You're in the
dotnet xml
group:XmlSerializer fails to serialize xsd.exe generated classes
dotnet xml:
because they are too large (93KB and 1.2KB) I downloaded the ESRI ArcXml schema and generated the classes from the schema using xsd.exe, which took a while because xsd doesn't handle recursive elements very well (StackOverFlow exception during generation). Now that I have the classes I am trying to serialize them to an xml document to send to ArcIMS to generate map images. The .trc file is a text file that contains the exception information that this throws. This is the only document I am able to find on this bug on the web, convieniently on MSDN: http://msdn.microsoft.com/netframework/programming/breakingchanges/designtime/xmlserial.aspx The only solution that I can come up with is to install VS2003 and compile the ArcXml classes since this seems to be something that has been broken in VS2005 Thank you for your time, Russell
This is the test code that I am having trouble with, it fails on the first
line of the try block: using System; using System.Collections.Generic; using System.Text; using System.Xml; using System.Xml.Serialization; using ESRI.ArcIMS.Server; using ESRI.ArcXml; using System.Diagnostics; namespace ArcXmlTest { class Program { private static ARCXML CreateImageRequest() { ARCXML ax = new ARCXML(); REQUEST req = new REQUEST(); GET_IMAGE gi = new GET_IMAGE(); ax.Item = req; req.Item = gi; return ax; } private static XmlDocument Serialize<T>(T xmlObject) { XmlSerializer xs = new System.Xml.Serialization.XmlSerializer(typeof(T)); StringBuilder sb = new StringBuilder(); using (XmlWriter xw = XmlWriter.Create(sb)){ XmlDocument xml = new XmlDocument(); xs.Serialize(xw, xmlObject); xml.LoadXml(sb.ToString()); return xml; } } static void Main(string[] args) { ARCXML arcxml = CreateImageRequest(); GET_IMAGE imageRequest = ((GET_IMAGE)((REQUEST)arcxml.Item).Item); PROPERTIES props = new PROPERTIES(); imageRequest.Items = new object[] {props}; imageRequest.ItemsElementName = new ItemsChoiceType4[] { ItemsChoiceType4.PROPERTIES }; props.Items = new object[]{new ENVELOPE()}; TextWriterTraceListener listener = new TextWriterTraceListener(@"c:\ArcXmlTest.trc"); Trace.AutoFlush = true; Trace.Listeners.Add(listener); try { Trace.WriteLine(Serialize<GET_IMAGE>(imageRequest).OuterXml); Trace.WriteLine(IMSConnection.Send(arcxml.Serialize().OuterXml)); } catch(System.Exception e){ Trace.WriteLine(e.ToString()); } } } } [quoted text, click to view] "cd~" <ralibey@community.nospam> wrote in message news:uEkY1M1IGHA.916@TK2MSFTNGP10.phx.gbl... >I can provide a test app, the news server won't allow me to post the files > because they are too large (93KB and 1.2KB) > > I downloaded the ESRI ArcXml schema and generated the classes from the > schema using xsd.exe, which took a while because xsd doesn't handle > recursive elements very well (StackOverFlow exception during generation). > Now that I have the classes I am trying to serialize them to an xml > document > to send to ArcIMS to generate map images.

Hi,
Could you send the repro project directly to me by email since I don't have ArcXml on my machine? Remove 'online' from the nospam alias is my real email. Kevin Yu ======= "This posting is provided "AS IS" with no warranties, and confers no rights."
I sent the projects and documentation to you yesterday, did you recieve it?
thank you!! -R [quoted text, click to view] "Kevin Yu [MSFT]" <v-kevy@online.microsoft.com> wrote in message news:l4Ndd1iJGHA.3944@TK2MSFTNGXA02.phx.gbl... > Hi, > > Could you send the repro project directly to me by email since I don't > have > ArcXml on my machine?

Hi Russell,
Thank you for sending me the code. Yes, I have received it yesterday. And it took me almost half day to debug on it. But I'm sorry, since the xsd and the generated class was too big, I still cannot find how the problem was caused. Looking at this issue, it might need intensive troubleshooting and I suggest you try to contact Microsoft PSS on it. You can find their contact information from the following link: http://support.microsoft.com/default.aspx?scid=fh;EN-US;OfferProPhone Kevin Yu ======= "This posting is provided "AS IS" with no warranties, and confers no rights."
The problem is that xsd uses an object array to store the items themselves
and an array of values from an enumeration (ItemsElementName, i believe) to determine what type of element is stored in each array indice. It appears that the serializer expects an object array to hold the element type indicators and it is stored internally as an array of <enum type>, which it can't seem to cast to an object array, thus causing the mismatch. I appreciate the time you have spent on this.

Sorry that I wasn't helpful. And it's glad to know that you have found the
cause of problem. Kevin Yu ======= "This posting is provided "AS IS" with no warranties, and confers no rights."
