Recurrence Exception

[Ashish Sapkale]

Hello,

I am adding exception to Recurrence rule.

I followed this link Recurrence Rule Excpetion

1.RecurrenceRule RecurrenceRuleEvent = RecurrenceRule.TryParse(strRecurrenceRule);
2.RecurrenceRuleEvent.Exceptions.Add((Convert.ToDateTime("8/25/2009 10:00 AM").ToUniversalTime()));

I want to add Exception to "8/25/2009 10:00 AM"

But this line adding exception to "8/25/2009 04:30 AM"

I have attached Screen shot that Whats the basic problem.

The Recurrence Rule after Adding Exception.

DTSTART:20100825T090000Z
DTEND:20100825T093000Z
RRULE:FREQ=HOURLY;INTERVAL=1
EXDATE:20100825T090000Z,20100825T043000Z,20090825T043000Z

Hello Ashish Sapkale,

Here is a quote from the reference of DateTime.ToUniversalTime() method:
"The UTC time is equal to the local time minus the UTC offset.".
That's why it's changing the value.

What you need is the SpecifyKind method of the DateTime type (here is a reference for it: http://msdn.microsoft.com/en-us/library/system.datetime.specifykind.aspx).
In order to remain the same value you can explicitly declare it as follows:

DateTime localTime = DateTime.SpecifyKind(Convert.ToDateTime("8/25/2009 10:00 AM"), DateTimeKind.Local);

Please, try that out and let me know about the results.

Hope this solves your problem!

1.DateTime localTime = DateTime.SpecifyKind(Convert.ToDateTime("8/25/2009 10:00 AM"), DateTimeKind.Utc);

Thanks 

This method works for me after I changed DateTimeKind to DateTimeKind.Utc.

Will this be problem If I am on different time zone ?

Hello Ashish,

It should work regardless of the current time zone.

I hope this helps.
