推荐答案

您严重找不到此 ^ ]

You seriously couldn''t find this String.IndexOf[^]

由于，Email 地址的Local 部分和Domain 部分中允许使用.s ，如此处所述
http://en.wikipedia.org/wiki/Email_address#Valid_email_addresses [

Since, .s are allowed inside the Local part and Domain part of Email address as explained here
http://en.wikipedia.org/wiki/Email_address#Valid_email_addresses[^]
the following statement can be used to extract the domain name

string emailAddress = @"[e-mail]";
string domainName = emailAddress.Substring(emailAddress.IndexOf('.',emailAddress.LastIndexOf('@')));
Console.WriteLine (domainName);

//.co.in

如果仅在此处说明顶级域名
http://en.wikipedia.org/wiki/Domain_Name [

If only the top level domain name explained here
http://en.wikipedia.org/wiki/Domain_Name[^] is required then

string domainName = emailAddress.Substring(emailAddress.LastIndexOf('.'));
Console.WriteLine (domainName);

//.in

可以使用.

can be used.
