推荐答案

我认为Uri 类可用于从url 字符串中提取Host 名称，它可以拆分''.''和第一个与豁免字符串不匹配的单词可以如下所示

I think the Uri class can be used to extract the Host name from the url string, it can be split up with ''.'' and the first word which does not match the exempted strings can be taken as shown below

string[] urls = {@"https://WWW.facebook.com/pages/Delhi/Shemrock-Chain-of-Preschools/359534360364",
        @"http://twitter.com/#!/ShemrockGroup",
        @"http://www.youtube.com/user/shemrocknurseryrhyme"};

foreach(string url in urls)
//"www mail"  etc. to exclude the intial parts not required.
    Console.WriteLine (((new Uri(url)).Host).Split('.')
        .FirstOrDefault(str => !@"www mail".Contains(str.ToLower())) ?? string.Empty);

//Output
//
//facebook
//twitter
//youtube
