        File.Copy(file, dest);
    }

    foreach (string folder in Directory.GetDirectories(sourcePath))
    {
        string dest = Path.Combine(destPath, Path.GetFileName(folder));
        CopyDirectory(folder, dest);
    }
}

推荐答案

我认为在您的第二个循环中，您想替换

I think in your second loop you want to replace

string dest = Path.Combine(destPath, Path.GetFileName(folder));

与

with

string dest = Path.Combine(destPath, Path.GetDirectoryName(folder));

看起来您的代码类似于此处的代码:

http://msdn.microsoft.com/en-us/library/bb762914.aspx [ ^ ]

我建议您阅读该MSDN文章，并弄清楚为什么每个部分都在做自己正在做的事情.最后，您只需要复制并粘贴代码即可使用，但是如果您真正了解它在做什么的原因，那么对您来说会更好.

It looks like your code is similar to what is here:

http://msdn.microsoft.com/en-us/library/bb762914.aspx[^]

I would recommend you go through that MSDN article and figure out why each piece is doing what it is doing. In the end, you could just copy and paste the code and it would work but it is much better for you if you actually learn why it is doing what it is doing.

您可能正在路径有问题.如果最后有一个斜杠，那么您有问题.以下似乎有效:

You probably are having problems with the path. If you have a slash at the end, then you have a problem. The following seems to work:

private static void CopyDirectory(string sourcePath, string destPath)
{

  if (!Directory.Exists(destPath))
  {
    Directory.CreateDirectory(destPath);
  }
  var fixedSource = new DirectoryInfo(sourcePath);
  var fixedDest = new DirectoryInfo(destPath);

  foreach (var file in fixedSource.GetFiles())
  {
    string dest = Path.Combine(fixedDest.FullName, file.Name);
    file.CopyTo(dest);
  }

  foreach (var folder in fixedSource.GetDirectories())
  {
    string dest = Path.Combine(destPath, folder.Name);
    CopyDirectory(folder.FullName, dest);
  }
}

这不是我建议您这样做的方式.我将有一个非递归方法来解决所有路径问题，然后您的代码可以工作，但是您可能会遇到重复问题，并且还需要处理.

This is not the way I would recommend that you do it. I would have a non-recursive method that would fix any path issues, then your code will work, but you may have an issue with duplicates, and you need to deal with that also.
