推荐答案

请参阅 AsyncFileUpload是一个ASP.NET AJAX控件，允许您异步上传文件到服务器。可以在服务器端和客户端检查文件上载结果。 See AsyncFileUpload is an ASP.NET AJAX Control that allows you asynchronously upload files to server. The file uploading results can be checked both in the server and client sides. <ajaxToolkit:AsyncFileUpload OnClientUploadError="uploadError" OnClientUploadComplete="uploadComplete" runat="server" ID="AsyncFileUpload1" Width="400px" UploaderStyle="Modern" UploadingBackColor="#CCFFFF" ThrobberID="myThrobber" />
