構造函數調用vb.net其他構造一拉C＃

Question

在C＃中，你可以有

public class Foo 
{ 
    public Foo(string name) 
    { 
     //do something 
    } 

    public Foo(string name, int bar) : this(name) 
    { 
     //do something 
    } 
} 

是否有VB.Net相同呢？

Answer 1

它看起來在這方面類似於Java：

Public Class Foo 
    Public Sub New(name As String) 
     ' Do something ' 
    End Sub 

    Public Sub New(name As String, bar As Integer) 
     Me.New(name) 
     ' Do something ' 
    End Sub 
End Class 

注意，您必須在的情況下使用MyBase.New(...)要調用基類的構造函數。另見VB.NET OOP Part2 – Understanding Constructors。
