unity 复制Resources文件夹中一个名叫“a”的文件夹，并建立一个名叫“b”的新文件夹

您可以使用以下代码来复制名为“a”的文件夹并创建一个名为“b”的新文件夹：

using System.IO;
using UnityEngine;

public class CopyResourcesFolder : MonoBehaviour
{
    void Start()
    {
        string sourcePath = Application.dataPath + "/Resources/a";
        string destPath = Application.dataPath + "/Resources/b";

        if (!Directory.Exists(destPath))
        {
            Directory.CreateDirectory(destPath);
        }

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

        foreach (string folder in Directory.GetDirectories(sourcePath))
        {
            string folderName = new DirectoryInfo(folder).Name;
            string dest = Path.Combine(destPath, folderName);
            Directory.CreateDirectory(dest);
            CopyFolder(folder, dest);
        }
    }

    private void CopyFolder(string sourceFolder, string destFolder)
    {
        foreach (string file in Directory.GetFiles(sourceFolder))
        {
            string fileName = Path.GetFileName(file);
            string dest = Path.Combine(destFolder, fileName);
            File.Copy(file, dest, true);
        }

        foreach (string folder in Directory.GetDirectories(sourceFolder))
        {
            string folderName = new DirectoryInfo(folder).Name;
            string dest = Path.Combine(destFolder, folderName);
            Directory.CreateDirectory(dest);
            CopyFolder(folder, dest);
        }
    }
}

这段代码会在 Resources 文件夹下创建一个名为“b”的文件夹，并将名为“a”的文件夹及其所有内容复制到“b”文件夹中。请注意，如果“b”文件夹已经存在，则会被覆盖。
