Question

I have created a model UserModel that holds MembershipUser and string[] Roles for each user. In my controller I’m trying to return an IEnumerable<UserModel> to the view but running into issues.

Cannot convert source type ‘IEnumerable<{user:MembershipUser, roles:string[]}>‘ to target type ‘IEnumerable<UserModel>‘

My Model

public class UserModel {
    public MembershipUser user { get; set; }
    public string[] roles { get; set; }
}

And in my controller

public ActionResult Users() {
    IEnumerable<UserModel> model = from MembershipUser u in Membership.GetAllUsers()
                select new {user = u, roles = Roles.GetRolesForUser(u.UserName)};

    return View(model);
}

Answer 1

You are selecting an anonymous type when I think you want your UserModel.

public ActionResult Users() {
    IEnumerable<UserModel> model = from MembershipUser u in Membership.GetAllUsers()
                select new UserModel {user = u, roles = Roles.GetRolesForUser(u.UserName)};

    return View(model);
}
