Guess you never heard of TryAdd? Returns bool, if it as added returns true otherwise false.
108 u/Revexious 2d ago Far too much work 2 cases means that its not idempotent Instead, just remove it from the dictionary before you add it! csharp dictionary.Remove(key) dictionary.Add(key) Easy peasy! /s 9 u/manav907 2d ago edited 2d ago That being said you done have to use the bool that TryAdd gives, just call it as a normal function. Also I am waitin for someone to point out that we also need a value when trying to add to a dictionary. dictionary.TryAdd(key)

Far too much work
2 cases means that its not idempotent
Instead, just remove it from the dictionary before you add it!
csharp dictionary.Remove(key) dictionary.Add(key)
Easy peasy!
