Looks like not a question. Maybe, incomplete question...

Compare the dates (or, more generally, points of time in the form of System.DateTime using the operators: "==", ">", "<", ">=" and ">=". Also, use "-" (subtraction) to find the time interval, duration.
 
System.DateTime before = //...
System.DateTime after = //...

//...

if (before == after) { /* same time */ }
if (after >= before) { /* as expected */ }
 
//...

if (after < before) { /* something's wrong */ }
 
System.TimeSpan duration = after - before; // as simple as that! now see how much time elapsed

Solution 1

Don't do ToString. why on earth would you ? A string comparison will not correctly compare dates. DateTime.Now is NOW. An hour from how is greater, an hour less is less. Remember that. Apart from that, if you remove the ToString, I bet you're getting a DateTime and this would work.
