为同一方法定义多个线程的C#

using System;
using System.Threading;

class Program
{
    static void Main()
    {
        Thread thread1 = new Thread(Method);
        Thread thread2 = new Thread(Method);

        thread1.Start();
        thread2.Start();

        // 等待线程执行完成
        thread1.Join();
        thread2.Join();

        Console.WriteLine("所有线程执行完成");
    }

    static void Method()
    {
        // 线程执行的代码
        Console.WriteLine("线程ID: " + Thread.CurrentThread.ManagedThreadId);
    }
}

using System;
using System.Threading.Tasks;

class Program
{
    static void Main()
    {
        Task task1 = Task.Run(Method);
        Task task2 = Task.Run(Method);

        Task.WaitAll(task1, task2);

        Console.WriteLine("所有线程执行完成");
    }

    static void Method()
    {
        // 线程执行的代码
        Console.WriteLine("线程ID: " + Task.CurrentId);
    }
}
