如何在c＃TreeView中解决主目录和“我的电脑”

Question

I am making a file system TreeView. I want the initial four items to be

+Computer

+Desktop

+My Documents

+C:\\

These will all be pre-populated so that when the + is clicked, the subdirectories appear and are immediately themselves populated. Works great for C:\\ -- just like windows explorer. But the other three just show as names. They clearly don't relate to the actual filesystem locations. How do I add the other three filesystem locations? I tried:

 TreeNode my_computer = new TreeNode("Computer");
 TreeNode desktop = new TreeNode(@"%UserProfile%\Desktop");
 TreeNode c_drive = new TreeNode(@"C:\");
 TreeNode my_documents = new TreeNode(@"%UserProfile%\My Documents");

and also without %UserProfile%. Neither work.

You may want to look into Environment.SpecialFolder enumeration:
