I have read this in answer to many questions on here. But what exactly does it mean?
var test = new Dictionary<int, string>();
test.Add(0, "zero");
test.Add(1, "one");
test.Add(2, "two");
test.Add(3, "three");
Assert(test.ElementAt(2).Value == "two");
The above code seems to work as expected. So in what manner is a dictionary considered unordered? Under what circumstances could the above code fail?
