vb.net – 如何列出枚举的成员

如何在代码中列出枚举的成员？我有以下枚举：

Public Enum TestEnum As int32
    First = 0
    Second = 2
    Third = 4
    Fourth = 6
End Enum

我尝试通过以下代码列出TestEnum的所有成员,但失败：

Public Class Form1

    Private Sub Button1_Click(sender As System.Object,e As System.EventArgs) Handles Button1.Click
        Dim Enum1 As TestEnum

        Dim Members() As String

        Members = System.Enum.GetNames(CType(Enum1,System.Enum))


    End Sub
End Class

所以我的问题是：如何列出枚举成员？

更新：解决方案是：

Public Class Form1

    Private Sub Button1_Click(sender As System.Object,e As System.EventArgs) Handles Button1.Click
        Dim Members() As String
        Members = System.Enum.GetNames(GetType(TestEnum))

        MessageBox.Show(Join(Members,Chr(13) & Chr(10)))

    End Sub
End Class

你需要传递一个类型,而不是一个值,方法.

Members = System.Enum.GetNames(GetType(TestEnum))

如果你有一个枚举的实例,你也可以使用

Members = System.Enum.GetNames(Enum1.GetType())

虽然如果你知道你想要的类型,我会推荐第一种方法.
