Fastest way to map result of SqlDataReader to object

I\'m comparing materialize time between Dapper and ADO.NET and Dapper. Ultimately, Dapper tend to faster than ADO.NET, though the first time a given fetch query was executed

I love that the most upvoted answer mentions @MarkGravel and his FastMember. But if you're already using Dapper, which is also a component of his, you can use Dapper's GetRowParser like this:

var parser = reader.GetRowParser(typeof(MyObject));

while (reader.Read())
{
    var myObject = parser(reader);
}
