.net - 构造函数调用其他构造函数: any performance issues?

Question

在性能至关重要的应用程序中，场景 1(完全独立的构造函数)与场景 2(链式调用构造函数)相比是否有任何明显的优势？

场景 1

Class TwoInts

    Private a, b As Integer

    Public Sub New(ByVal a As Integer, ByVal b As Integer)
        Me.a = a
        Me.b = b
    End Sub

    Public Sub New(ByVal a As Integer)
        Me.a = a
        Me.b = 0
    End Sub

    Public Sub New()
        Me.a = 0
        Me.b = 0
    End Sub

End Class

场景 2

Class TwoInts

    Private a, b As Integer

    Public Sub New(ByVal a As Integer, ByVal b As Integer)
        Me.a = a
        Me.b = b
    End Sub

    Public Sub New(ByVal a As Integer)
        Me.New(a, 0)
    End Sub

    Public Sub New()
        Me.New(0)
    End Sub

End Class

Answer 1

不，不会有明显的差异。

您可以运行自己的基准测试并找出答案。
