[RESOLVED] Serializing an Enum

[VitalyUr]

Hi all,

i need to backup a list filled with objects of this class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace XML2
{
    public enum userLevel { Manager, Librarian, Reader };
    [Serializable]
    public class Users
    {
        public string _username { get; set; }
        public string _password { get; set; }
        public userLevel _level { get; set; }
        public Users()
        {

        }
        public Users(string name, string password, userLevel level)
        {
            _username = name;
            _password = password;
            _level = level;
        }
    }
}

This is my list class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Serialization;
using System.IO;

namespace XML2
{

    [Serializable]
    public class userDB
    {
        List<Users> users = new List<Users>();
        public userDB()
        {
            
            users.Add(new Users("Administrator", "12345678", userLevel.Manager));
            users.Add(new Users("Librarian", "12345678", userLevel.Librarian));
            users.Add(new Users("Reader", "12345678", userLevel.Reader));
            save();
        }
        public void save()
        {
            XmlSerializer serializer = new XmlSerializer(typeof(List<Users>));
            using (FileStream fs = File.Open(@"users.xml", FileMode.Create))
            {
                serializer.Serialize(fs, users);
            }
        }
    }
}

When i execute it without the Enum it works fine but with it it crashes.
is there any solution for this?

Thanx in advance.

I'm using VS2008
