I have a WinForms application that interacts with a SqlCe local database. I manage db operations using BindingSources, TableAdapters and typed datasets.I have several operations scattered through several methods in two different classes that I need to perform in a transaction and I was thinking of using System.Transactions.Transaction or CommitableTransaction. My question is, would Transaction or CommittableTransaction work successfully in a transaction and rollback in an error in this example code or do I have to also use transaction in OtherClass methods too?:
OtherClass othercls = new OtherClass();
...
private void DoAll()
{
/* begin transaction here */
this.tableAdapter.DoSomeDBWork();
othercls.DeleteSomeRecords(); //uses tableadapter+sql code to delete. throws exception on error. doesn't have transaction
othercls.DeletOtherRecords(); //uses tableAdapter.Rows.Find(id).Delete(). throws exception on error. doesn't have transaction
othercls.Update(); //uses tableadapter.Update(). throws exception on error. doesn't have transaction
this.DeleteSomeFiles(); //throws exception on fail
/* end transaction here */
}
