If there is only one thread accessing the hashtable, nothing can be removed/added at the exact same time you're looping through it.

I posted in another thread how to use Singleton with standard lock plus double-check on hashtables and it works perfectly.

i believe it was in thread haydz made on how to make a hashtable or something i forget.

tw3ak give me a link ,or what should i search to find it?

Search for threads started by Haydz, the one about hashtables

lemme look

Ok... So I think I'm understanding this a bit better. Still don't want to jump into the lock procedure just incase. From what I gather. This line in itself is what accesses the hashtable.

for

I ran through my character.cs to find over 20 sections involving that one hashtable. Information revolving around damage dealt, lvling up, mobs, NPC's, skills, etc...

Now I know you guys said it's best to have seperate hashtables for each task correect? Excuse me if I'm wrong, so much reading, it's hard to keep track of everything. But in such a case, could I merely create new hashtables for each individual action, and if so, would this require any changes elsewhere?

Any insight is appreciated, and I apologize for being a pain in the ass, I just don't want to take any durastic measures unless needed. And on my time schedule the past day or two, it's hard for me to really dive into tons of reading all at once, so it's hard to make sense of it when only taking partial info every so often.

You could queue hashtable loops so they execute on one thread dequeuing them, or you could do what I do, avoid the hashtable class all together unless you know it won't be accessed on two threads at the same time in a loop.
