主要是参考MSDN的范例，简单的给出前台请求后台的处理：
public string uploadfile()        {            HttpContext.Response.ContentType = "application/json";            if (Request.Files.Count == 0)            {                return new                {                    success = false,                    err = "没有找到文件"                }.ToJson();            }            string fileName = Request.Files[0].FileName;            string ftpServerIP = asolution.config.Object.FileServers.FindByName("ftp").Host;  //框架web.config 配置的ftpip用户名和密码            string ftpUserID = asolution.config.Object.FileServers.FindByName("ftp").Uid;            string ftpPassword = asolution.config.Object.FileServers.FindByName("ftp").Pwd;            string fileType = fileName.Substring(fileName.LastIndexOf('.')).ToLower();            string fileFolder = "files";            if (fileType == ".jpg" || fileType == "bmp" || fileType == "jpeg" || fileType == "gif" || fileType == "png")            {                fileFolder = "images";            }            else if (fileType == ".avi" || fileType == ".swf")            {                fileFolder = "videos";            }                    string uri = ftpServerIP + "/editorUpload/" + fileFolder +"/"+fileName;            FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(uri));            reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);            reqFTP.KeepAlive = false;            reqFTP.Method = WebRequestMethods.Ftp.UploadFile;            reqFTP.UseBinary = true;            reqFTP.ContentLength = Request.Files[0].ContentLength;            int buffLength = 2048;            var fs = Request.Files[0].InputStream;            byte[] buff = new byte[buffLength];            int contentLen;            try            {                    Stream strm = reqFTP.GetRequestStream();                    contentLen = fs.Read(buff, 0, buffLength);                    while (contentLen != 0)                    {                        strm.Write(buff, 0, contentLen);                        contentLen = fs.Read(buff, 0, buffLength);                    }                    strm.Close();                    fs.Close();              }              catch(Exception e)               {                    return new                    {                        err = e,                        msg = ""                                            }.ToJson();               }                        return new {                 err = "",                 msg = new {                     url =ftpServerIP+"//editorUpload//" + fileFolder +"//"+fileName,                     localname = Request.Files[0].FileName }            }.ToJson();        }
