How to close a thread

[Sidra Nisar]

Hi.
In my program, I'm initiating a thread in (console application) by getting a signal from my client(windowsf orm)who hits a connect button and it works the way i want.....
Now i am trying to close this thread when my client clicks on the disconnect button but i'm unable to find a way.

Kindly suggest what should be done to close the thread and terminate the form.

Here is the code I tried

//declaring a flag to keep a check on when the user hits disconnect

public int flag = 0;

//to start a thread  

private void button2_Click(object sender, EventArgs e)
        {
            readData = "Connected to Chat Server ...";
            msg();
            clientSocket.Connect("192.168.1.7", 5060);
            serverStream = clientSocket.GetStream();

            byte[] outStream = System.Text.Encoding.ASCII.GetBytes(textBox2.Text + "$" + textBox4.Text + "%");
            serverStream.Write(outStream, 0, outStream.Length);
            serverStream.Flush();

            Thread ctThread = new Thread(getMessage);
            ctThread.Start();
       if (flag == 10)
{
ctThread.Abort();
}
        }

// other processes

// When the client hits diconnect

  private void button3_Click_1(object sender, EventArgs e)
        {
            readData = "You have left the session";
            msg();

         // here i want to close the respective thread
    
flag = 10;
        }

The simplest way would be to declare ctThread as a private variable, assign it in button2_Click() and call it's Abort()-method in button3_Click_1 ()

e.g.

class xy {
  Thread ctThread = null;

  private void button2_Click(object sender, EventArgs e) {
   // ...
   ctThread = new Thread(getMessage);
   ctThread.Start();
   // ...
  }

private void button3_Click_1(object sender, EventArgs e) {
   // ...
   if(ctThread != null)
     ctThread.Abort();
   // ...
  }
}
