New to Learn C# Programming

[sumityadav]

Hello all, I am learning C# programming, and last night I was writing code to find the sum of even numbers between 1 to n. here is my code:

using System;
class Program
{ 
    static void Main()
    {
        int[] numbers = { 1, 2, 8 };
        Console.WriteLine("\nArray1: [{0}]", string.Join(", ", numbers));
        var temp = numbers[0];
        for (var i = 0; i < numbers.Length - 1; i++)
        {
            numbers[i] = numbers[i + 1];
        }
        numbers[numbers.Length - 1] = temp;
        Console.WriteLine("\nAfter rotating array becomes: [{0}]", string.Join(", ", numbers));
 
        Console.ReadLine();
    }
 
}

While run the code, it shows an error, i do not understand it, can anyone please help me with this, taking some of the references from *** spammy link removed -- no actual code in the link pertinent to this question ***.

sum of even numbers

Doesn't appear to contain any code that performs the "even" part, or the "sum" part

It may be beyond you yet, but it can be done by:

  numbers.Sum(i=>i%2==0?i:0)

I think the OP was hoping that someone would just re write the code that has nothing to do with summing even numbers to actually do it.

Edit after: After following the link provided by the OP this looks to be more of a sophisticated spam post rather than a true programming question because the link was about popular C# interview questions, but the questions are actually more about C# concepts and facts (and the page has some facts wrong) rather than C# programming interview questions. Looks to be a away to drive up page views so that the claim on that page that it is "one of the most visited" sites eventually becomes true.

Hello, this is Gulshan Negi.
Well, in my opinion, there is no issue with your code; even I executed it, and it is working fine. If there is some issue, then please mention it in detail.
Thanks
