If you want just a simple reader without sections and any other dlls here is simple solution:

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

namespace Tool
{
    public class Config
    {
        Dictionary  values;
        public Config (string path)
        {
            values = File.ReadLines(path)
            .Where(line => (!String.IsNullOrWhiteSpace(line) && !line.StartsWith("#")))
            .Select(line => line.Split(new char[] { '=' }, 2, 0))
            .ToDictionary(parts => parts[0].Trim(), parts => parts.Length>1?parts[1].Trim():null);
        }
        public string Value (string name, string value=null)
        {
            if (values!=null && values.ContainsKey(name))
            {
                return values[name];
            }
            return value;
        }
    }
}

Usage sample:

    file = new Tool.Config (Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\config.ini");
    command = file.Value ("command");
    action = file.Value ("action");
    string value;
    //second parameter is default value if no key found with this name
    value = file.Value("debug","true");
    this.debug = (value.ToLower()=="true" || value== "1");
    value = file.Value("plain", "false");
    this.plain = (value.ToLower() == "true" || value == "1");

Config file content meanwhile (as you see supports # symbol for line comment):

#command to run
command = php

#default script
action = index.php

#debug mode
#debug = true

#plain text mode
#plain = false

#icon = favico.ico
