Question

I want to declare a tuple that contains a boolean and a list of longs.

This is what I have but it’s underlined red on the last List:

Tuple<bool, List<long>> TheTuple = new Tuple<bool,List<long>>(false, List<long>);

What am I missing?

Thanks.

Answer 1

Tuple<bool, List<long>> TheTuple = Tuple.Create(false, default(List<long>));

Note that it will set the Item2 property of the tuple to null, which is perhaps not what you want. If you want to set it to an actual List<long>, use new List<long>():

Tuple<bool, List<long>> TheTuple = Tuple.Create(false, new List<long>());
