推荐答案

您可以在代码中写条件来检查日期





试试这个

You can write condition within your code to check the date


try this

if (yourdate <=DateTime.Now && yourdate >=DateTime.Now.AddDays(-7))
            {
                
            }

check DateTime.Today Property（System） [ ^ ]和DateTime.AddDays Method（Double）（System） [ ^ ]

您需要将给定日期与DateTime.Today和7天后的日期进行比较。具有减值参数的DateTime.AddDays方法将减少从给定日期开始的天数，因此您可以使用它来查找日期前7天。除此之外，你需要C＃如果条件。试试自己。

check DateTime.Today Property (System)[^] and DateTime.AddDays Method (Double) (System)[^]
You need to compare given date with DateTime.Today and Date in 7 days back. DateTime.AddDays method with minus value parameter will reduce the days from given date, so you can use that to find 7 days before date. other than that you need C# if conditions. Try yourself.

学习比较和日期时间值的算术运算 [ ^ ]
