Task.WhenAll return list instead of array

Question

I try to find a solution of this but I didn't able to find it. That's why I'm asking here. :)

I'm having a list of tasks and It has two items

List<Task<int>> tasks = new List<Task<int>>();
     tasks.Add(Task.FromResult(1));
          tasks.Add(Task.FromResult(2));

When I call await Task.WhenAll(tasks), it returns int[] but I want it should return List<int>. Like below:

List<int> result = await Task.WhenAll(tasks);

I want to add new item in the list after I've the result.

You can write:

List<int> result = (await Task.WhenAll(tasks)).ToList();

This will convert the array to a list.

Do not forget to add the namespace:

using System.Linq;
