GetValues
方法返回一个数组，其中包含枚举的每个成员
enumType
的值。 如果多个成员具有相同的值，则返回的数组包含重复值。 在这种情况下，使用返回的数组中每个值调用 方法不会还原分配给具有重复值
GetName
的成员的唯一名称。 若要成功检索枚举成员的所有名称，请调用
GetNames
方法。
GetValues
不能在仅反射上下文中使用反射来调用 方法。 相反，可以使用 方法检索所有枚举成员的值，获取表示枚举成员的 对象的数组，然后对数组的每个元素调用
Type.GetFields
FieldInfo
FieldInfo.GetRawConstantValue
方法。 下面的示例演示了此方法。 它要求在名为 Enumerations.dll 的程序集中定义以下枚举：
[Flags] enum Pets { None=0, Dog=1, Cat=2, Rodent=4, Bird=8,
Fish=16, Reptile=32, Other=64 };
<Flags> Public Enum Pets As Integer
None = 0
Dog = 1
Cat = 2
Rodent = 4
Bird = 8
Fish = 16
Reptile = 32
Other = 64
End Enum
程序集在仅反射上下文中加载，实例化表示枚举的对象，检索对象数组，字段值
