C#

<br />
private Point _wallLocation;<br />
public Point WallLocation<br />
{<br />
    get{return _wallLocation;}<br />
    set{_wallLocation=value;}<br />
}<br />
<br />
And into your class constructor<br />
public Constructor()<br />
{<br />
    _wallLocation = new Point(0, 0);<br />
}<br />

the first option isn't good because I have an unassigned variable kicking around.

If I use the first example does that mean that the Point is actually allocated?

What is the best way to allocate a ValueType that has nothing stored in it if I can't null it?

struct MyStruct
{
   static MyStruct Empty
   {
      return new MyStruct(<Some Invalid Value>);
   }
}
