The question looks incomplete, as its not clear.

But if you are trying to compare the date filed you can look into DateTime.Compare(d1,d2) method. Which expects 2 date variables to compare and returns an integer value of number of date differences, so return value is less than 0 then d1 is smaller than d2, if equals to 0 then both are same dates and if returned value id greater than 0 then d1 is greater date than d2.

Hope that this helps you.
