How to convert SQLce Datareader values to list?

If using loops,
then

using (var reader = cmd.ExecuteReader())
{
    var result = new List<Foo>();
    while (reader.Read())
    {
        var foo = new Foo 
        {
            Prop1 = reader.GetInt32(0),
            Prop2 = reader.GetString(1),
        }
        result.Add(foo);
    }
}

But if you dont want to use loops, then go for extension methods as mentioned in 
http://stackoverflow.com/questions/1464883/how-can-i-easily-convert-datareader-to-listt

You can use the following custom extension method also.

public static List MapDataToBusinessEntityCollection
(IDataReader dr)
   where T : new()
{
  Type businessEntityType = typeof (T);
  List entitys = new List();
  Hashtable hashtable = new Hashtable();
  PropertyInfo[] properties = businessEntityType.GetProperties();
  foreach (PropertyInfo info in properties)
  {
      hashtable[info.Name.ToUpper()] = info;
  }
  while (dr.Read())
  {
      T newObject = new T();
      for (int index = 0; index < dr.FieldCount; index++)
      {
          PropertyInfo info = (PropertyInfo)
                              hashtable[dr.GetName(index).ToUpper()];
          if ((info != null) && info.CanWrite)
          {
              info.SetValue(newObject, dr.GetValue(index), null);
          }
      }
      entitys.Add(newObject);
  }
  dr.Close();
  return entitys;
}
