Tuples as key in Dictionary

[azhahes]

Is Dictionary<(int , int ), int> and Dictionary<Tuple<int , int>, int> are same?

They are not exactly the same thing.

Right now, the above feels like a question that would be part of set of screening questions for an interview to make sure that you know C#.

If it's not part of an interview, what have you tried? What does your compiler tell you?

No, there was a scenario to use two values as keys, so tried Tuple. I thought of trying different syntax of tuple so tried like this Dictionary<(int, int ), int> and it worked. Both methods give the same result. So I just want to know how it differs and When to go for tuple and when to go for (int i, int j).
