C # input values and return values between multiple threads

I don't like to talk so much nonsense. I can directly access the code without reading comments! Standing in front of the Code, all problems will no longer be a problem!

1. threads without Parameters

Class main
{
Public static void main (string [] args)
{
Thread th1 = new Thread (DoWork );
Th1.Start ();

Thread Th1 = 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
}

}

2. Include a parameter

Class main
{
Public static void main (string [] args)
{
Thread Th1 = new Thread (new ParameterizedThreadStart (DoWorkWithParam ));
Object data = null;
Th2.Start (data );
}

Private void DoWorkWithParam (object param)
{
String data = param. ToString ();
// Do something
}

}

3. Two or more parameters
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 ()
{// Initialize Two Parameters
ThreadWithParams twp = new ThreadWithState ("I am param1", 2 );
Thread t = new Thread (new ThreadStart (twp. ThreadProc ));
T. Start ();
}
}
