我想将其所有子文件夹和文件的文件夹从一个位置复制到另一个位置。这是最好的方法是什么？

I'd like to copy folder with all its subfolders and file from one location to another in .NET. What's the best way to do this?

我看到System.IO.File类的复制方法，但是想知道是否有一个更简单，更好或更快方法比抓取目录树。

I see the Copy method on the System.IO.File class, but was wondering whether there was an easier, better, or faster way than to crawl the directory tree.

推荐答案

好吧，有Steve引用的VisualBasic.dll实现，

Well, there's the VisualBasic.dll implementation that Steve references, and here's something that I've used.

private static void CopyDirectory(string sourcePath, string destPath)
{
    if (!Directory.Exists(destPath))
    {
        Directory.CreateDirectory(destPath);
    }

    foreach (string file in Directory.GetFiles(sourcePath))
    {
        string dest = Path.Combine(destPath, Path.GetFileName(file));
        File.Copy(file, dest);
    }

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