create a transaction for MS Access in c#

Question

I need some code in my c# application to implement a transaction using Microsoft Access database

Answer 1

OleDbTransaction class is made just for that. You can create one by calling BeginTransaction on your OleDbConnection object then Commit or Rollback up to your scenario

using (var transaction = cn.BeginTransaction()) {
  //Do Stuff here using the connection
  transaction.Commit();
}

The transaction will be rolled back at dispose if no commit has been called.

Answer 2

Try to implement the code similar to the one below.

    public void InsertPersonAndPhoneNumber(int personId, string name, string phone)
    {
        string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=./contacts.accdb";
        OleDbConnection cn = new OleDbConnection(connectionString);
        try
        {
            cn.Open();
            OleDbTransaction trans = cn.BeginTransaction();
            try
            {
                //first transaction ...
                string sql1 = "INSERT INTO People (ID, pname) VALUES (@ID, @pname)";
                OleDbCommand cmd1 = new OleDbCommand(sql1, cn, trans);
                cmd1.Parameters.AddWithValue("@ID", personId);
                cmd1.Parameters.AddWithValue("@pname", name);
                cmd1.ExecuteNonQuery();

                //first transaction ...
                string sql2 = "INSERT INTO PhoneNumbers (PID, num) VALUES (@PID, @num)";
                OleDbCommand cmd2 = new OleDbCommand(sql2, cn, trans);
                cmd2.Parameters.AddWithValue("@PID", personId);
                cmd2.Parameters.AddWithValue("@num", phone);
                cmd2.ExecuteNonQuery();

                trans.Commit();
                Console.WriteLine("New Contact Added successfully ...");

            }
            catch (Exception x)
            {
                //handle exception .... 
                trans.Rollback();
                Console.WriteLine(x.Message);
            }
            finally
            {
                cn.Close();
            }
        }
        catch (Exception x)
        {
            //handle exception .... 

        }

    }
