推荐答案

您可以使用javascript上传完成后禁用文件上传按钮

You can disable file upload button after upload complete using javascript

<ajaxToolkit:AsyncFileUpload
            OnClientUploadError="uploadError" OnClientUploadComplete="uploadComplete"
            runat="server" ID="AsyncFileUpload1"    />
    <script type="text/javascript">

        function uploadError(sender, args) {

        }
        function uploadComplete(sender, args) {
document.getElementById("yourButtonID").disabled = true;

                    }
    </script>
