Question

I’m running the following code:

 hashedUrlDataList.Select(mDalHashedUrlData.Save);

I have put a breakpoint in the called delegate,

public HashedUrlData Save(HashedUrlData item)
    {
//breakpoint here 
           }

but it doesn’t stop there.

How can I fix this?

Answer 1

Enumerable.Select is Lazy.
Try this and tell me if your break point is caught

hashedUrlDataList.Select(mDalHashedUrlData.Save).ToList();

Or the basic:

hashedUrlDataList.Select(mDalHashedUrlData.Save).GetEnumerator().MoveNext()

It just works if you have at least one element.

You can do it too:

    hashedUrlDataList.Select(mDalHashedUrlData.Save).Any();

Any() do the same that GetEnumerator().MoveNext()

I think that what you want is:

List<HashedUrlData> hashedUrlDataList = new List<HashedUrlData>();
hashedUrlDataList.ForEach(Save);
