C#多线程间传入值和返回值问题

不喜欢说那么多废话，直接上代码，不懂看注释！站在代码面前，一切问题将不再是问题！

一、不带参数的线程

class main
{
public static void main(string[] args)
{
Thread th1 = new Thread(DoWork);
th1.Start();

Thread th2 = new Thread(new ParameterizedThreadStart(DoWorkWithParam));
object data = null;
th2.Start(data);
}

private void DoWork()
{
//do something
}

private void DoWorkWithParam(object param)
{
string data = param.ToString();
//do something
}

}

二、带一个参数

class main
{
public static void main(string[] args)
{
Thread th2 = new Thread(new ParameterizedThreadStart(DoWorkWithParam));
object data = null;
th2.Start(data);
}

private void DoWorkWithParam(object param)
{
string data = param.ToString();
//do something
}

}

三、带两个及两个以上的参数

public class ThreadWithParams {
private string param1;
private int param2;

public ThreadWithParams(string param1, int param2 )
{
this. param1 = param1 ;
this. param2 = param2;
}

public void ThreadProc()
{
Console.WriteLine(param1, param2);
}
}

public class Main{
public static void Main()
{
　　　　　　　　　　//初始化两个参数
ThreadWithParams twp = new ThreadWithState( "i am param1", 2);
Thread t = new Thread(new ThreadStart(twp.ThreadProc));
t.Start();
}
}
