Count is zero after assigning to List

Question

I have the following code in my program:

List<_Transaction> transactionListing = collectionRun.AttachedTransactions;

When I debug, the AttachedTransactions hsa a count of 3 (its also a list of List<_Transaction>). But the assignment does not work because the transactionListing has a count of zero. I'm perplexed.

EDIT: On the right hand side the count of AttachedTransactions is 3. But on the left hand side the count of transactionListing remains zero after assignment

Answer 1

Try this:

List<_Transaction> transactionListing = collectionRun.AttachedTransactions.ToList();

Or:

List<_Transaction> transactionListing = new List<_Transaction>(collectionRun.AttachedTransactions);

This will make a copy of the AttachedTransactions list at the time of assignment.

At the moment you're getting a reference to collectionRun.AttachedTransactions and I'm guessing that something else is altering it so it appears that the assignment isn't working.
