[求助]Thread运行顺序的问题。

using System;
using System.Threading;

public class ServerClass
{
// The method that will be called when the thread is started.
public void InstanceMethod()
{
Console.WriteLine(
"ServerClass.InstanceMethod is running on another thread.");

// Pause for a moment to provide a delay to make
// threads more apparent.
Thread.Sleep(3000);
Console.WriteLine(
"The instance method called by the worker thread has ended.");
}

public static void StaticMethod()
{
Console.WriteLine(
"ServerClass.StaticMethod is running on another thread.");

// Pause for a moment to provide a delay to make
// threads more apparent.
Thread.Sleep(5000);
Console.WriteLine(
"The static method called by the worker thread has ended.");
}
}

public class Simple
{
public static int Main(String[] args)
{
Console.WriteLine("Thread Simple Sample");

ServerClass serverObject = new ServerClass();

// Create the thread object, passing in the
// serverObject.InstanceMethod method using a
// ThreadStart delegate.
Thread InstanceCaller = new Thread(
new ThreadStart(serverObject.InstanceMethod));

// Start the thread.
InstanceCaller.Start();

Console.WriteLine("The Main() thread calls this after "
+ "starting the new InstanceCaller thread.");

// Create the thread object, passing in the
// serverObject.StaticMethod method using a
// ThreadStart delegate.
Thread StaticCaller = new Thread(
new ThreadStart(ServerClass.StaticMethod));

// Start the thread.
StaticCaller.Start();

Console.WriteLine("The Main() thread calls this after "
+ "starting the new StaticCaller thread.");

return 0;
}
}

Thread Simple Sample
The Main() thread calls this after starting the new InstanceCaller thread.
ServerClass.InstanceMethod is running on another thread.
The Main() thread calls this after starting the new StaticCaller thread.
ServerClass.StaticMethod is running on another thread.
线程 0x1eb8 已退出,返回值为 0 (0x0)。
线程 '<无名称>' (0x1b90) 已退出,返回值为 0 (0x0)。
The instance method called by the worker thread has ended.
线程 '<无名称>' (0x1da8) 已退出,返回值为 0 (0x0)。
The static method called by the worker thread has ended.
线程 '<无名称>' (0x1d80) 已退出,返回值为 0 (0x0)。
程序“[5308] msg.vshost.exe: 托管”已退出,返回值为 0 (0x0)。

这个是运行结果。

InstanceCaller.Start();

Console.WriteLine("The Main() thread calls this after "
+ "starting the new InstanceCaller thread.");

我的问题是:InstanceCaller.Start();以后,什么时候执行InstanceMethod()的方法?
是随机还是什么?

我以前理解的是要执行主进程Console.WriteLine("The Main() thread calls this after "
+ "starting the new InstanceCaller thread.");

Console.WriteLine("The Main() thread calls this after "
+ "starting the new StaticCaller thread.");

等这些全部执行完毕以后,才能够执行线程 。或者说在执行主进程的代码的时候,调用 thread.sleep()或者 InstanceCaller。join()才可以。

但是这个程序运行让我不明白。

那你的意思是InstanceCaller。start()开的线程跟主进程的优先级是一样的,按照语句运行的顺序,先运行InstanceCaller。start()里的委托方法?一定时间以后,无论完成与否,再执行主线程console。writeline()?

如果
public void InstanceMethod()
{
for (int j = 0; j < 10000000; j++) ; 新加的
Console.WriteLine("ServerClass.InstanceMethod is running on another thread.");
// Pause for a moment to provide a delay to make
// threads more apparent.
Thread.Sleep(3000);
Console.WriteLine(
"The instance method called by the worker thread has ended.");
}

执行结果:
Thread Simple Sample
ServerClass.InstanceMethod is running on another thread.这个为什么会提前执行呢?
The Main() thread calls this after starting the new InstanceCaller thread.
The Main() thread calls this after starting the new StaticCaller thread.
ServerClass.StaticMethod is running on another thread.

我的本意是如果系统质分配给InstanceCaller。start()一定时间的话,那么用一个空循环消耗其时间,使程序在还没有运行到InstanceCaller里面委托的方法的输出语句的时候就已经消耗掉系统分配给他运行的时间了,这样一来,就应该先执行consle.writeline()
结果恰恰相反,这是为什么?

我再研究研究,有问题的话明天再问。
谢了。。 。
