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

Int32

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`.
