title: Simple C# Question: Nesting Classes, Accessibility
body: <p>I know this is probably simple, but I can't seem to figure out if it's possible to do this.</p>
  
  <p>I have the following code:</p>
  
  <pre><code>public class A {    
  thisMethod();  
  
   public class B {    
    someMethod();    
     }   
  }
  
  
  public class C {    
  A myA = new A();    
  A.B.someMethod();    
  }
  </code></pre>
  
  <p>Why can't I access B if I've already instantiated A?</p>
  
  <p>THanks for your help in advance!</p>
