproSoftware.CodeHighlighter.Net20" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 

<script runat="server"> 
static string code = string.Empty; 

protected void btnSubmit_Click(object sender, EventArgs e) 
...{ 
code = txtCode.Text; 
Highlighter.LanguageKey = ddlLangType.SelectedItem.Text; 
Highlighter.OutliningEnabled = chkOutLining.Checked; 
Highlighter.LineNumberMarginVisible = chkLineNum.Checked; 
Highlighter.Text = code; 
} 
protected void Page_Load(object sender, EventArgs e) 
...{ 
if (!Page.IsPostBack) 
...{ 
CodeHighlighterConfiguration config = (CodeHighlighterConfiguration)ConfigurationManager.GetSection("codeHighlighter"); 
string[] keys = new string[config.LanguageConfigs.Keys.Count]; 
config.LanguageConfigs.Keys.CopyTo(keys, 0); 
Array.Sort(keys); 
foreach (string key in keys) 
...{ 
ddlLangType.Items.Add(key); 
} 
ddlLangType.SelectedIndex = ddlLangType.Items.IndexOf(ddlLangType.Items.FindByText("C#")); 
} 
} 

protected void CodeHighlighter_PostRender(object sender, EventArgs e) 
...{ 
if (!string.IsNullOrEmpty(Highlighter.Output)) 
...{ 
lblCode.Text = Highlighter.Output.Replace(" ", "&nbsp;&nbsp;").Replace("\n", "<br />"); 
Response.Write("<scr" + "ipt>window.parent.SetOkButton( true );</scr" + "ipt>"); 
} 
} 
</script> 

<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server">

<script src="http://www.cnblogs.com/dialog/common/fck_dialog_common.js" type="text/javascript"></script> 

<script type="text/javascript"> 

var oEditor = window.parent.InnerDialogLoaded() ; 

// Gets the document DOM 
var oDOM = oEditor.FCK.EditorDocument ; 

var oActiveEl = oEditor.FCKSelection.GetSelectedElement() ; 

window.onload = function() 
...{ 
//window.parent.SetOkButton( false ); 
} 

function Ok() 
...{ 
if(GetE('txtCode').value == '') 
...{ 
alert("代码内容不能为空！"); 
return false; 
} 
oEditor.FCK.InsertHtml(document.getElementById("lblCode").innerHTML) ; 
return true ; 
} 

</script> 

<style type="text/css"> 
.langType 
...{

.btnRun 
...{ 
padding-top: 5px;

</head> 
<body> 
<form id="form1" runat="server">

<div class="langType">

</pre> 
<asp:Label ID="lblCode" Style="display: none;" runat="server"></asp:Label> 
</div> 
</div> 
</form> 
</body> 
</html>

接下来修改FCKeditor/fckconfig.js，在原文件中我们能找到// FCKConfig.Plugins.Add( 'autogrow' ) ;这段代码，在这段代码下一行插入：FCKConfig.Plugins.Add( 'insertcode' , 'zh-cn,en' ) ;

最后修改Web.config文件：（请参考CodeHighlighter/Web.config）
在<configuration>里插入：
<configSections>
<section name="codeHighlighter" requirePermission="false" type="ActiproSoftware.CodeHighlighter.CodeHighlighterConfigurationSectionHandler, ActiproSoftware.CodeHighlighter.Net20" />
</configSections>

在<system.web></system.web>后插入：
<codeHighlighter>
<cache languageTimeout="3" />
<keywordLinking enabled="true" target="_blank" defaultKeywordCollectionKey="ActiproKeywords">
<keywordCollection key="ActiproKeywords">
<explicitKeyword tokenKey="IdentifierToken" patternValue="Actipro" url="http://www.actiprosoftware.com" caseSensitive="false" />
<explicitKeyword tokenKey="IdentifierToken" patternValue="CodeHighlighter" url="http://www.codehighlighter.com" caseSensitive="false" />
</keywordCollection>
</keywordLinking>

这次的插件就完工了。这种方法可以说是一劳永逸，以后更换高版本的FCKeditor时，只需要修改fckconfig.js将这个插件加入就可以了
