(五)线程--定制线程及设置和获取线程的优先级别(示例下载)

(一).描述
   此示例演示怎样定制一个线程，并且设置线程的主要属性和获取线程运行时的状态
(二).代码

   using System;
using System.Threading;
namespace 定制线程
{
 //委托声明(函数签名)
 //delegate string MyMethodDelegate();
 class MyClass
 {  
  public static void Method1()
  {
   int i;
   for(i=0;i<10;i++)
   {
    Console.WriteLine("Method1 at :" + i.ToString());
    
    //当线程停止/失败或未启动时IsAlive值为:false,否则为:true;
    Console.WriteLine("    IsAlive is " + Thread.CurrentThread.IsAlive.ToString()+" ");    
               
    //是否是后台进程
    Console.WriteLine("    IsBackGround is " + Thread.CurrentThread.IsBackground.ToString()+" ");    
    
    //线程名称
    Console.WriteLine("    Name is " + Thread.CurrentThread.Name.ToString()+" ");    
    
    //优先级
    Console.WriteLine("    Priority is " + Thread.CurrentThread.Priority.ToString()+" ");    
    
    //ThreadState值组合，有：启动/运行/等待/是否是后台线程等状态. 通过此属性来判断该线程是否完成任务.
    Console.WriteLine("    ThreadState is " + Thread.CurrentThread.ThreadState.ToString()+"\n\n ");    

    DelayTime(1);  //延长时间，模拟执行任务
   }
  }
  public static void Method2()
  {
   int i;
   for(i=0;i<10;i++)
   {
    Console.Write("Method2 at :" + i.ToString());

    //当线程停止/失败或未启动时IsAlive值为:false,否则为:true;
    Console.WriteLine("    IsAlive is " + Thread.CurrentThread.IsAlive.ToString()+" ");    
               
    //是否是后台进程
    Console.WriteLine("    IsBackGround is " + Thread.CurrentThread.IsBackground.ToString()+" ");    
    
    //线程名称
    Console.WriteLine("    Name is " + Thread.CurrentThread.Name.ToString()+" ");    
    
    //优先级
    Console.WriteLine("    Priority is " + Thread.CurrentThread.Priority.ToString()+" ");    
    
    //ThreadState值组合，有：启动/运行/等待/是否是后台线程等状态. 通过此属性来判断该线程是否完成任务.
    Console.WriteLine("    ThreadState is " + Thread.CurrentThread.ThreadState.ToString()+"\n\n ");           

    DelayTime(1);  //延长时间，模拟执行任务
   }
  }
  private static void DelayTime(int n)
  {
   DateTime startTime = DateTime.Now;
   while(startTime.AddSeconds(n) > DateTime.Now)
   {
    //延长时间,模拟实际中的进程
   }
  }

  [STAThread]
  static void Main(string[] args)
  {          
//   MyMethodDelegate d1 = new MyMethodDelegate(MyClass.Method1);
//   MyMethodDelegate d2 = new MyMethodDelegate(MyClass.Method2);
   
   Thread thread1 = new Thread(new ThreadStart(Method1));
   thread1.Name = "A";   //给线程定义名称
   //ThreadPriority枚举共五种优先级,由高->低依次为: Highest->AboveNormal->Normal->BelowNormal->Lowest
   //优先级高的先优先执行,相同优先级的线程具有相同对CPU争夺权力
   thread1.Priority = ThreadPriority.Highest;

            Thread thread2 = new Thread(new ThreadStart(Method2));   
   thread2.Name = "B";
   thread2.Priority = ThreadPriority.Normal;

            thread1.Start();
   thread2.Start();
   Console.Read();
  }
 }
}

本示例代码已经测试，能够正常运行!
