title: How can I wait for a thread to finish with .NET?
body: <p>I've never really used threading before in C# where I need to have two threads, as well as the main UI thread. Basically, I have the following.</p>
  <pre><code>public void StartTheActions()
  {
    // Starting thread 1....
    Thread t1 = new Thread(new ThreadStart(action1));
    t1.Start();
  
    // Now, I want for the main thread (which is calling `StartTheActions` method)
    // to wait for `t1` to finish. I've created an event in `action1` for this.
    // The I wish `t2` to start...
  
    Thread t2 = new Thread(new ThreadStart(action2));
    t2.Start();
  }
  </code></pre>
  <p>So, essentially, how can I have a thread wait for another one to finish? What is the best way to do this?</p>
