基本使用示例：


using System;
using System.Threading;
 
namespace month_9_10._1009
{
    class Run5
    {
        /* 测试线程的调用过程
         * 主线程输出world，子线程输出hello
         */
        public static void showHello()
        {
            for(int i = 0; i < 100; i++)
            {
                Console.WriteLine($"Hello\t#{Thread.CurrentThread.Name}");
            }
        }
        public static void Main(string[] args)
        {
            Thread.CurrentThread.Name = "Main Thread!";
            var childThreadRef = new ThreadStart(showHello);
            Console.WriteLine("This is Main process!!!");
            var childThread = new Thread(childThreadRef);
            childThread.Name = "Child Thread!";
            childThread.Start();
            for (int i = 0; i < 100; i++)
            {
                Console.WriteLine($"World!\t#{Thread.CurrentThread.Name}");
            }
        }
    }
}
