主要步骤：
1、解压文件后，将fckeditor文件夹拷贝到根目录下，然后添加引用，浏览到dll文件夹中对应的dll即可。
2、添加fckeditor的注册及引入控件，如下
<%@ Register Assembly="FredCK.FCKeditorV2" Namespace="FredCK.FCKeditorV2" TagPrefix="FCKeditorV2" %>
<FCKeditorV2:FCKeditor ToolbarSet="SmallBasic" ID="fck_content" runat="server" Width="100%" Height="290">
</FCKeditorV2:FCKeditor>
3、那个fckeditor文件夹放在网站根目录下，然后再Web.Config文件中<appSettings></appSettings>添加如下的几个配置项add。
<appSettings>
<add key="FCKeditor:BasePath" value="~/fckeditor/"/>
<!--FileUpLoad 配置-->
<add key="ServiceAddress" value=""></add>
<add key="UpLoadSize" value="102400"></add>
<add key="AbsouleUrl" value=""/>
<add key="RelativeUrl" value="upload_files\userFiles\"/>
<add key ="FCKeditor:UserFilesPath" value ="~/upload_files/userFiles/" />
<!--End FileUpLoad 配置-->
</appSettings>
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Admin_Default" %>
<%@ Register Assembly="FredCK.FCKeditorV2" Namespace="FredCK.FCKeditorV2" TagPrefix="FCKeditorV2" %>
