工作中用到压缩文件，但为保证安全，选择先拷贝一份，压缩拷贝的，然后删除，然后C#中对于文件夹及其子文件夹的复制好像并不支持，所以自己写了一个，用的递归，不是很好。望高手指点。代码贴之：

class FileFolderHelp
    {
        public static void CopyFolder(string sourcePath, string distinationPath)
        {
            try
            {
                if (distinationPath[distinationPath.Length - 1] != Path.DirectorySeparatorChar)
                    distinationPath += Path.DirectorySeparatorChar;
                if (!Directory.Exists(distinationPath))
                    Directory.CreateDirectory(distinationPath);
                string[] fileList = Directory.GetFileSystemEntries(sourcePath);
                foreach (var one in fileList)
                {
                    if (Directory.Exists(one))
                        CopyFolder(one, distinationPath + Path.GetFileName(one));
                    else
                        File.Copy(one, distinationPath + Path.GetFileName(one), true);
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }
        }

        public static void DeleteFolder(string path)
        {
            try
            {
                string[] fileList = Directory.GetFileSystemEntries(path);
                foreach (var one in fileList)
                {
                    if (Directory.Exists(one))
                        DeleteFolder(path + Path.GetFileName(one));
                    else
                        File.Delete(path + Path.GetFileName(one));
                }
                Directory.Delete(path, true);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }
        }
    }
