Return Value

Description

true

The HasValue property is false, and the other parameter is a null reference (Nothing in Visual Basic). That is, two null values are equal by definition.

-or-

The HasValue property is true, and the value returned by the Value property is equal to the other parameter.

false

The HasValue property for the current Nullable structure is true, and the other parameter is a null reference (Nothing in Visual Basic).

-or-

The HasValue property for the current Nullable structure is false, and the other parameter is not a null reference (Nothing in Visual Basic).

-or-

The HasValue property for the current Nullable structure is true, and the value returned by the Value property is not equal to the other parameter.

If the HasValue property of the current Nullable structure is true, equality is determined by passing the other parameter to the Equals method of the underlying value of the current Nullable structure.
