推荐答案

您无法保留文件上载控件的值，每次呈现页面时该控件将为空.为什么要保留它的值?

You can''t retain the value of a file upload control, it will be empty every time the page is rendered. Why do you want to retain it''s value ?

您不能这样做.重新加载页面后，它将丢失文件名

you cant do that. once the page is reloaded it will lose the file name

在表单标签中使用enctype ="multipart/form-data".

< form id ="form1" runat ="server" enctype ="multipart/form-data">这样可以保持您的价值.

Use enctype="multipart/form-data" in form tag.

<form id="form1" runat="server" enctype="multipart/form-data"> This maintain your value.
