Hi i am trying to make my own little config reader for my programs I got most of it working but i am haveing troble trying to return a list from a class, evey time i type the class name the list function does not show up in the list eveything else works fine, I left my class code here so maybe someone can see what i am doing wrong thanks.

Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace TestConfig{

    public class MyConfig
    {
        private string _Filename;
        private static Dictionary<string, string> Lines = new Dictionary<string, string>();

        public MyConfig(string localname)
        {
            this._Filename = localname;
            string sLine;
            int cnt = 0;
            //Check if file is here

            if (!File.Exists(localname))
            {
                throw new FileNotFoundException("File Not Found:\n" + this._Filename);
            }
            else
            {
                using (StreamReader sr = new StreamReader(this._Filename))
                {
                    while (!sr.EndOfStream)
                    {
                        sLine = sr.ReadLine().Trim();
                        //Check for comments
                        if (sLine.StartsWith("//"))
                        {
                            cnt++;
                            Lines.Add(cnt.ToString(), sLine);
                        }
                        else
                        {
                            //Get position of space
                            int spos = sLine.IndexOf(" ");
                            //Check for space position
                            if (spos != -1)
                            {
                                //Extract key
                                string sKey = sLine.Substring(0, spos).ToLower();
                                //Extract value
                                string sValue = sLine.Substring(spos + 1, sLine.Length - spos - 1);
                                //Add to the dir
                                Lines.Add(sKey, sValue);
                            }
                        }
                    }
                }
            }
        }

        public static List<string> Keys()
        {
            List<string> items = new List<string>();
            items.AddRange(Lines.Keys);
            return items;
        }

        public string ReadValue(string keyname)
        {
            try
            {
                return Lines[keyname];
            }
            catch
            {
                return "";
            }
