How to get first N elements of a list in C#?



I would like to use Linq to query a bus schedule in my project, so that at any time I can get the next 5 bus arrival times. How can I limit my query to the first 5 results?

More generally, how can I take a slice of a list in C#? (In Python I would use mylist[:5] to get the first 5 elements.)

Accepted Answer

var firstFiveItems = myList.Take(5);

Or to slice:

var secondFiveItems = myList.Skip(5).Take(5);

And of course often it's convenient to get the first five items according to some kind of order:

var firstFiveArrivals = myList.OrderBy(i => i.ArrivalTime).Take(5);

In case anyone is interested (even if the question does not ask for this version), in C# 2 would be: (I have edited the answer, following some suggestions)

List<string> fiveElements = myList.GetRange(0, 5);
