Default Authentication and Role-Based Security

I'm using Daniel Cazzulino's excellent book "Beginning C# Web Applications with Visual Studio .NET". In his example in chapter 10 he creates a GenericPrincipal containg the role of a user (which will later show or hide a link to an admin page). Here is a code snippet :

sql = "SELECT IsAdministrator FROM [User] WHERE UserId='{0}'";
sql = String.Format(sql, id);
cmd = new SqlCommand(sql, con);

object admin = cmd.ExecuteScalar();

// Was it a valid UserID?
if (admin != null)
  GenericPrincipal ppal;
  string[] roles;

    // If IsAdministrator field is true, add both roles
    if (((bool)admin) == true)
        roles = new string[] {"User", "Admin"};
        roles = new string[] {"User"};


his role is stored as a boolean and inspected as such. But I have several roles which are probably better stored as int. Has anybody got any advice how I might achieve this? Something like :

int admin = cmd.ExecuteScalar();
if (admin == 1){roles = new string[] {"User", "Approver","Admin"};}
elsif (admin == 2){roles = new string[] {"User", "Approver"};}
else {roles = new string[] {"User"};}
