LINQ using multiple role names while searching AD

Hello,

I need to ensure that I only get a user who is a part of one of the roles using linq but not sure how to provide a list of roles in the query. For example my requirement is to only get a user who is a part of either admin or custadmin role. Most of the examples I see have something like this for checking one role only:

var roleId = context.Roles.Where(m => m.Name == "admin").Select(m => m.Id).SingleOrDefault();

var users = context.Users
.Where(u => u.Roles.Any(r => r.RoleId == roleId)).ToList();

Thanks
John

    Hi @John Zeen ,
    I think you could use the language specific OR condition.Just like this:

    var roleId = context.Roles.Where(m => m.Name == "admin"|| m.Name=="custadmin").Select(m => m.Id).SingleOrDefault();
