C# - IDataReader to Object mapping using generics

Question

How can I map a DataReader object into a class object by using generics?

For example I need to do the following:

public class Mapper
    {
          


        

Answer 1

what about following

abstract class DataMapper
{
    abstract public object Map(IDataReader);
}

class BookMapper : DataMapper
{
   override public object Map(IDataReader reader)
   {
       ///some mapping stuff
       return book;
   }
}

public class Mapper
{
    public static List MapObject(IDataReader dr)
    {
        List objects = new List();
        DataMapper myMapper = getMapperFor(T);
        while (dr.Read())
        {
            objects.Add((T)myMapper(dr));
        }

        return objects;
    }

    private DataMapper getMapperFor(T myType)
    {
       //switch case or if or whatever
       ...
       if(T is Book) return bookMapper;

    }
}

Don't know if it is syntactically correct, but I hope u get the idea.
