Add ( " Third " ); / / Remember, this is how you print all the items in a list strings . ForEach ( Console . WriteLine ); RemoveLast ( strings ); RemoveLast ( strings ); strings . ForEach ( Console . WriteLine );

Hi Mngaro Mwazenje, To remove the last value in the list you can use " RemoveAt " method as like following: public static void RemoveLast(List string > strings) { if (strings.Count > 0) strings.RemoveAt(strings.Count - 1); } For more detail https://www.dotnetperls.com/list-remove Hope, this will help you!

if (strings.Any()) //prevent IndexOutOfRangeException for empty list { rows.RemoveAt(rows.Count - 1); last index remove by function RemoveAt } or if (strings.Any()) //prevent IndexOutOfRangeException for empty list { var str = strings.last().last(); strings.Remove(str) //remove by value }
