You are getting an error, because GO is not a command that should be sent to the SQL Server engine. It is something recognized by tools like SSMS, sqlcmd and osql. It signals the end of the batch of T-SQL statements and serves as a signal that the commands so far (the current batch) should be send to the SQL Server engine.
You should not try to execute GO statements as T-SQL. You should either try to parse the file for GO lines, split it into separate batches and execute them one by one, or to make sure you are passing valid T-SQL contents in these files.
You can see more information about GO statement in SQL Server Utilities Statements - GO article.
