    sqCommand.ExecuteNonQuery();
    sqConnection.Commit();
    Console.WriteLine("Both records are written to database.");

  catch(Exception e)
  {
    sqConnection.Rollback();
    Console.WriteLine(e.ToString());
    Console.WriteLine("Neither record was written to database.");
  }
  finally
  {
    sqConnection.Close();
  }
}

Visual Basic

Public Sub RunSQLiteTransaction(myConnString As String)
  Dim sqConnection As New SQLiteConnection(myConnString)
  sqConnection.Open()
  Dim sqCommand As New SQLiteCommand()
  sqCommand.Connection = sqConnection
  sqConnection.BeginTransaction()
  Try
    sqCommand.CommandText = "INSERT INTO Dept(DeptNo, DName) Values(50, 'DEVELOPMENT')"
    sqCommand.ExecuteNonQuery()
    sqCommand.CommandText = "INSERT INTO Dept(DeptNo, DName) Values(60, 'PRODUCTION')"
    sqCommand.ExecuteNonQuery()
    sqConnection.Commit()
    Console.WriteLine("Both records are written to database.")
  Catch e As Exception
    sqConnection.Rollback()
    Console.WriteLine(e.ToString())
    Console.WriteLine("Neither record was written to database.")
  Finally
    sqConnection.Close()
  End Try
End Sub
