https://bugzilla.novell.com/show_bug.cgi?id=682957#c0 Summary: XmlElement deserialization failed with DataContractSerializer. Classification: Mono Product: Mono: Class Libraries Version: 2.10.x Platform: x86 OS/Version: Ubuntu Status: NEW Severity: Normal Priority: P5 - None Component: WCF AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- Created an attachment (id=421616) --> (http://bugzilla.novell.com/attachment.cgi?id=421616) A source that repro an error and stack trace User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0) Unable to deserialize instance of data contract that contains XmlElement data member. The following data contract can be serialized with DataContractSerializer, but not deserialized: [DataContract] public class XmlSerializable { [DataMember(Name = "Content")] private XmlElement m_content; public XmlElement Content { get { return m_content; } set { m_content = value; } } } Reproducible: Always Steps to Reproduce: Populates XmlSerializable::Content property with XML data, serializes instance of XmlSerializable class and deserializes it again. Actual Results: Unhandled Exception: System.InvalidOperationException: Failed to set value of type System.String for property System.String InnerText ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object Expected Results: Successfully deserialized member with XmlElement type. I think that DataContractSerializer implementation(on Mono) requires non-null value of data member with XmlElement type when deserializing. MSDN documentation describes this situation in strong form, with On deserialization, an XmlElement is created by the deserializer from the incoming XML. This case is unambiguously treated by MSDN documentation: "On deserialization, an XmlElement is created by the deserializer from the incoming XML. A valid parent XmlDocument is provided by the deserializer." http://msdn.microsoft.com/library/aa347876.aspx -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
