代码示例：递归遍历文件夹实现目录拷贝

代码很简单。因为有人在坛子里问，所以从好久以前的旧工程里面搜出了这段代码。

public static bool CopyDirectory(string pathSrc, string pathDst){if(!Directory.Exists(pathSrc)){return false;}CreateFullPath(pathDst);DirectoryInfo directorySrc = new DirectoryInfo(pathSrc);DirectoryInfo directoryDst = new DirectoryInfo(pathDst);CopyDirectory(directorySrc, directoryDst);return true;}private static void CopyDirectory(DirectoryInfo srcDictionary, DirectoryInfo dstDictionary){FileInfo[] srcFiles = srcDictionary.GetFiles();foreach(FileInfo srcFile in srcFiles){File.Copy(srcFile.FullName, Path.Combine(dstDictionary.FullName, srcFile.Name), true);}DirectoryInfo[] directorySrcArray = srcDictionary.GetDirectories();foreach(DirectoryInfo directorySrc in directorySrcArray){string dstDirectoryFullPath = Path.Combine(dstDictionary.FullName, directorySrc.Name);DirectoryInfo directoryDst = new DirectoryInfo(dstDirectoryFullPath);CreateFullPath(directoryDst.FullName);CopyDirectory(directorySrc, directoryDst);}}
