Question

I can send one parameter in the thread

class myThread
{
    Thread thread;
    public myThread(string name, int st)
    {
        thread = new Thread(this.Get_IP);
        thread.Name = name;
        thread.Start(st);//передача параметра в поток
        thread.Join();
    }
    void Get_IP(object st)
    {
        for (int ii = 0; ii < (int)st; ii++)
        {
            // smth
        }
    }
}

But i need to send two of them
for example

for (int ii = (int)st; ii < (int)fi; ii++)
{
    // smth
}

there is a way to put 2 params all together

void A(int a, int b) { }

and

ThreadStart starter = delegate { A(0, 10); };

But how can i send them to the thread?

Answer 1

Put the two variables as members in the class:

class MyThread {

  private Thread _thread;
  private int _start, _finish;

  public MyThread(string name, int start, int finish) {

    _start = start;
    _finish = finish;

    _thread = new Thread(Get_IP);
    _thread.Name = name;
    _thread.Start();
    _thread.Join();
  }

  void Get_IP() {
    for (int ii = _start; ii < _finish; ii++) {
      // smth
    }
  }

}

Note: Calling Join right after starting the thread makes is pretty pointless to use a thread.
