大哥辛苦了，你给的好像和我要的有点区别。
还有你那个程序，每入口点运行不起赛！
thanks all the same!

Answer 5

最简单的办法 
TreeNode node = new TreeNode("我的电脑");
treeView.Nodes.Add(node);    //加入一个我的电脑节点string[] drivesName = System.IO.Directory.GetLogicalDrives()  //取得驱动器列表的集合
foreach(string name in drivesName)  //用foreach遍历集合
{
  TreeNode drivesNode = new TreeNode(name);
  node.Nodes.Add(drivesNode);     //加到我的电脑节点下
}
