Hi,

My nullable Interval Day To Second type has been properly translated into a TimeSpan? .Net type. I'm passing an entity containing a duration field from the client machine to the server through WCF (MSMQ binding). At client side the duration field value is valid but after serialization in MSMQ and reception of the IEntity2 parameter in the service implementation the value gets corrupted. If I debug the value it says Duration threw an exception of type 'System.InvalidCastException and the insert in oracle throws ORA-1867: the interval is invalid.

Please help.

What's the value after deserialization? You can determine that via the CurrentValue property of the field object. What's the type as well?

THe CurrentValue (entity.Fields["Duration"].CurrentValue) is the following "00:00:03.5313404". Which seems OK. If I call entity.Fields["Duration"].CurrentValue.GetType() I get {Name = "String" FullName = "System.String"}. I would have expect TimeSpan.

Thanks.

Every type is serialized to strings, as XML is just text. Deserialization then should take these strings and convert them back into objects. Timespan isn't a predefined type so the serializer works with text.

This of course doesn't work, so we'll add Timespan to the types which require special care. Expect a new build for v2.5 (and v2.6) early next week (monday) which fixes this.

Many thanks.

Could you try the attached dll to see if it fixes your problem? You've to test it at the side where deserialization takes place, as the error is in hte deserialization code.

It works now.
