This assumes you already have a Shape class with a Color property:

class test
{
     private Shape myShape;

     function a()
     {
          myShape = new Shape();
          myShape.Color = SomeColor;
     }

     function b()
     {
          Color color = myShape.Color;
     }
}

If you declare myShape in function scope, you can't expect to get to it outside that function's scope. Instance variables are not global in scope, but are avaiable to all instance methods of a class.

Ozymandias' example instantiates myShape in the constructor so you don't have to do it in a() or b() but both can still access it.
