推荐答案

如果你的意思是控件类 System.Web.UI.WebControls.FileUpload ，这是ASP.NET类，它与 System.Windows.Forms 无关：

< a href =http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload%28v=vs.100%29.aspx> http://msdn.microsoft.com /en-us/library/system.web.ui.webcontrols.fileupload%28v=vs.100%29.aspx [ ^ ]，

< a href =http://msdn.microsoft.com/en-us/library/ms227677%28v=vs.100%29.aspx> http://msdn.microsoft.com/en-us/library/ms227677 ％28v = vs.100％29.aspx [ ^ ]。



如果你需要上传一些文件（s）到网站，这根本不是问题，但你的控件将是一个文件对话框或类似的东西。上传本身可以使用类 HttpWebRequest 或 FtpWebRequest 来完成，具体取决于文件的提供方式：

http://msdn.microsoft.com/en-us/library /system.net.webrequest.aspx [ ^ ]，

http ：//msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest.aspx [ ^ ] 。

If you mean the control class System.Web.UI.WebControls.FileUpload, this is the ASP.NET class, it has nothing to do with System.Windows.Forms:
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload%28v=vs.100%29.aspx[^],
http://msdn.microsoft.com/en-us/library/ms227677%28v=vs.100%29.aspx[^].

If you need to upload some file(s) to the Web site, this is not a problem at all, but your "controls" would be a file dialog or something like that. The upload itself could be done using the class HttpWebRequest or FtpWebRequest, depending on how the file is served:
http://msdn.microsoft.com/en-us/library/system.net.webrequest.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest.aspx[^].
