Question

I use dataset’ Insert() method to insert data to database.Like:

 public void InsertData()
 {
    ATableAdapter a = new ATableAdapter();
    a.Insert(//some parameters);  //step 1: OK
    BTableAdapter b = new BTableAdapter();
    b.Insert(//some parameters); //step 2: throw exception
    ....
 }

When running step 2, the program throws a exception and stop running the following functions,
but in database, there is a dummy record that generated in step 1,
how can i avoid that?

Answer 1

Wrap both steps in a Transaction.

See TransactionScope.

You will need to enlist the commands in the transaction.
