c# ERROR : The modifier 'private ' is not valid for this item

Question

It doesn't matter what modifier I put on the front of the function(I've tried with public, private and even protected), I always receive an error, the same error. The code is clean only after I delete the modifier and I left the function "Array()" without one. Can someone look at my code and explain to me what is happening please, I am new to c#, and also new to asking help, so please excuse every mistake I've made so far.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp2
{
    class Program
    {
        static void Main(string[] args)
        {

            public void Array()//nu se pune in interiorul functiei void Main (), deoarece va forma nesting, si ne va da eroare la compilare.
            {
                int[] intArray;
                intArray = new int[3];//all values will be 3


                var doubleArray = new[] { 34.23, 10.2, 23.2 };

                //var arrayElement = doubleArray[0];
                //doubleArray[1] = 5.55;

                for (var i = 0; i < intArray.Length; i++)
                {
                    Console.WriteLine(intArray[i]);
                }
            }

        }



    }
}

I've posted the code and the image of it down below.

In this image you can see the code

Please don't post images of code, add the actual code to your question. — DavidG, Mar 13 '19 at 16:02
@DavidG I wish I could do it , but I don't know how. When I wanted to paste the code, it only allowed html , css and javascript languages. I tried to change the language and it required me the URL adress of the place of the code, but I don't have my code on a site and I don't know if I can put it on one. — Corina, Mar 13 '19 at 16:06
There is nothing to stop you pasting the code directly into the window, then make sure you press the "Code sample" button to format it. — DavidG, Mar 13 '19 at 16:07

You have a nested function, in C# these are called local functions and don't have scope. so you need to remove the access modifier, for example:

public static void PrintHelloWorld()
{
    string GetName()
    {
        return "world";
    }


    Console.WriteLine($"Hello {GetName()}");
}

You are creating a nested method (also called local function). Nested methods may not have access modifiers. They are only accessible from within this method.

For reference: https://learn.microsoft.com/dotnet/csharp/programming-guide/classes-and-structs/local-functions

You are putting your private function inside a static function. Remove the private.

It *is* allowed in C# 7. Not my downvote btw – Panagiotis Kanavos Mar 13 '19 at 16:03
ok, I will adjust... – T McKeown Mar 13 '19 at 16:03
Not sure why you mention static here, it's not relevant at all. Also, you don't really explain why removing private is helpful. – DavidG Mar 13 '19 at 16:15
I probably should be shot... – T McKeown Mar 13 '19 at 16:17
my comment stated EXACTLY what the OP was doing btw... – T McKeown Mar 13 '19 at 16:17
No need to get so defensive, I'm just saying what I think can be improved. – DavidG Mar 13 '19 at 16:18

Move the function out of the Main function. Also you should mark it as static and then use it as you intend. This in case you don't want a nested method as it is already answered.
