如何在C#中重命名文件夹/目录？

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string sourcePath = @"C:\source\folder";
        string targetPath = @"C:\target\folder";

        try
        {
            Directory.Move(sourcePath, targetPath);
            Console.WriteLine("文件夹已成功重命名。");
        }
        catch (Exception ex)
        {
            Console.WriteLine("重命名文件夹时发生错误: " + ex.Message);
        }
    }
}

if (Directory.Exists(targetPath))
{
    Console.WriteLine("目标文件夹已存在。");
}
else
{
    Directory.Move(sourcePath, targetPath);
    Console.WriteLine("文件夹已成功重命名。");
}
