使用 C# 代码备份失败

Question

我的问题是我无法使用 C# 代码在 wpf 中备份我的数据库。错误是“服务器 'DELL/LOCALSERVER' 的备份失败”。我使用的代码是这样的：

private void btnBackup_Click(object sender, RoutedEventArgs e)

{
  if (!string.IsNullOrEmpty(txtPath.Text) && !string.IsNullOrWhiteSpace(txtPath.Text)
    && !string.IsNullOrEmpty(txtFileName.Text) && !string.IsNullOrWhiteSpace(txtFileName.Text))
  {
    BackupFilePath = txtPath.Text + "" + txtFileName.Text + ".bak";
    Server sqlServerInstance = new Server(new Microsoft.SqlServer.Management.Common.ServerConnection
      (new System.Data.SqlClient.SqlConnection(h2prdb.ConnectionString)));
    Backup objBackup = new Backup();
    objBackup.Database = "H2RPDB";
    objBackup.Action = BackupActionType.Database;
    objBackup.Devices.AddDevice(@BackupFilePath, DeviceType.File);
    objBackup.SqlBackup(sqlServerInstance);
    System.Windows.Forms.MessageBox.Show("The backup of database " + "'H2RPDB'" + " completed sccessfully", "Microsoft SQL Server Management Studio", MessageBoxButtons.OK, MessageBoxIcon.Information);
  }
  else
  {
    System.Windows.Forms.MessageBox.Show("Please fill-up all fields!",
      "Backup/Restore", MessageBoxButtons.OK, MessageBoxIcon.Warning);
  }
}

我不知道对这段代码不熟悉有什么问题。感谢您的回答。

你可以使用下面提到的代码

            ServerConnection con = new ServerConnection(@"ServerName");
            Server server = new Server(con);
            Backup source = new Backup();
            source.Action = BackupActionType.Database;
            source.Database = "DBName";
            BackupDeviceItem destination = new BackupDeviceItem(@"C:\tmp\temp.bak", DeviceType.File);
            source.Devices.Add(destination);
            source.SqlBackup(server);
            con.Disconnect();

确保您以管理员身份打开了 Visual Studio。 并且您必须包含下面提到的参考以运行上述代码

Microsoft.SqlServer.ConnectionInfo.dll
Microsoft.SqlServer.Management.Sdk.Sfc.dll
Microsoft.SqlServer.Smo.dll
Microsoft.SqlServer.SmoExtended.dll

您可以在C:\Program Files\Microsoft SQL Server\110\SDK\Assemblies 上找到所有上述 DLL
