How to make class generic to pass dynamic property class in c#

Question

I have demo code which ignores the Extra property. I need to make this class generic.

public class HelloFriend 
{
    public static void Main(string[] args)
    {
        var s = new StringBuilder();
        s.Append("Id,Name\r\n");
        s.Append("1,one\r\n");
        s.Append("2,two\r\n");
        using (var reader = new StringReader(s.ToString()))
        using (var csv = new CsvReader(reader))
        {
            csv.Configuration.RegisterClassMap<TestMap>();
            csv.GetRecords<Test>().ToList();
        }
    }
}

public class Test : Test1
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public abstract class Test1
{
    public decimal Extra { get; set; }
}

public class TestMap : CsvClassMap<Test>
{
    public TestMap()
    {
        AutoMap();
        Map(m => m.Extra).Ignore();
    }
}

As shown in above code if I need to use different Test1, or Test2 instead of Test, then I need to write another TestMap class. How can I avoid this? How can I make this class generic, so I can pass multiple classes like Test to ignore the Extra property?

Do you mean somehting like this?

class Program
{
    public static void Main(string[] args)
    {
        var s = new StringBuilder();
        s.Append("Id,Name\r\n");
        s.Append("1,one\r\n");
        s.Append("2,two\r\n");
        using (var reader = new StringReader(s.ToString()))
        using (var csv = new CsvReader(reader))
        {
            csv.Configuration.RegisterClassMap<TestMap<Test>>();
            csv.GetRecords<Test>().ToList();
        }
    }
}
public class Test : Test1
{
    public int Id { get; set; }
    public string Name { get; set; }

}

public Abstract class Test1 
{
   public decimal Extra { get; set; }
}


public class Test2 : Test1
{
    //other propertys
}


public class TestMap<T> : CsvClassMap<T> where T : Test1
{
    public TestMap()
    {
        AutoMap();

            Map(m => m.Extra).Ignore();

    }
}
