(五)线程--定制线程及设置和获取线程的优先级别

(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!
