DateTime.Parse .. what's different in .NET 1.1

Hello

In .NET 1.0, the following code worked fine


public string dateFormat = "yyy-MM-dd\"T\"HH:mm:ss.fff zzz";
DateTime date, minDate;

date = DateTime.Parse(minDate.ToString(dateFormat));

In .NET 1.1 I get an System.Format exception
For Example, this generates a System.Format exception

DateTime.Parse("2003-08-23T20:50:05.365 +05:30");

Is something changed in .NET 1.1 ?

Thanks

Ah .. apologies my mistake. But in any case that was not the source
of the problem.

In .NET 1.1, this throws a SystemFormat exception
DateTime.Parse("2003-08-23T20:50:05.365 +05:30");
but it worked fine in .NET 1.0.

It is the extra space before the timezone which is the cause of
the problem. It is not standard ISO8601 format.
Thus the following format string should have been used

"yyyy-MM-dd\"T\"HH:mm:ss.fffzzz";

Could you please let us know why there is a T in the string?

Presumably because it was meant to be ISO8601 compliant, which means
including a T. From the MSDN sample of output patterns, using standard
formatter s which (according to the docs) conforms to 8601:

2001-04-10T15:51:24

Also from the MSDN:

<quote>
The property references the CultureInfo.InvariantCulture property, and
the format follows the custom pattern "yyyy-MM-ddTHH:mm:ss".
</quote>

The T should definitely be there as far as I can see.
 
Hello Atul and Jon,

After working with product group, we have confirmed that it is a product
issue here. It has been fixed in the next version of VS.NET.

Here are some work around options:

1. Configure the source of the data to not format the dates with a space.
2. Use PaseExact('yyyy-MM-dd'T'HH:mm:ss.fff zzz') instead.
3. Clean up the data using String.Replace or a Regex replace.

Please post here to let us know if you have follow up questions. Thanks
very much for your feedback on the product. We appreciate it very much.

Best regards,
