Hello,

I have a list of an enumeration: IList<Role> Roles and a variable Role
myRole.

Consider myRole value is Role.A. I need to:
- Add Role.A to IList<Role> only if IList<Role> does not contain
Role.A.
- If I add Role.A to Roles then I need to remove Role.C and Role.F
from list Roles if they exist.

How can I do this?

Thanks,
Miguel

Wouldn't that be using the IList.Contains(Role.A) ?
- If I add Role.A to Roles then I need to remove Role.C and Role.F
from list Roles if they exist.

It would be if contains, then find indexof and the removeat.
