c# - Get a enum value

I am stuck with a piece code
There is a object, a field of which returns an enum (getter) the field is set by a function after reading from database. For example

Enum fiscalperiond
{
    Num1 = 12;
    Num2 = 13;
}

Class A

{

    Public Fiscalperiod
    {
        NumberOfFiscalPeriod {get;set;}
    }
}

Now I want to do this how do I do it

A a = new A();

int k = a.NumberOfFiscalPeriod;
