ASP.NET C＃复制目录与SubDirectories与System.IO [英] ASP.NET C# Copy Directory with SubDirectories with System.IO

问题描述

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。

有任何方法使用System.IO.File \Directory命名空间吗？

感谢所有帮助者！

I need to copy a whole directory C:\X to C:\Y\X, and I need the sub-folders to be copied as well.
Is there any way to do it with the System.IO.File\Directory namespaces ?
Thanks for all helpers!

此类将复制或移动文件夹，而不进行递归调用。

方法使用自己的堆栈处理递归，这是为了避免 StackOverflowException 。

This class will copy or move a folder, without recursive calls.
The methods is using their own stacks to handle recursion, this is to avoid 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;
        }
    }
}
