How to use transactions with a datacontext

Question

Can I use transactions with a datacontext, so that I can rollback the state of the context after an error? And if so, how does that work?

Answer 1

I use them in testing all the time :)

try
{
  dc.Connection.Open();
  dc.Transaction = dc.Connection.BeginTransaction();

  dc.SubmitChanges();
}
finally
{
  dc.Transaction.Rollback();
}

UPDATE

This will ALWAYS rollback after the fact. I use this in testing.
