I'm trying to get the backup of a database but I am getting the error "database does not exist".

Код: Выделить всё

string master_ConnectionString = @"Data Source=(LocalDB)\MSSQLLocalDB;Database=Master;Integrated Security=True;Connect Timeout=30;"; string database = GetDataDirectory(); MessageBox.Show(database); using (SqlConnection masterdbConn = new SqlConnection()) {     masterdbConn.ConnectionString = master_ConnectionString;     masterdbConn.Open();     using (SqlCommand multiuser_rollback_dbcomm = new SqlCommand())     {          multiuser_rollback_dbcomm.Connection = masterdbConn;          multiuser_rollback_dbcomm.CommandText = @"ALTER DATABASE @DBNAME SET MULTI_USER WITH ROLLBACK IMMEDIATE";          multiuser_rollback_dbcomm.Parameters.AddWithValue("@DBNAME",database);          multiuser_rollback_dbcomm.ExecuteNonQuery();     }     masterdbConn.Close(); }         //SqlConnection.ClearAllPools();         //using (SqlConnection backupConn = new SqlConnection())         //{         //    backupConn.ConnectionString = "Data Source=(LocalDB)\\v11.0;AttachDbFilename=|DataDirectory|\\BbCon.mdf;Integrated Security=True;Connect Timeout=30;";         //    backupConn.Open();         //    using (SqlCommand backupcomm = new SqlCommand())         //    {         //        backupcomm.Connection = backupConn;         //        backupcomm.CommandText = @"BACKUP DATABASE BbCon TO DISK='c:\yourdbname.bak'";         //        backupcomm.Parameters.AddWithValue("@DBNAME", database);         //        backupcomm.ExecuteNonQuery();         //    }         //    backupConn.Close();         //} 

Database name is BbCon.mdf it is located at C:\Users\asus\Desktop\New Folder (3)\bbcon_accout_software\bbcon_accout_software\bin\x86\Debug
