title: How can I reference a method from another class without instantiating it?
body: <p>I don't want to create an object because it won't affect my visible form. How can I call a method so it does its thing in the visible side of things.</p>
  
  <pre><code>public class foo
  {
     public void SetString(string foo)
     {
         label1.Text = foo;
     }
  }
  </code></pre>
  
  <p>Inside another class:</p>
  
  <pre><code>foo X = new foo();
  X.SetString("testlololol");
  </code></pre>
  
  <p>This will set the label, but VIRTUALLY, I won't be able to see it on my form.</p>
  
  <p>How can I do the same thing, but on my VISIBLE side of things?</p>
