vb.net – 构造函数中的构造函数

这是一个坏主意吗？在公共构造函数中调用泛型私有构造函数是否会创建多个实例,或者这是初始化类变量的有效方法？

Private Class MyClass
    Dim _msg As String

    Sub New(ByVal name As String)
        Me.New()
        'Do stuff
    End Sub

    Sub New(ByVal name As String, ByVal age As Integer)
        Me.New()
        'Do stuff
    End Sub

    Private Sub New() 'Initializer constructor
        Me._msg = "Hello StackOverflow"
        'Initialize other variables
    End Sub
End Class

这是一种有效的方法.有一些警告可以调用新函数：

The Sub New constructor can run only once when a class is created. It
cannot be called explicitly anywhere other than in the first line of
code of another constructor from either the same class or from a
derived class.
