 string filePath = HttpContext.Current.Server.MapPath(strFile);//路径
                FileInfo fileInfo = new FileInfo(filePath);
                string ContentType = fileName.Substring(fileName.LastIndexOf("."));
                //context.Response.Clear();
                //context.Response.ClearContent();
                //context.Response.ClearHeaders();
                //context.Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName);
                //context.Response.AddHeader("Content-Length", fileInfo.Length.ToString());
                //context.Response.AddHeader("Content-Transfer-Encoding", "binary");
                context.Response.ContentType = ContentType;
                context.Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
                context.Response.WriteFile(fileInfo.FullName);
