c#程序备份数据库的方法

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

public void BackupDatabase(SqlConnectionStringBuilder csb, string backupPath)
        {
            // 创建服务器连接对象
            ServerConnection connection = new ServerConnection(csb.DataSource, csb.UserID, csb.Password);

            try
            {
                // 连接到服务器
                Server server = new Server(connection);

                // 创建备份对象
                Backup backup = new Backup();
                backup.Action = BackupActionType.Database;
                backup.Database = csb.InitialCatalog;

                // 设置备份路径
                BackupDeviceItem backupDevice = new BackupDeviceItem(backupPath, DeviceType.File);
                backup.Devices.Add(backupDevice);

                // 执行备份操作
                backup.SqlBackup(server);
            }
            catch (Exception ex)
            {
                // 处理异常
                Console.WriteLine("备份数据库出错：" + ex.Message);
            }
            finally
            {
                // 关闭连接
                connection.Disconnect();
            }
        }

        public void RestoreDatabase(SqlConnectionStringBuilder csb, String backUpFile)
        {
            ServerConnection connection = new ServerConnection(csb.DataSource, csb.UserID, csb.Password);
            Server sqlServer = new Server(connection);
            Restore rstDatabase = new Restore();
            rstDatabase.Action = RestoreActionType.Database;
            rstDatabase.Database = csb.InitialCatalog;
            BackupDeviceItem bkpDevice = new BackupDeviceItem(backUpFile, DeviceType.File);
            rstDatabase.Devices.Add(bkpDevice);
            rstDatabase.ReplaceDatabase = true;
            rstDatabase.SqlRestore(sqlServer);
        }

   string saveAway = uiTBBackupDirectory.Text.Trim()+ "\\xxxx.bak";
                      string ConnectionString = ConfigurationManager.ConnectionStrings["SqlConnectionStr"].ToString();
                      string[] cons = ConnectionString.Split(';');
                      string[] databases = cons[3].Split('=');
   把上边的字符串划分字段改改整到下边的配置内,下边为测试数据

  SqlConnectionStringBuilder csb = new SqlConnectionStringBuilder();
                    csb.ConnectionString = ConnectionString;
                    csb.DataSource = ".,1933";
                    csb.InitialCatalog = "xxxx";
                    csb.UserID = "sa";
                    csb.Password = "125612";
                    bakHelper.BackupDatabase(csb,  saveAway);     

备份的路径必须写全了,连文件名也写进去,要不就会出现权限问题了.
