Custom Class used as key in Dictionary but key not found

Question

I have a class, show below, which is used as a key in a Dictionary I\'m having issues when trying to find any key within this diction

Answer 1

I had this problem, turns out the dictionary was comparing referances for my key, not the values in the object.

I was using a custom Point class as keys. I overrode the ToString() and the GetHashCode() methods and viola, key lookup worked fine.
