DirectoryInfo
FileInfo
TreeViewDirectoryInfo.GetDirectories获得所有子目录。
DirectoryInfo.GetFiles获得所有的文件。把获得的子目录和文件绑定到TreeView的节点下，根据是文件还是目录创建不同的节点类型（DirNode:TreeNode,FileNode:TreeNode）。每个节点有Click事件，点击节点时触发这个Click事件，调用另一个方法。
DirectoryInfo.GetDirectories获得所有子目录。
DirectoryInfo.GetFiles获得所有的文件。 把获得的子目录和文件绑定到TreeView的节点下，根据是文件还是目录创建不同的节点类型（DirNode:TreeNode,FileNode:TreeNode）。 能将这几个具体实现吗？
