How can I assign 1 to the last element of an array?

Question

I used Last(),but there were a lot of errors

Answer 1

To get the last item of a collection use LastOrDefault() and Last() extension methods

var lastItem = integerList.LastOrDefault();

OR

var lastItem = integerList.Last();

Remeber to add using System.Linq;, or this method won't be available.

may by using that your problem will solved
