Nullable.Compare<T>(Nullable<T>, Nullable<T>) Method

Definition

Compares the relative values of two Nullable<T> objects.

public:
generic <typename T>
 where T : value class static int Compare(Nullable<T> n1, Nullable<T> n2);
public static int Compare<T> (T? n1, T? n2) where T : struct;
[System.Runtime.InteropServices.ComVisible(true)]
public static int Compare<T> (T? n1, T? n2) where T : struct;
static member Compare : Nullable<'T (requires 'T : struct)> * Nullable<'T (requires 'T : struct)> -> int (requires 'T : struct)
[<System.Runtime.InteropServices.ComVisible(true)>]
static member Compare : Nullable<'T (requires 'T : struct)> * Nullable<'T (requires 'T : struct)> -> int (requires 'T : struct)
Public Shared Function Compare(Of T As Structure) (n1 As Nullable(Of T), n2 As Nullable(Of T)) As Integer

Type Parameters

T

The underlying value type of the n1 and n2 parameters.

Parameters

n1
Nullable<T>

A Nullable<T> object.

n2
Nullable<T>

A Nullable<T> object.

Returns

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.
