Thread safety with Dictionary in .Net

Question

I have this function:

static Dictionary KeyValueDictionary = new Dictionary();
static void IncreaseValue(int keyId, int adj         


        

Answer 1

It's not thread safe, but does not check and so probably doesn't notice silent corruption.

It will appear to be thread safe for a long time because only when it needs to rehash() does it have even a chance of exception. Otherwise, it just corrupts data.
