推荐答案

您需要将上传的图像保存到文件中，然后将ImageUrl设置为将图像保存到的路径.

You will need to save the uploaded image to a file and then set the ImageUrl to the path that you save the image to.

<br />
<pre lang="cs">if (fileuploadImage.HasFile)<br />
{<br />
     fileuploadImage.SaveAs(Server.MapPath("~/") + fileuploadImage.FileName);<br />
<br />
     Image1.ImageUrl = "~/" + fileuploadImage.FileName;<br />
}</pre><br />
