首先把FredCK.FCKeditorV2.dll添加到引用
具体方法如下，一个是客户端版本，一个是服务器端版本
客户端版本：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="CaseTemplate_ADD.aspx.cs" Inherits="MyProject.CaseTemplate_ADD" %>

</body>
</html>
服务器端
先在配置文件里配置好，再把资源包放项目里
<appSettings>
<add key="FCKeditor:BasePath" value="~/kfckeditor/"/>
<add key="FCKeditor:UserFilesPath" value="~/Files/"/>
</appSettings>
代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Test02.aspx.cs" Inherits="MyProject.Test02" %>
<%@ Register Assembly="FredCK.FCKeditorV2" Namespace="FredCK.FCKeditorV2" TagPrefix="FCKeditorV2" %>
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/><title></title>
</head>
<body><form id="form1"><div>0000<FCKeditorV2:FCKeditor ID="FCKeditor1" runat="server" Height="480px"></FCKeditorV2:FCKeditor></div></form>
</body>
</html>
取值后台用FCKeditor1.value就可以了，提交按钮必须要加runat="server"
