Sort two Lists together as one?

Question

I have two List which I am accessing by index (e.g. Name[10], Date[10]). They\'re closely tied, so Name[10] is related to Date[1

Answer 1

You could create a custom type to hold a value, or if you only need to use it in the scope of a single method you could use an anonymous type as follows.

var namesAndDates = MyNames
    .Select((name, i) => new {name, date = MyDates[i]});

From here the two values are no longer loosely tied. Now you can sort them.

var sortedNamesAndDates = namesAndDates.OrderBy(a => a.date);

Or whatever else you'll need to do with them.
