The object for which to get a hash code.
A hash code for the specified object.
The type of obj is a reference type and obj is null.
Implementations are required to ensure that if the Equals(T, T) method returns true for two objects x and y, then the value returned by the GetHashCode(T) method for x must equal the value returned for y.
