推荐答案

我猜这是一个权限问题.您需要为Upload(在您的情况下为"images")文件夹提供 write 权限.

它有任何错误吗?提供更多详细信息，以便可以识别出确切的问题.

您也可以检查此 msdn链接 [

I guess it''s a permission issue. You need to provide write permission to the Upload (''images'' in your case) folder.

Is it giving any error? Give more details so that exact issue can be identified.

You may also check this msdn link[^] about Uploading Files in ASP.NET. It also tells how to assign permissions to the upload folder.

只需使用

Just use

string imgname = UpImage.FileName;

代替

Instead of

string imgname = UpImage.PostedFile.FileName;

并尝试一下.

[为澄清我的答案而编辑]
UpImage.FileName仅返回文件名，例如xyz.gif
和UpImage.PostedFile.FileName返回完整路径，例如d:\ abc \ xyz.gif
因此隐藏(字符串路径=〜/images/" + imgname)将是未知位置，这就是为什么他面临错误.

and Give a Try.


UpImage.FileName returns just file name e.g. xyz.gif
and UpImage.PostedFile.FileName returns full path e.g. d:\abc\xyz.gif
so the concationation (string path = "~/images/"+ imgname) will be unknown location, thats why he is facing error.
