在asp.net中使用fckeditor比freetextbox复杂的多，但是这个是完全开源，开源自己控制
配置：web.config中

<appSettings>
<add key="FCKeditor:BasePath" value="~/fckeditor/"/>
</appSettings>

修改fckcofig.js文件(主要)

var _FileBrowserLanguage    = 'aspx' ;
var _QuickUploadLanguage = 'aspx'; 

修改config.asx文件，主要是为了实现不同用户的文件夹放置位置不同

private bool CheckAuthentication()
 {
 if (Session["vip"] == null ||Session["vip"].ToString() == "")
 {
 Session["vip"] = "public";
 }
 return true;
}
UserFilesPath = "../../../../../upload/" + Session["vip"].ToString();
string file_path = folder.Create_folder("../../../../../upload/" + Session["vip"].ToString());
 UserFilesAbsolutePath = file_path;TypeConfig[ "Image" ].AllowedExtensions            = new string[] { "bmp", "gif", "jpeg", "jpg", "png" };
 TypeConfig[ "Image" ].DeniedExtensions            = new string[] { };
 TypeConfig[ "Image" ].FilesPath                    = "%UserFilesPath%"+Session["vip"].ToString()+"/";
 TypeConfig[ "Image" ].FilesAbsolutePath            = ( UserFilesAbsolutePath == "" ? "" : "%UserFilesAbsolutePath%" );
 TypeConfig[ "Image" ].QuickUploadPath            = "%UserFilesPath%";
 TypeConfig[ "Image" ].QuickUploadAbsolutePath    = ( UserFilesAbsolutePath == "" ? "" : "%UserFilesAbsolutePath%" );
