推荐答案

使用 ^ ].
尝试使用\w+([_.]\w+)*@\w+([-]\w+)*\.\w+([-.]\w+)*表达式，或根据您的约束对其进行修改.

Use RegularEexpressionValidator[^].
Try \w+([_.]\w+)*@\w+([-]\w+)*\.\w+([-.]\w+)* expression, or modify it as per your constraints.

就真实而言，您永远无法判断地址是否有效".正如其他人所说，您可以使用正则表达式查看其格式是否正确.这就是网站向人们发送链接以进行确认的原因，这是做到这一点的唯一方法.

ASP和ASP.NET是两个不同的东西.

You cannot EVER tell if an address is ''valid'' in terms of being real. You can use regex to see if it is well formed, as others have said. That''s why sites send people a link to confirm, that''s the only way to do it.

ASP and ASP.NET are two different things.
