【C#】创建线程的四种方式

using System;
using System.Threading;

class Program
{
    static void Main(string[] args)
    {
        Thread thread1 = new Thread(new ThreadStart(method));
        thread1.Start();
        Thread thread2 = new Thread(delegate() {  Console.WriteLine(Thread.CurrentThread.ManagedThreadId + "通过匿名委托创建线程"); });
        thread2.Start();
        Thread thread3 = new Thread(()=> Console.WriteLine(Thread.CurrentThread.ManagedThreadId + "通过lambda表达式创建线程"));
        thread3.Start();
        Thread thread4 = new Thread(new ParameterizedThreadStart(method2));
        thread4.Start("通过有参委托创建线程");
    }

    static void method()
    {
        Console.WriteLine(Thread.CurrentThread.ManagedThreadId+ "通过无参【静态】方法创建线程");
    }
    static void method2(object obj)//参数必须是obj,后面再向下转
    {
        string s = Thread.CurrentThread.ManagedThreadId + (string)obj;
        Console.WriteLine(s);
    }
