Stop program execution until threads complete

I have a console application that inits 4 theads to perform a long task. I want my program to wait until the threads are complete, and then complete the program execution. Is there a way to stop the program from executing, letting the threads complete their job?

From stackoverflow

• Threading.Thread.Join is what you are looking for.

  Edit: Examples here

• Depending upon how you're starting the 4 threads then WaitHandle.WaitAll might be a good place to start...

• Thread.Join is what you want.

• Load your application after those threads are joined e.g:

  Thread1.join();
  Thread2.join();
  Thread3.join();
  Thread4.join();
  
  
  startApplication();
  

  If you could provide me in more detail i can help you better.
