    n1 As Nullable(Of T), _
    n2 As Nullable(Of T) _
) As Integer

Dim n1 As Nullable(Of T)
Dim n2 As Nullable(Of T)
Dim returnValue As Integer

returnValue = Nullable.Compare(n1, n2)

[ComVisibleAttribute(true)] 
public static int Compare<T> (
    Nullable<T> n1,

) where T : struct

Parameters

n1: A Nullable object.

n2: A Nullable object.

Return Value

An integer that indicates the relative values of the n1 and n2 parameters.

Return Value	Description
Less than zero	The HasValue property for n1 is false, and the HasValue property for n2 is true. -or- The HasValue properties for n1 and n2 are true, and the value of the Value property for n1 is less than the value of the Value property for n2.
Zero	The HasValue properties for n1 and n2 are false. -or- The HasValue properties for n1 and n2 are true, and the value of the Value property for n1 is equal to the value of the Value property for n2.
Greater than zero	The HasValue property for n1 is true, and the HasValue property for n2 is false. -or- The HasValue properties for n1 and n2 are true, and the value of the Value property for n1 is greater than the value of the Value property for n2.
