Newline In C# + SQL?

Hi everyone!
I'm be stuck by a simple issue about newline in C# and has relative with SQL.
 I wrote a SQL sentence like that:
                        IF EXISTS(SELECT NAME FROM SYSOBJECTS WHERE NAME =  'TG1' AND TYPE = 'TR')" +
                          " DROP TRIGGER TG1" +
                          " GO " +
                          " CREATE TRIGGER TG1 ON FILES FOR DELETE AS DELETE table1 FROM" +
                          " table1 INNER JOIN DELETED ON DELETED.ID = table1.ID" +
                          " GO " +
                          " DELETE FROM table2 WHERE ID = 'ID00001'
It's executing ok in SQL but when execute programming then " GO " have to break newline (
or System.Environment.NewLine), However seem have not mean for SQL Execute becoz will be appear
in SQL sentence. 
I'm not  have experience about GO and TRIGGER so have any idea for this problem!
Thanks so much.
