Question

我有一个字符串表，例如：

string[] list = { "900 google.mail.com", "50 yahoo.com", "1 intel.mail.com", "5 wiki.org" };

string delimiter = ".";
foreach (var item in cpdomains)
{
    var result = item.Split(' ', '.').Aggregate((a,b) => a + delimiter +b);
    result.ForEach(e => Console.WriteLine(e));
    Console.WriteLine(result);        
}

我现在的结果

900.google.mail.com
50.yahoo.com
1.intel.mail.com
5.wiki.org

我想将每个字符串分成这样的子字符串：

1- 900
2- google.mail.com
3-mail.com
4-com
etc...

我该怎么做？预先感谢

Answer 1

    public string[] GetParentDomains(string[] input) {
    return input
        .SelectMany(s => s.Split(' '))
        .SelectMany(s => {
                    string[] splitDomain = s.Split('.');
                    return  Enumerable.Range(0, splitDomain.Length)
                        .Select(counter => 
                                String.Join(".", splitDomain.Skip(counter)))
                        .ToArray(); 
                   })
        .ToArray();              
}

输出

900
google.mail.com
mail.com
com
50
yahoo.com
com
1
intel.mail.com
mail.com
com
5
wiki.org
org

LINQ使用定界符将字符串顺序拆分为子字符串
