How to put 0x0D 0x0A at the end of a txt file

Question

I have the end of the code of my txt file below and according to the recipe manual, asks me to put the characters 0x0D 0x0A at the end of the record.

How could I do that?

ATT01 = DETIM.ValidaATT(item.Cells["att"].Value.ToString()).PadRight(17, ' ');
ATT01 =   ATT01.Substring(0, ATT01Const);
Filler1 = Tamanho01.ToString().PadRight(2, ' ');
Filler1 = Filler1.Substring(0, Filler1const); //Acho que deveria ser colocado aqui mas não sei como!!
