Check difference in seconds between two times

Question

Hi all I am currently working on a project where when a certain event happens details about the event including the time that the event occurred is added into a list array    Once the method has finished I then pass on the list to another method that checks its values  Before I go through the loop I check the current time of my PC and I need to check whether the difference between the time saved in the list array and the current time is greater than 5 seconds    How would I go about doing this

Assuming dateTime1 and dateTime2 are DateTime values   var diffInSeconds    dateTime1 - dateTime2  TotalSeconds    In your case  you  d use DateTime Now as one of the values and the time in the list as the other  Be careful of the order  as the result can be negative if dateTime1 is earlier than dateTime2
