How to asynchronously run multiple methods in C#

Answer 1

using System;
using System.Threading.Tasks;

class Program
{
    static void Main()
    {
        // Call async method 13 times.
        for (int i = 0; i < 13; i++) {
            RunMethods(i);
        }
        Console.ReadLine();
    }
    
    static async void RunMethods(int val) {
        int result = await Task.Run(() => Calc(val))
                    .ContinueWith(task => Plus10000(task));
        Console.WriteLine("RunMethods result: " + result);
    }
    
    static int Calc(int val) {
        int sum = 0;
        for (int i = 0; i < val; i++) {
            sum += (int)Math.Pow(i, 2);
        }
        return sum;
    }
    
    static int Plus10000(Task<int> task) {
        return task.Result + 10000;
    }
}
