推荐答案

从用户那里读取密码到期日期。将其转换为DateTime值。

使用DateTime.Now获取当前日期。使用AddMonths添加六个月。

比较两个日期。如果有效期最长，那很好。如果不是，它就不会持续足够长的时间。



这是你的作业，所以我不会给你任何代码！除了我？我是用JavaScript做的，而不是强行往返服务器。

Read the password expiry date from the user. Convert it to a DateTime value.
Get the current date using DateTime.Now. Add six months using AddMonths.
Compare the two dates. If the expiry date is the greatest, it's fine. If it isn't, it doesn't last long enough.

This is your homework, so I'll give you no code! But me? I'd do it in JavaScript rather than force a round trip to the server.

.validator.addMethod（ expiryValidator，function（value，element）{
var val = Date.parse（value）;
if（isNaN（val））
return false;

var d = new Date（val）;
var f = new Date（）;

f.setMonth（f.getMonth（）+ 6）;
if（d < f）{
返回false;
}

返回true;
}）;

.validator.addMethod("expiryValidator", function (value, element) { var val = Date.parse(value); if (isNaN(val)) return false; var d = new Date(val); var f = new Date(); f.setMonth(f.getMonth() + 6); if (d < f) { return false; } return true; });
