BuildErrorMessage ( object value, Type typeOperand, bool isSameType ) : string	Builds the error message related to the type comparison. This should be called only if the test failed (no matter it is negated or not). Warning: Should not call this method with nullable types. Indeed, the Nullable types are treated specially by CLR and it is impossible to have a boxed instance of a nullable type. Instead, boxing a nullable type will result in a null reference (if HasValue is false), or the boxed value (if there is a value).

value	object	The checked value.
typeOperand	System.Type	The other type operand.
isSameType	bool	A value indicating whether the two types are identical or not. true if they are equal; false otherwise.
