How can I find the last element in a List<>?

If you just want to access the last item in the list you can do

if (integerList.Count > 0)
{
   //  pre C#8.0 : var item = integerList[integerList.Count - 1];
   //  C#8.0 : 
   var item = integerList[^1];
}

to get the total number of items in the list you can use the Count property

var itemCount = integerList.Count;

In C# 8.0 you can get the last item with ^ operator full explanation

List<char> list = ...;
var value = list[^1]; 

// Gets translated to 
var value = list[list.Count - 1];

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

var lastItem = integerList.LastOrDefault();

var lastItem = integerList.Last();

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