劳器端接收图片的方

public System.Web.HttpPostedFile CurrentHttpPostedFile
        {
            get
            {
                HttpFileCollection files = Request.Files;
                if (files.Count == 0)
                {
                    return null;
                }
                else
                {
                    return files[0];
                }
            }
        }

图表处理就后每当页面输出数据作为JS的返回值

Response.ContentType = "text/plain";
                Response.Clear();
                Response.Write(returnText);
                Response.End();
