问题描述

如何:在记录上创建日期限制?

how to:creating date limitation on logging?

推荐答案

假设您知道一般如何进行授权，而您的问题只是时间，这就是答案:使用类型System.DateTime.您可以使用静态方法System.DateTime.Now或System.DateTime.UtcNow(在您的应用程序服务于多个时区时很好)来获取当前时间.为了进行比较，只需使用运算符"=="，！="，<"，>"，< ="和> =".对于您的所有目的，这应该足够了.

Assuming you know how to do authorization in general and your problem is only the timing, here is the answer: use the type System.DateTime. You can get current time using the static method System.DateTime.Now or System.DateTime.UtcNow (which is good when your application serves multiple time zones). For comparison, simply use operators "==", "!=", "<", ">", "<=" and ">=". That should be enough for all your purposes.
