Is there any way to get all user friend using Skype with C#?
Also how can I get active(online friends).

first you must add a reference at SKYPE4COMLib from the COM reference tab on your project, then make sure that your apllication will be builded as x86 finally try to use this code snippet:

using System;
using System.Collections.Generic;
using System.Linq;
using SKYPE4COMLib;

namespace Example
{
    class SkypeExample
    {
        static void Main(string[] args)
        {
            SkypeClass _skype = new SkypeClass();
            _skype.Attach(7, false);

            IEnumerable<SKYPE4COMLib.User> users = _skype.Friends.OfType<SKYPE4COMLib.User>();

            users
                .Where(u => u.OnlineStatus == TOnlineStatus.olsOnline)
                .OrderBy(u => u.FullName)
                .ToList()
                .ForEach(u => Console.WriteLine("'{0}' is an online friend.", u.FullName));

            Console.ReadKey();
        }
    }
}

Hope this helps.
