Nullable(T).GetValueOrDefault Method

Retrieves the value of the current Nullable(T) object, or the object's default value.

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

member GetValueOrDefault : unit -> 'T 

Return Value

Type: T
The value of the Value property if the HasValue property is true; otherwise, the default value of the current Nullable(T) object. The type of the default value is the type argument of the current Nullable(T) object, and the value of the default value consists solely of binary zeroes.

The GetValueOrDefault method returns a value even if the HasValue property is false (unlike the Value property, which throws an exception).

The following code example retrieves the value of a Nullable(T) object if that value is defined; otherwise, it retrieves the default value or a specific default value.

No code example is currently available or this language may not be supported.
