How to use a list in functions outside main?

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

namespace Lazo
{
    class Program
    {
        List<string> L = new List<string>();
        static void Main(string[] args)
        {
            //List<string> L = new List<string>();
            L.Add("L");
            L.Add("A");
            L.Add("Z");
            L.Add("O");

            izbrisiElement("test");
        }

        static void izbrisiElement(string element_brisi)
        {
            for (int i = 0; i < L.Count - 1; i++)
            {
                if (L[i] == element_brisi)
                {
                    //do something
                }
            }
        }
    }
}

I want to use the list created in main in other functions outside main. I have tried inside main and outside main, but none works. I'm not exactly sure where my mistake is. Could anyone help me out?

Main method is static, it means it doesn't belong to any instance, but you are declaring your list as an instance field.So when you access it in a method it means you are trying to access the member of the current instance in other words: this.L, but this doesn't exist in the static context.

You need to make it static:

static List<string> L = new List<string>();

You should declare it as static:

static List<string> L = new List<string>();

in order to be used from your static methods.
