Solution 2

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.

Solution 3

You can write condition within your code to check the date

try this

C#

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