Nullable<T>::Equals Method (Object^)

 

Indicates whether the current Nullable<T> object is equal to a specified object.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual bool Equals(
	Object^ other
) override

Parameters

other
Type: System::Object^

An object.

Return Value

Type: System::Boolean

true if the other parameter is equal to the current Nullable<T> object; otherwise, false.

This table describes how equality is defined for the compared values:

Return Value

Description

true

The HasValue property is false, and the other parameter is null. 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<T> structure is true, and the other parameter is null.

-or-

The HasValue property for the current Nullable<T> structure is false, and the other parameter is not null.

-or-

The HasValue property for the current Nullable<T> 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<T> structure is true and the other argument is not null, equality is determined by passing the other parameter to the Equals method of the underlying value of the current Nullable<T> structure.

The following code example determines whether an object and a Nullable<T> object are equal to the current Nullable<T> object.
