如何使用代码备份SQL Server数据库

1.添加引用

using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Common;

2.
Backup bkpDatabase = new Backup();
// Set the backup type to a database backup
bkpDatabase.Action = BackupActionType.Database;
// Set the database that we want to perform a backup on
bkpDatabase.Database = DbName;// cmbDatabase.SelectedItem.ToString();

// Set the backup device to a file
//new BackupDeviceItem(saveBackupDialog.FileName, DeviceType.File);
BackupDeviceItem bkpDevice = new BackupDeviceItem(NewName, DeviceType.File);

// Add the backup device to the backup
bkpDatabase.Devices.Add(bkpDevice);
// Perform the backup
bkpDatabase.SqlBackup(SD.SrvSql);
File.Copy(Source, PathDestination + "\\" + fileName);

File.Delete(Source);
