Answer 1

Add another space after Test , your SQL is built to ... TestTO DISK ... .

string line2 = "BACKUP DATABASE Test ";

As Onots pointed out, you should also escape some characters properly ( \\ introduces an escape sequence, \\ itself is escaped as \\\\ ):

string line2 = "TO  DISK = \'C:\\backup\\t1.bak\'";

See also MSDN: string (C# Reference) for details.

Answer 2

For SQL statements, it's easier to use a Verbatim string literal for the whole query rather than concatenating fragments. Eg

CreateTableCommand.CommandText = @"
BACKUP DATABASE Test
TO  DISK = 'C:\backup\t1.bak'
WITH 
NOFORMAT, 
COMPRESSION,
NOINIT,
NAME = N't1-Full Database Backup',
SKIP, 
STATS = 10;
";
