关于vb.net：如何列出枚举的成员

How to list Enum's members

如何在代码中列出枚举的成员？我有以下列举：

1
2
3
4
5
6

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

我试图通过以下代码列出testenum的所有成员，但失败了：

1
2
3
4
5
6
7
8
9
10
11
12

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：如何列出枚举的成员？

更新：解决方案是：

1
2
3
4
5
6
7
8
9
10

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

您需要向方法传递一个类型，而不是值。

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

如果有枚举的实例，也可以使用

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

如果你知道你想要的类型，我会推荐第一种方法。

您可以简单地迭代如下所示的所有值：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

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

For Each tstEnum As TestEnum In System.Enum.GetValues(GetType(TestEnum))

Response.Write(
String.Format("Name: {0} Value: {1}",
tstEnum.ToString,
CInt(tstEnum).ToString
)
)
