Overloading the comparison operator, how to compare if the two variables points to the same object(i.e. not value)
public static bool operator ==(Landscape a, Landscape b) { return a.Width == b.Width && a.Height == b.Height; } public static bool operator !=(Landscape a, Landscape b) { return !(a.Width == b.Width && a.Height == b.Height); }
Use the Object.ReferenceEquals static method.
Of course, in order for the == and != method to retain their full functionality, you should also be overriding Equals and GetHashCode so that they return a consistent set of responses to callers.
