c# - ASP.NET C# 使用 System.IO 复制目录和子目录

Question

我需要将整个目录C:\X复制到C:\Y\X，我还需要复制子文件夹。
有什么方法可以使用 System.IO.File\Directory 命名空间吗？
感谢所有帮助者!

此类将复制或移动文件夹，无需递归调用。
这些方法使用自己的堆栈来处理递归，这是为了避免 StackOverflowException。

public static class CopyFolder
{
    public static void CopyDirectory(string source, string target)
    {
        var stack = new Stack<Folders>();
        stack.Push(new Folders(source, target));

        while (stack.Count > 0)
        {
            var folders = stack.Pop();
            Directory.CreateDirectory(folders.Target);
            foreach (var file in Directory.GetFiles(folders.Source, "*.*"))
            {
                string targetFile = Path.Combine(folders.Target, Path.GetFileName(file));
                if (File.Exists(targetFile)) File.Delete(targetFile);
                File.Copy(file, targetFile);
            }

            foreach (var folder in Directory.GetDirectories(folders.Source))
            {
                stack.Push(new Folders(folder, Path.Combine(folders.Target, Path.GetFileName(folder))));
            }
        }
    }
    public static void MoveDirectory(string source, string target)
    {
        var stack = new Stack<Folders>();
        stack.Push(new Folders(source, target));

        while (stack.Count > 0)
        {
            var folders = stack.Pop();
            Directory.CreateDirectory(folders.Target);
            foreach (var file in Directory.GetFiles(folders.Source, "*.*"))
            {
                string targetFile = Path.Combine(folders.Target, Path.GetFileName(file));
                if (File.Exists(targetFile)) File.Delete(targetFile);
                File.Move(file, targetFile);
            }

            foreach (var folder in Directory.GetDirectories(folders.Source))
            {
                stack.Push(new Folders(folder, Path.Combine(folders.Target, Path.GetFileName(folder))));
            }
        }
        Directory.Delete(source, true);
    }
    public class Folders
    {
        public string Source { get; private set; }
        public string Target { get; private set; }

        public Folders(string source, string target)
        {
            Source = source;
            Target = target;
        }
    }
}
