一般的 Array 基类不是类型，所以不实现任何类型特定的接口;然而，可以直接投射向量 - GetValues 实际返回一个向量;所以：

The general Array base class is not typed, so it does not implement any type-specific interfaces; however, a vector can be cast directly - and GetValues actually returns a vector; so:

public static IEnumerable<SomeType> AllEnums
    = (SomeType[])Enum.GetValues(typeof(SomeType));

或更简单：

public static SomeType[] AllEnums 
    = (SomeType[])Enum.GetValues(typeof(SomeType));
