List<string>排序问题
现有一个需求，需要对List<string>里面的Ip进行排序，
例如，集合是这样的：

 List<string> IpList = new List<string>() {
            "172.16.88.220"
             +"222.73.29.77"
             +"192.168.1.8"
             +"172.16.88.2"
             +"192.168.1.7"
             +"172.16.88.10"
             +"172.16.88.3"
             +"172.16.88.8"
             +"172.16.88.225"
             +"172.16.88.100"
             +"221.130.187.180"
             +"221.130.187.181"
             +"222.73.55.168"
             +"172.16.88.7"
             +"222.73.29.79"
             +"172.16.88.200"
             +"172.16.88.125"
             +"192.168.1.1"
             +"222.73.55.250"
             +"115.236.102.216"
             +"172.17.22.161"
             +"222.73.29.135"
             +"222.73.29.136"
             +"172.17.22.162"
             +"172.16.88.9"
             +"115.238.26.184"
             +"115.238.26.185"
             +"115.238.26.186"
        };

最后想要的顺序是:
115.238.26.184
115.238.26.185
115.238.26.186
115.236.102.216
172.16.88.2
172.16.88.3
172......
192.168.1.1
192.168.1.7
192....
222.73.29.77
222...
请问大家这个如何实现？

,"172.17.22.161"
,"222.73.29.135"
,"222.73.29.136"
,"172.17.22.162"
,"172.16.88.9"
,"115.238.26.184"
,"115.238.26.185"
,"115.238.26.186"
,"115.238.102.216"
};
IpList.Sort((s1, s2) =>
{
string[] array1 = s1.Split('.');
string[] array2 = s2.Split('.');
int index = 0;
bool equal = true;
while (equal && index < 4)
{
equal = array1[index] == array2[index];
index++;
}
return int.Parse(array1[index - 1]).CompareTo(int.Parse(array2[index - 1]));
});
foreach (string ip in IpList)
Console.WriteLine(ip);


------解决方案--------------------

OJ的方法是可以的，在LINQ里同样也可以实现：

 
                                    ,"192.168.1.8"
                                    ,"172.16.88.2"
                                    ,"192.168.1.7"
                                    ,"172.16.88.10"
                                    ,"172.16.88.3"
                                    ,"172.16.88.8"
                                    ,"172.16.88.225"
                                    ,"172.16.88.100"
                                    ,"221.130.187.180"
                                    ,"221.130.187.181"
                                    ,"222.73.55.168"
                                    ,"172.16.88.7"
                                    ,"222.73.29.79" 
 
                                    ,"172.16.88.200"
                                    ,"172.16.88.125"
                                    ,"192.168.1.1"
                                    ,"222.73.55.250"
                                    ,"115.236.102.216"
                                    ,"172.17.22.161"
                                    ,"222.73.29.135"
                                    ,"222.73.29.136"
                                    ,"172.17.22.162"
                                    ,"172.16.88.9"
                                    ,"115.238.26.184"
                                    ,"115.238.26.185"
                                    ,"115.238.26.186"}; 
 
            var result = from x in IpList
                         let 补齐字符串 = string.Join(".", x.Split('.').Select(y => string.Format("{0:C3}", y)).ToArray())
                         orderby 补齐字符串
                         select x;
            foreach (var x in result)
                Console.WriteLine(x);
            Console.ReadKey();
        }

    }
