I have several string collections in my C# project that are stored in Settings. At the beginning of this project, I had initialized these collections to contain 20 values, all being 0s. Lately I've realised I actually need about 100 0s in each collection so I went and added 80 more to each collection. This working fine but now I'm seeing strange things.
I was getting an out of bounded range exception and when I followed it back it came to trying to access an item at the index of 20 in one of my string collections. Hmm. That shouldn't be the case so I go to check my stringCollection that is apparently too small to handle an index of 20 and sure enough still all 100 of my 0s are still there. So then at the breakpoint I hover over my string collection and it says .count = 20. WHAT? I can literally see 100 0s here in the settings.settings file. I counted okay?
So then I went and deleted that string collection, made a new one with the SAME name and SAME contents and it's fine. But I don't want to have to go and redo this for EVERY string collection I have in my settings.
Has anyone come across this? Is it a bug? Why is it that if I delete the collection and then remake it, it suddenly works?
