在Mustinherit类-VB.NET中返回self类型

我有一个抽象类

Public MustInherit Class GenericClass

    Public Sub New(Byval x as Integer)
        ' Some code here
    End Sub    

End Class

我将该类继承到另一个类，如下所示：

Public Class SpecificClass
    Inherits GenericClass

    Public Sub New(Byval x as Integer)
        MyBase.New(x)
    End Sub

End Class

我想添加一个

共享函数

，例如

magicFunction

，这样当我使用它时，它应该返回类型为

SpecificClass

的对象。我该怎么办

我想要这样的东西，但在VB.NET中是不允许的

Public MustInherit Class GenericClass

    Public Sub New(Byval x as Integer)
        ' Some code here
    End Sub    

    Public Shared Function magicFunction(Byval y as Integer) as GenericClass
        Dim z as Integer
        ' Some code here that will alter the value of z
        Return New GenericClass(z) ' Not allowed in VB.NET -- MustInherit class cannot have new
    End Sub    

End Class

调用继承的

SpecificClass

的

magicFunction

应返回

SpecificClass

的对象，如下所示：

Public Class ABC

    Public Function myAwesomeFunction as SpecificClass
        Dim objSpecificClass as SpecificClass
        objSpecificClass = SpecificClass.magicFunction(someInteger)
        Return objSpecificClass
    End Sub 

End Class

任何帮助都将不胜感激

这可能有助于：

Public MustInherit Class GenericClass(Of T As {GenericClass(Of T)})

    Public Sub New(ByVal x As Integer)
        ' Some code here
    End Sub

    Public Shared Function magicFunction(ByVal y As Integer) As GenericClass(Of T)
        Dim z As Integer
        ' Some code here that will alter the value of z
        Return Activator.CreateInstance(GetType(T), z)
    End Function

End Class

Public Class SpecificClass1
    Inherits GenericClass(Of SpecificClass1)

    Public Sub New(ByVal x As Integer)
        MyBase.New(x)
    End Sub

End Class

Public Class SpecificClass2
    Inherits GenericClass(Of SpecificClass2)

    Public Sub New(ByVal x As Integer)
        MyBase.New(x)
    End Sub

End Class  

用法：

    Dim a As SpecificClass1 = SpecificClass1.magicFunction(1)
    Dim b As SpecificClass2 = SpecificClass2.magicFunction(2)

可能的副本必须使用反射。类似于：

Activator.CreateInstance（Me.GetType）

@user1937198-我在这里发布问题之前阅读了这个问题并给出了答案。这不是我问题的重复。让我谷歌一下你的第二个建议-

Activator.CreateInstance（Me.GetType）

你的

泛型类“

不是泛型类。明白了。很好，正是我想要的。
