推荐答案

建议您在此处详细说明您要执行的操作:是否要选择网络上的计算机，并且然后在所选计算机中选择一个文件夹?

您会收到什么错误消息?

请参阅此CP文章:"Rama Krishna Vavilala的.NET文件夹浏览器组件" [ ^ ].

如果那不起作用，请参阅:这是基于Vavilala的CP文章[

Suggest you tell us more here about exactly what you are trying to do: are you trying to select a computer on a network, and then select a folder within that selected computer ?

And what error message are you getting ?

See this CP article: "Folder Browser component for .NET By Rama Krishna Vavilala"[^].

If that doesn''t work then see: which is based on Vavilala''s CP article[^].

Are you using a version of .NET before 3.5; the reason I ask is I remember something on StackOverFlow about you would get an error trying to cast a number to an Environment.SpecialFolder if that were the case.

good luck, Bill
