C# object is not null but (myObject != null) still return false

Question

I need to do a comparaison between an object and NULL. When the object is not NULL I fill it with some data.

Here is the code :

 if (region != null)
         


        

Answer 1

So is it that these checks here are not right:

public static bool operator !=(Region r1, Region r2)
{
    if (object.ReferenceEquals(r1, null))
    {
        return false;
    }
    if (object.ReferenceEquals(r2, null))
    {
        return false;
    }
...
