hide image in 3 days

Question

hello,

 

how do i do to hide image in 3 days. I use start date using Datetime.Now. e.g: my start date is 6/9/2016, after 3 days starts from 6/9/2016 an image will hide.Meaning that at 10/9/2016 the image must hide. below are my example code that did not have any condition to hide yet:

 

DateTime dt1 = DateTime.Now;

string datetoday = dt1.ToString();

lblDateToday.Text = datetoday;

DateTime AddDay = DateTime.Now.AddDays(3);

lblDateAdd2.Text = AddDay.ToString(); 

 

 Please help anyone...
