Can you add to an enum type in run-time

Question

If I have an enum type:

public enum Sport
{
    Tennis = 0;
    Football = 1;
    Squash = 2;
    Volleyball = 3;
}

Can I somehow add durin

Answer 1

I would create a complete Enum, with all the values you will ever need like this

Public enum Sport
{
    Tennis = 0;
    Football = 1;
    Squash = 2;
    Volleyball = 3;
    PingPong = 4;
    Rugby = 5;  // for example
}

And then keep a LIST of Invalid Sport entries, so the list would initially contain PingPong and Rugby. Every time you access the Enum, also check with your Invalid Sports list.

Then you can simply adjust your Invalid Sports List to suit, at any stage
