Is there a way using DateTime.Parse to validate a date in the following format?

mm/dd/yyyy

Thanks

Sure - give the format to DateTime.Parse or DateTime.ParseE xact. Note
that in custom format strings, "m" is for minute - "M" is for month.

If it is valid it will not throw an exception, otherwise it will. Example:

try

{

DateTime a = DateTime.Parse( "01/10/200a");

MessageBox.Show ("Date is good!");

}

catch (Exception ex)

{

MessageBox.Show ("Date is not in proper format.");

}

This will throw an exception and display a message box. Other way is to
use a regular expression.

MessageBox.Show ("Date is not in proper format.");

just a note: a specific Exception should be caught always when possible
As commonly said "Imagine an OutOfMemoryExce ption would be thrown"...

I have put my users through so much crap with this bug it is an absolute shame. I have a product that reads/writes RSS 2.0 documents, among other things. The RSS 2.0 spec mandates an en-US style of date formatting (RFC 822). I have been using a variation of RFC 1123 (just change the time zone to an offset, i.e. "-0800"). It seems to be writing okay, but it's failing to parse. I've tried changing the regional & language settings in my...

I've got a section of code in my app that keeps track of how much time an employee has accrued, which equals out to 1.33 days of PTO per month. I'm trying to store the time accrued so far in an XML file. I have no problems writing to and reading from the XML file and all my values are correct. The problem I'm having is my calculation never amounts to 1.33, it goes from 1.32999999999997 to 1.3743333333333. on the next run.

Consider an application which has *many* references to DateTime.Parse(string); Is there a way, say when the application first starts up to force this method to use a specific IFormatProvider, so every DateTime.Parse(string) is really DateTime.Parse(string, format);

I'm sure there's a good explanation for this, but I can't figure it out. I tried using DateTime.Parse() with a custom DateTimeFormatInfo instance, in which I'd replaced the DateTimeFormatInfo.FullDateTimePattern property with my custom format string: DateTimeFormatInfo dtfi = (DateTimeFormatInfo)DateTimeFormatInfo.InvariantCulture.Clone(); dtfi.FullDateTimePattern = "dd/MMM/yyyy:HH:mm:ss zzz";
