Question

I have a class which contains multiple properties of type Int32:

public class MyClass
{
    public int C1 { get; set; }
    public int C2 { get; set; }
    public int C3 { get; set; }
    .
    .
    .
    public int Cn { get; set; }
}

I want to sum all this properties. Instead of doing:

int sum = C1 + C2 + C3 + ... + Cn

is there a more efficient/elegant method?

You can fake it, but I’m not sure how useful it is:

using System;
using System.Collections.Generic;
using System.Linq;

namespace Demo
{
    class Program
    {
        static void Main(string[] args)
        {
            var test = new MyClass();
            // ...
            int sum = test.All().Sum();
        }
    }

    public class MyClass
    {
        public int C1 { get; set; }
        public int C2 { get; set; }
        public int C3 { get; set; }
        // ...
        public int Cn { get; set; }

        public IEnumerable<int> All()
        {
            yield return C1; 
            yield return C2; 
            yield return C3; 
            // ...
            yield return Cn; 
        }
    }
}
