C#的多线程Thread函数调用

    这里讲如何用Thread类进行线程操作。在通过Thread实例化时，有一个线程委托的参数。在定义线程时有带参数和不带参数之分。
1. 不带参数：用ThreadStart
public void Main()
{
    Thread t = new Thread(new ThreadStart(NonParamThread));
    t.Start();
    Thread.Sleep(5000);
}

public void NonParamThread()
{
    Console.WriteLine("This is the sub thread.");
}

上述的NonParamThread没有参数，也没有返回值。
2. 带一个参数：用ParameterizedThreadStart，参数类型为object
public void Main()
{
    Thread t = new Thread(new ParameterizedThreadStart(OneParam));
    t.Start(12);
    Thread.Sleep(5000);
}

public void OneParam()
{
    Console.WriteLine("One Parameter Thread: " + obj.ToString());
}
3. 带多个参数： 一般定义一个类，将一个实例作为参数，仍用ParameterizedThreadStart
public class CParam
{
    private int a;
    private int b;
    public void SetValue(int i, int j)
    {
        a = i;
        b = j;
    }
    public int GetA()
    {
        return a;
    }
    public int GetB()
    {
        return b;
    }
}

public void Main()
{
    CParam p = new CParam();
    p.SetValue(11, 22);
    Thread t = new Thread(new ParameterizedThreadStart(MultiParam));
    t. Start(p);
    Thread.Sleep(5000);
}

public void MultiParam(object obj)
{
    CParam p = (CParam)obj;
    Console.WriteLine("MultiThread: " + p.GetA().ToString() + " and " + p.GetB().ToString());
}
