Directoy，DirectoryInfo文件夹的操作

实现一个文件复制到另一个文件夹的操作，并删除当前文件的内容，保留父目录

 class Program
    {
        static void Main(string[] args)
        {
            string Path1 ="D:\\cs\\28";
            string Path2 ="D:\\cs\\29";
            Move(Path1,Path2);
            Console.ReadKey();
        }
        public static void Move(string sourcepath,string desirpath)
        {
            string s =sourcepath;
            //如果源目录不存在，则创建该目录
            if (!Directory.Exists(sourcepath))
            {
                Console.WriteLine("父目录不存在");
            }
            if(!Directory.Exists(desirpath)){
                Console.WriteLine("源目录不存在");
            }
            if (Directory.Exists(sourcepath))
            {


                DirectoryInfo info = new DirectoryInfo(sourcepath);
                FileInfo[] oldFiles = info.GetFiles();
                DirectoryInfo[] oldDire = info.GetDirectories();//获取当前目录的文件夹
                try
                {
                    if (oldFiles.Length > 0)
                    {

                        for (int i = 0; i < oldFiles.Length; i++)
                        {
                            string source = sourcepath + "\\" + oldFiles[i].Name;
                            string desir = desirpath + "\\" + oldFiles[i].Name;
                            File.Copy(source, desir,true);
                        }
                    }
                    if (oldDire.Length > 0)
                    {
                        for (int i = 0; i < oldDire.Length; i++)
                        {
                            //Console.WriteLine();
                            Directory.CreateDirectory(desirpath+"/"+oldDire[i].Name);
                            Move(sourcepath + "\\" + oldDire[i].Name, desirpath + "\\" +oldDire[i].Name);
                        }
                    }
                }
                catch (Exception e){
                    Console.WriteLine("存在同名文件");
                }
            }
            DirectoryInfo dir = new DirectoryInfo(s);
            dir.Delete(true);
            Directory.CreateDirectory(s);
        }
    }
