示例1: Equals
' 导入命名空间
Imports System.Collections
Imports System.Collections.Generic
Public Class NanComparer : Implements IEqualityComparer
Public Overloads Function Equals(x As Object, y As Object) As Boolean _
Implements IEqualityComparer.Equals
If TypeOf x Is Single Then
Return CSng(x) = CSng(y)
ElseIf TypeOf x Is Double Then
Return CDbl(x) = CDbl(y)
Else
Return EqualityComparer(Of Object).Default.Equals(x, y)
End If
End Function
Public Overloads Function GetHashCode(obj As Object) As Integer _
Implements IEqualityComparer.GetHashCode
Return EqualityComparer(Of Object).Default.GetHashCode(obj)
End Function
End Class示例2: Example
Module Example
Public Sub Main()
Dim t1 = Tuple.Create(12.3, Double.NaN, 16.4)
Dim t2 = Tuple.Create(12.3, Double.NaN, 16.4)
' Call default Equals method.
Console.WriteLine(t1.Equals(t2))
Dim equ As IStructuralEquatable = t1
' Call IStructuralEquatable.Equals using default comparer.
Console.WriteLine(equ.Equals(t2, EqualityComparer(Of Object).Default))
' Call IStructuralEquatable.Equals using
' StructuralComparisons.StructuralEqualityComparer.
Console.WriteLine(equ.Equals(t2,
StructuralComparisons.StructuralEqualityComparer))
' Call IStructuralEquatable.Equals using custom comparer.
Console.WriteLine(equ.Equals(t2, New NanComparer))
End Sub
End Module输出：
True True True False
