asp.net的ajax文件上传控件出错

Question

当我尝试直接在asp.net上传文件时,我收到以下错误

index-1.jpg (image/jpeg) - 7.72 kb (error) (In red sign)

<ajaxToolkit:AjaxFileUpload ID="imageUploader" CssClass="uploadBox" OnUploadComplete="imageuploader_onUploadComplete" ThrobberID="imagethrobber" AllowedFileTypes="jpg,jpeg,png,bmp" MaximumNumberOfFiles="1" runat="server" />

以下是我的代码.

            //=========== Uploaded file format ============================
            string filename = e.FileName;

            //============== Upload the file ==============================
            imageUploader.SaveAs("~/articleimage/"+filename);

请帮助我解决这个问题.我正在使用visual studio 2010,.net 4和ajaxcontroltoolkit for 2010.
