Converting an array to a list of integers

Next, enter the following below this line:

List<int> lst = new int[] { 1, 2, 12, 4, 5, -10, 5, 25, 54 }.ToList();

To make a list of integers, we say lst = new int[]. Then we specify the initializer list and the values shown here. It doesn't matter what values you use. I'll show you some of the methods. Of course, as you can imagine, there are many of them.

Now, note that you could not stop writing this line after the array. If you did, the pop-up tip would say Cannot implicitly convert type 'int[]' System.Collections.Generic.List<int>'; so you have to add .ToList(). You can convert an array to a list of integers.
