Types are listed in C #

Question

I read this expression in a C # book.

Enumerations do not have to follow a sequential order and should not have unique values .

If I understand this statement, it means that one of them is acceptable (I don't know which one):

1.

enum EmpType
{
    Manager = 1,
    Grunt = 1,
    Contractor = 100,
    VicePresident = 9
}

2.

enum EmpType
{
    Manager = 10,
    Manager = 1,
    Contractor = 100,
    VicePresident = 9
}

Can someone explain to me? I thought C # should be a subset of C / C ++.

Answer 1

1 is correct, 2 is not.

As the book says, enumerations should not have unique values ​​(Example 2 shows enumerations with unique names). Names must be unique, as the compiler maps it to a value.

Answer 2
