Casting types inline

I'm still not clear on all the routes to this, and which one is best for readability. I'm trying to get

.Count

.Count

from a child object of

object sender

object sender

. The Type hierarchy is:

DirectDragTreeViewItem.GistViewModel.GistModel.IList<GistFileModel>

DirectDragTreeViewItem.GistViewModel.GistModel.IList<GistFileModel>

Here are a couple of ways I've tried:

int directCastListCount = (GistViewModel)((DirectDragTreeViewItem)sender).DataContext) // wtf!? gave up here
int paternMatchedListCount = ((((sender as DirectDragTreeViewItem).DataContext as GistViewModel).Gist as GistModel).Files as IList<GistFileModel>).Count();

int directCastListCount = (GistViewModel)((DirectDragTreeViewItem)sender).DataContext) // wtf!? gave up here
int paternMatchedListCount = ((((sender as DirectDragTreeViewItem).DataContext as GistViewModel).Gist as GistModel).Files as IList<GistFileModel>).Count();

Of course things could be nested deeper. Which is the best way (realise 'best' is ambiguous)

send proper event args

What are you trying to achieve here? What's the purpose of this code?
If you want to pass data with event you don't need the sender object but
Also casting here looks strange to me...

I was really asking more conceptually

Joreyk ( IXLLEGACYIXL )•4/4/24, 8:08 PM

in C# you have always ( atleast in Gui its standard ) for an event of some kind
you define the ImportantEventArgs yourself, and there you put your types accurately how you need them into that

you shouldnt cast the sender

Stefanidze•4/4/24, 8:08 PM

Well, if you want this code working, this looks fine to me:

But you really shouldn't do this to pass data with events...

Yeah - I'm jjst tinkering with someone else's code + i hear what you are saying about design, but my question was really about syntax/concepts

Joreyk ( IXLLEGACYIXL )•4/4/24, 8:57 PM

the concept is to not do what has be done
