要使用OpenFileDialog，我需要使用命名空间System.Windows.Forms。

它不允许我在ASP.net中使用这个命名空间。我得到以下

错误消息：


错误CS0234：
$中不存在类型或命名空间名称''Windows'' b $ b namespace''System''（你错过了一个程序集引用吗？）

您是否希望能够选择然后上传文件？如果是这样，请使用

FileUpload控件。请参阅

To use OpenFileDialog, I need to use the namespace "System.Windows.Forms".
It doesn''t allow me to use this namespace in ASP.net. I get the following
error message:

error CS0234: The type or namespace name ''Windows'' does not exist in the
namespace ''System'' (are you missing an assembly reference?)

Are you wanting the ability to select and then upload a file? If so, use
the FileUpload control. See
http://msdn2.microsoft.com/en-us/library/ms227669.aspx for more info on how
to use the control.
