我正在尝试将图像作为base64字符串放入AjaxFileUpload中。我会在OnUploadCompleteAll中执行此操作吗?
protected void AjaxFileUpload1_UploadCompleteAll(object sender, AjaxFileUploadCompleteAllEventArgs e)
{
}
在aspx中:
<asp:AjaxFileUpload ID="AjaxFileUpload1" runat="server" AllowedFileTypes="jpg,jpeg,png,gif" MaximumNumberOfFiles="5" OnUploadCompleteAll="AjaxFileUpload1_UploadCompleteAll"></asp:AjaxFileUpload>
答案 0 :(得分:0)
当所有文件(在多重上传中)完成时,UploadCompleteAll
事件将触发。
还有一个事件会为每个上传的文件触发一次,称为UploadComplete
。你应该处理那件事。
// in ASPX page
<asp:AjaxFileUpload ID="AjaxFileUpload1"
runat="server"
AllowedFileTypes="jpg,jpeg,png,gif"
MaximumNumberOfFiles="5"
OnUploadCompleteAll="AjaxFileUpload1_UploadCompleteAll"
OnUploadComplete="AjaxFileUpload1_UploadComplete">
</asp:AjaxFileUpload>
在后面的代码中添加如下内容:
// in code-behind
protected void AjaxFileUpload1__OnUploadComplete(object sender, AjaxFileUploadEventArgs e)
{
if (e.ContentType.Contains("jpg") || file.ContentType.Contains("jpeg")
|| file.ContentType.Contains("png") || file.ContentType.Contains("gif"))
{
// file.FileName contains the name of the file
fileUploader.SaveAs(MapPath("path/where/you/want/to/save/file"));
// once saved, you can further manipulate the file if you wish
}
}
