Restoring the Differential backup file after the full back up restore

Hi All,

This is my full back up restore script

RESTORE DATABASE VSO 
FROM DISK = 'C:\DBbackup\\\VSO.bak' WITH 
MOVE N'VSO' TO N'C:\PrestageRestoreTest\DATA_LOG\\VSO_Primary.mdf',
MOVE N'VSO_log' TO N'C:\PrestageRestoreTest\DATA_LOG\\VSO_Primary.ldf', 
 NOUNLOAD,  REPLACE,  STATS = 10;

After that i want restore Differential back up file on top of that , what   is the script?
