c# - 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 , Female =1, Unknown =2)

My question is how can I write something quick and nice to convert from their enum to mine?

Answer 1

Given Enum1 value = ..., then if you mean by name:

Enum2 value2 = (Enum2) Enum.Parse(typeof(Enum2), value.ToString());

If you mean by numeric value, you can usually just cast:

Enum2 value2 = (Enum2)value;

(with the cast, you might want to use Enum.IsDefined to check for valid values, though)
