title: Clarification on updating GUI from a separate Thread using an anonymous method
body: <p>I've found what looks like a very simple solution to my current situation.</p>
  
  <p>My current situation is that I want to do some I/O-heavy operations on a new Thread, so that I do not bog down my GUI Thread. I have a function written, as a member of my Form, that does these I/O operations already, but running it on the GUI Thread really makes the application a pain to use. So my plan was to just run this function in a new Thread. So, I created a Thread variable, in my form, and am trying to get it to use that function as the ThreadStart parameter. It does not seem to like it, though.</p>
  
  <p>I found an elegant looking solution, as a response to another thread, <a href="https://stackoverflow.com/a/661662/1549298">here</a>.</p>
  
  <pre><code>///...blah blah updating files
  string newText = "abc"; // running on worker thread
  this.Invoke((MethodInvoker)delegate {
      someLabel.Text = newText; // runs on UI thread
  });
  ///...blah blah more updating files
  </code></pre>
  
  <p>From the looks of that response, I could run this function in a new Thread and then use an anonymous function to update my Form when the Thread has finished its calculations. I'm just not good enough to fill in the blanks from that response, though.</p>
  
  <p>Everything I seem to read about Threads says that my ThreadStart function needs to be a static method in a new class. That response seems to suggest that I can do it within my Form class though, so that the <code>this</code> reference still references my Form instance. Otherwise, if my ThreadStart parameter were a different class, I'd have to pass in references to the Form instance, and that seems like more code, right?</p>
  
  <p>Would anybody mind helping me fill in the context for that response? Thanks in advance!</p>
