C# 中 List.Sort运用(IComparer<T>)排序用法

        /// <summary>
        /// 比较人物类实例大小,实现接口IComparer
        /// </summary>
        public class InternetProtocolComparer : IComparer<InternetProtocol>
        {
            public int Compare(InternetProtocol x, InternetProtocol y)
            {
                if (x == null)
                {
                    if (y == null)
                        return 0;
                    else
                        return -1;
                }
                else
                {
                    if (y == null)
                        return 1;
                    else
                    {

  

              if (string.IsNullOrWhiteSpace(x.IP) || string.IsNullOrWhiteSpace(y.IP))
                return 0;

                        int xIP = int.Parse(x.IP.Replace(".", ""));
                        int yIP = int.Parse(y.IP.Replace(".", ""));

                        int retval = yIP.CompareTo(xIP);

                        return retval;
                    
                    }
                }
            }
        }
