Question

有了这个：

  class outer
    public shared X as string = ""
    class inner
      public shared sub test()
        Dim s as string
        s = X ' refers to the shared (static) variable in outer
      end sub
    end class
  end class

测试方法中对X的引用是对外部类中声明的共享变量，但是，如果我的内部类通过该名称声明变量（从外部类中删除共享变量），我该如何获取访问权限对吗？

  class outer
    public shared X as string = ""
    class inner
      public X as string = "x"
      public shared sub test()
        Dim s as string
        s = X ' this fails because it's an attempt to access an instance variable
      end sub
    end class
  end class

Answer 1

尝试指定外部类的名称，如下所示：

Class outer
    Public Shared X As String = "bar"

    Class inner
        Public X As String = "foo"
        Public Shared Sub test()
            Dim s As String = X             ' foo
            Dim t As String = outer.X       ' bar
        End Sub
    End Class
End Class

访问隐藏的共享/静态变量
