Answer 1

配个好电脑 省担心这个问题 cpu自己解决

Answer 2

高优先级的线程可以完全阻止低优先级的线程执行，因此在改变线程的优先级时要特别小心。线程的优先级可以定义为ThreadPriority枚举的值，即Highest、AboveNormal、Normal、BelowNormal和 Lowest。

Answer 3

        //
        // Summary:
        //     The System.Threading.Thread can be scheduled after threads with AboveNormal
        //     priority and before those with BelowNormal priority. Threads have Normal
        //     priority by default.
        Normal = 2,

Answer 4

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace Ex_20_4
{
    class Program
    {
        static void Main(string[] args)
        {
            MyThreadClass o1 = new MyThreadClass("hackcat1,我的优先级是:Normal!");
            Thread t1 = new Thread(o1.ThreadMain);
            t1.Priority = ThreadPriority.Normal;
            t1.Start();
            MyThreadClass o2 = new MyThreadClass("hackcat2,我的优先级是:Normal!");
            Thread t2 = new Thread(o2.ThreadMain);
            t2.Priority = ThreadPriority.Normal;
            t2.Start();
            MyThreadClass o3 = new MyThreadClass("hackcat3,我的优先级是:Normal!");
            Thread t3 = new Thread(o3.ThreadMain);
            t3.Priority = ThreadPriority.Normal;
            t3.Start();
            MyThreadClass o4 = new MyThreadClass("hackcat4,我的优先级是:Normal!");
            Thread t4 = new Thread(o4.ThreadMain);
            t4.Priority = ThreadPriority.Normal;
            t4.Start();
            Console.Read();
        }
    }
    public class MyThreadClass
    {
        private String Msg;
        public MyThreadClass(String Msg)
        {
            this.Msg = Msg;
        }
        public void ThreadMain()
        {
            Console.WriteLine("字段Msg的值是{0}", Msg);
        }
    }
}
跑了10来次，发现每次结果都不一样，这个是不是随机的？
