主要步骤如下：
1,在asp.net mvc项目中引入jqrte类库，声明辅助类用于存储服务器端上载文件的信息
复制代码 代码如下:
public class ViewDataUploadFilesResult
{
public string message { get; set; }
//public int Length { get; set; }
public string imagepath { get; set; }
public string error { get; set; }
}

2，编写处理文件上载服务器段代码，并将上载的文件信息返回给客户端，代码如下：
复制代码 代码如下:
[AcceptVerbs(HttpVerbs.Post)]
public JsonResult UploadFiles(FormCollection collection)
{
var r = new ViewDataUploadFilesResult();
foreach (string file in Request.Files)
{
string url = Request.Url.Authority;
url = "http://" + url;
HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
string date = DateTime.Now.Date.ToShortDateString();
string path = Path.Combine(
AppDomain.CurrentDomain.BaseDirectory,
"Content");
string datePath = Path.Combine(path,date);
Directory.CreateDirectory(datePath);
url += "/Content/";
url += date;
url += "/";
url += Path.GetFileName(hpf.FileName);
if (hpf.ContentLength == 0)
continue;
string savedFileName = Path.Combine(
datePath,
Path.GetFileName(hpf.FileName));
try
{
hpf.SaveAs(savedFileName);
}
catch (Exception e)
{
r.error = e.ToString();
}
//r.Name = savedFileName;
//r.Length = hpf.ContentLength;
r.imagepath = url;
r.message = "ok";
r.error = "ok";
//r.Add(new ViewDataUploadFilesResult()
//{
// Name = savedFileName,
// Length = hpf.ContentLength
//});
}
JsonResult jsonResult = Json(r);
jsonResult.ContentType = "text/html";
return jsonResult;
}

之所以搞了这么长时间，问题也主要出在这儿，开始用的是return json(r),发现jquery的回调函数总是无法获得服务器端的json，反而会跳出个下载文件对话框，反复阅读jquery的源代码，折磨了一周多后，在asp.net mvc官方论坛上注册了个用户，经过一番讨论，最后发现对于有file控件的ajax form，在action方法中应当制定json的contentType才会正确处理json对象，源代码如上，感谢热心朋友的帮助，要不然不知道这个问题会折磨到我什么时候（已经好几天睡不好觉了：()。原贴链接如下：http://forums.asp.net/t/1439867.aspx

3.修改jqrte的fileupload源代码，只要改一下action路径就行，在jquery.jqrte.min.js中修改uploads函数： 增加和修改的代码如下：
复制代码 代码如下:
var path = window.location.href.replace(/editor/, "UploadFiles");
// alert(path);
$.jQRTE.ajaxFileUpload({ url: path, secureuri: false, fileElementId: "upload" + uid + "_fileToUpload", dataType: "json",

4，准备编辑器页面，原代码如下：
复制代码 代码如下:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">

这样就可以在asp.net mvc中使用jqrte编辑器的强大功能了
