                if (document.getElementsByName("file_upload1")[0].files[0] != null) {
                    //console.log(FileInfoNo)
                    $("#form_file").form("submit", {
                        url: '../ashx/upload/upload.ashx?action=editfile',
                        onSubmit: function (param) {
                            return $(this).form('validate');
                        },
                        success: function (jsonResult) {
                            $.show_warning_inframe(jsonResult, 'success');
                            $('#editfile').dialog('close');
        
                        }
                    });


                } else {
                    $.show_warning_inframe("请添加要修改的文件！", 'success');
                }
            }

C#后台

HttpPostedFile file = context.Request.Files[0];
file.FileName
file.ContentLength
FileSize = Decimal.Round(Convert.ToDecimal(file.ContentLength) / 1024, 2)

通过HttpPostedFile 获取到file，基本上就是这几种
如果想将整个文件存入数据库，必须要把 filename、ContentLength、FileSize一并存入，以SqlServer为例，要将ContentLength存入表字段类型为image
