سلام
من این کد رم برای restore بانکم مینویسم :

SqlCon.Open();
SqlCom.CommandText =
"RESTORE DATABASE Test FROM DISK='c:\\dbBackup.bak'";
SqlCom.Connection = SqlCon;
SqlCom.ExecuteNonQuery();
SqlCon.Close();

ولی خطا میده :

Exclusive access could not be obtained because the database is in use.
RESTORE DATABASE is terminating abnormally.
