asp.Net TransactionScope error

whenever I put TransactionScope, I got this error.

ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.

   using (TransactionScope scope = new TransactionScope())
   {

        ptDA.UpdateTC(InboundDS);
        ptDA.Addinventor(InboundDS);
        addressDA.AddAddress(InboundDS);
        scope.Complete();
  }

If I don't put the transaction scope , I don't get any error. This one runs well.

        ptDA.UpdateTC(InboundDS);
        ptDA.Addinventor(InboundDS);
        addressDA.AddAddress(InboundDS);

What's wrong with my transactionScope?

回答1:

Try opening your connection within the TransactionScope.
