貌似很easy的样子web service：public void UploadInnerImg()
        {
            string fDir = @"/file/InnerImg/";
            string serverFDir = Server.MapPath(fDir);
            string fileName = "";
            string errorMsg = "";
            string script = @"
            <script type='text/javascript'>callFunction({0}, '{1}', '{2}');</script>        ";
            string funcNum = Request.QueryString["CKEditorFuncNum"];
            int cout = Request.Files.Count;
            if (cout > 0)
            {
                HttpPostedFileBase hpf = Request.Files[0];
                if (hpf != null)
                {
                    string fileExt = Path.GetExtension(hpf.FileName).ToLower();
                    //只能上传文件，过滤不可上传的文件类型    
                    string fileFilt = ".jpg .ico .gif .png .bmp";
                    if (fileFilt.IndexOf(fileExt) <= -1)
                    {
                        errorMsg = "file type is error.";
                    }
                    //判断文件大小    
                    int length = hpf.ContentLength;
                    if (length > 2097152)
                    {
                        errorMsg = "file length is error.";
                    }
                                        
                    DateTime nowTime = DateTime.Now;
                    fileName = nowTime.ToString("yyyyMMddHHmmssfff") + fileExt; 
                    if (!Directory.Exists(serverFDir))
                    {
                        Directory.CreateDirectory(serverFDir);
                    }
                    string filePath = serverFDir + fileName;
                    hpf.SaveAs(filePath);
                    Response.Write(string.Format(script, funcNum, fDir + fileName, errorMsg));
                }            }
