递归遍历目录

代码很简单：

private void RecursiveDirectory(DirectoryInfo folder)
        {
            FileInfo[] files = folder.GetFiles();  
            foreach(FileInfo file in files)
            {
               //do something
            }

            DirectoryInfo[] subFolders = folder.GetDirectories( );
            if(subFolders == null || subFolders.Length == 0)
            {
                return;
            }
            foreach(DirectoryInfo subFolder in subFolders)
            {
                if(_isCancel)
                {
                    return;
                }
                RecursiveDirectory(subFolder);
            }
        }

调用：
DirectoryInfo root = new DirectoryInfo(path);
RecursiveDirectory(root);

递归的算法很简单，如果能掌握其精神，任何类似的代码都是手到擒拿。
