普通防爆pression从电子邮件地址域 [英] Regular Expression for domain from email address
问题描述
谁能帮我一个普通的EX pression将返回一个电子邮件地址的末端部分，@符号后？我是新来的正则表达式，但想学习如何使用它，而不是写低效的.Net字符串函数！
Can anyone help me with a regular expression that will return the end part of an email address, after the @ symbol? I'm new to regex, but want to learn how to use it rather than writing inefficient .Net string functions!
例如。对于test@example.com的输入，我需要的输出example.com。
E.g. for an input of "test@example.com" I need an output of "example.com".
干杯！ 蒂姆·
推荐答案
一个普通EX pression是相当重机用于这一目的。刚刚拆分包含在的电子邮件地址@ 字符的字符串，并采取了下半场。 （电子邮件地址是保证只包含一个 @ 字符。）
A regular expression is quite heavy machinery for this purpose. Just split the string containing the email address at the @ character, and take the second half. (An email address is guaranteed to contain only one @ character.)
