convert an enum to another type of enum

Question

I have an enum of for example \'Gender\' (Male =0 , Female =1) and I have another enum from a service which has its own Gender enum (Male =0

Answer 1

If we have:

enum Gender
{
    M = 0,
    F = 1,
    U = 2
}

and

enum Gender2
{
    Male = 0,
    Female = 1,
    Unknown = 2
}

We can safely do

var gender = Gender.M;
var gender2   = (Gender2)(int)gender;

Or even

var enumOfGender2Type = (Gender2)0;

If you want to cover the case where an enum on the right side of the '=' sign has more values than the enum on the left side - you will have to write your own method/dictionary to cover that as others suggested.
