使用 FastMember:

IEnumerable<SomeType> data = ...DataTable table = new DataTable();using(var reader = ObjectReader.Create(data)) {    table.Load(reader);}

This uses the FastMember‘s meta-programming API for maximum performance. If you want to restrict it to particular members (or enforce the order), then you can do that too:

IEnumerable<SomeType> data = ...DataTable table = new DataTable();using(var reader = ObjectReader.Create(data, "Id", "Name", "Description")) {    table.Load(reader);}
