WPF-TreeView遍历硬盘所有目录

首先在winform中做出了基本的界面

            if (Directory.Exists(path))

                FileSystemInfo[] files = dir.GetFileSystemInfos();

                    if (Directory.Exists(node.Tag.ToString()))
                    {
                        DirectoryInfo subDir = new DirectoryInfo(node.Tag.ToString());
                        if (subDir.Attributes != (FileAttributes.System | FileAttributes.Hidden | FileAttributes.Directory))
                        {
                            FileSystemInfo[] subFiles = subDir.GetFileSystemInfos();
                            if (subFiles.Length > 0)   //有子节点，先添加一个空节点
                            {
