用于电子邮件的正则表达式无法验证高级域中的数字

Question

 private const string EmailPattern = @"\A(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?)\Z";

I am able to validate most of the emails correctly but one of the condition that I want to validated is numeric digit at the end of the high level domain. eg : abc@test.com1 (I dont think this is a valid email and want to validate this condition)

There are lot of regex tht I have tried but no success.

Answer 1

试试这个正则表达式

^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$
