c# - 如何将目录和文件从一个外部复制到另一个 C# 控制台

Question

我曾因外部驱动器发生故障而运气不佳，并且在很多情况下几乎失去了一切。最后我有了创建一个控制台应用程序的想法，它可以自动“突袭”我的两个驱动器。现在就获取目录信息而言，我知道了。出于某种原因，当我尝试从一个复制到另一个时，它说访问被拒绝？有任何想法吗？这是我到目前为止所做的。 (我只是先做我的电影和电视来测试)

错误是“未经授权的访问异常:访问路径 'D:\External Backup\Movies and TV\Alien Quadrilogy' 被拒绝。”

        string _movieDIR = @"D:\External Backup\Movies and TV";
        string _movieDIR2 = @"G:\TEMP";
        string[] movies = Directory.GetDirectories(_movieDIR);


        foreach(string movie in movies)
        {
            File.Copy(movie, _movieDIR2);
        }
        Console.ReadLine();

更新完成的代码

        string _movieDIR = @"D:\External Backup\Movies and TV";
        string _movieDIR2 = @"G:\Movies and TV";
        string[] movies = Directory.GetDirectories(_movieDIR);

        if(Directory.Exists(@"G:\Movies and TV")){
            Console.WriteLine("Purging old Movies Folder in G:");
            Directory.Delete(@"G:\Movies and TV",true);
        }
        Console.WriteLine("Creating New Movies Folder in G:");
        Directory.CreateDirectory(@"G:\Movies and TV");

        double size = movies.Length;
        double percent = 0.00;
        double counter = 0;

        foreach(string movie in movies)
        {

           Console.Write("\n\nCopying " + movie.ToString());
           int pos = movie.IndexOf(@"V\");
           Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory(movie, _movieDIR2+ @"\" + movie.Substring(pos+2).ToString(),true);

           counter++;               
           percent = (counter / size)*100;
           percent = Math.Round(percent,2);
           Console.WriteLine("\n\nPercent Copied " + percent + "%\n\n");
        }
        Console.ReadLine();

如果您想复制目录，您可以使用 Microsoft.VisualBasic 命名空间中方便的 FileIO 方法。

    string _movieDIR = @"D:\External Backup\Movies and TV";
    string _movieDIR2 = @"G:\TEMP";
    string[] movies = Directory.GetDirectories(_movieDIR);

    foreach(string movie in movies)
    {
        Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory(_movieDIR, _movieDIR2);
    }
