如何使用.NET创建具有特定扩展名的临时文件？

dotnet new console -o MyTempFileApp
cd MyTempFileApp

using System;
using System.IO;

namespace MyTempFileApp
{
    class Program
    {
        static void Main(string[] args)
        {
            string extension = ".txt";
            string tempFilePath = Path.Combine(Path.GetTempPath(), $"temp{Guid.NewGuid()}{extension}");

            using (FileStream fs = File.Create(tempFilePath))
            {
                Console.WriteLine($"临时文件已创建：{tempFilePath}");
            }

            Console.ReadLine();
        }
    }
}

dotnet run
