Don;t use Parse: use TryParse or TryParseExact. Parse throws an exception is the user makes a mistake - which they do, all too frequently - the TryParse versions don't.

C#

DateTime dt;
if (!DateTime.TryParse(inputString, out dt))
   {
   // Report problem to user
   ... 
   return;
   }
if (dt > DateTime.Now.Date)
   {
   // In the future
   ...
   return;
   }

C#

string date = "2017-08-02";
DateTime myDate = DateTime.Parse(date);
Console.WriteLine("my date is: " + myDate);
		
if (myDate > DateTime.Now)
{
	Console.WriteLine("my date > " + DateTime.Now);
}
else
{
	Console.WriteLine("my date <= " + DateTime.Now);
}
