Comparing date and time

[Guest]

Hi, i have two datetime values in format 11/22/04 9:00 AM and 11/22/04 9:30
AM. How can i compare dates .net c# or if there is any other way such as
Javascript.

Thanks

Hi Manny,

You either have 2 DateTime values, or you have 2 strings in the format
11/22/04 9:00 AM and 11/22/04 9:30 AM. DateTime values don't have formats.
They are pure data. The System.DateTime class has many methods for comparing
DateTime values. In addition, some camparison operators can compare DateTime
values. For example:

Dim ahora As DateTime = DateTime.Now
Dim SomeDate As DateTime = SomeFunctionThatReturnsADate()
If SomeDate > ahora Then...

Note that I spoke of comparing DateTime values. DateTime is a Data Type.
Comparing 2 strings will only tell you which string is alphabetically before
the other.

Manny,

If you are attempting to only compare 11/22/04 with 11/22/04 and ignore
the times, you can compare string objects of these DateTime objects
with using .ToString("d")

So a DateTime object of value {11/22/04 9:00 AM} with .ToString("d")
equates to "11/22/04"
Hope this helps!
