I'm trying to serialize a user's preferences by means of an XMLSerializer. The preferences class contains Strings, Integers, Booleans and several Color structure variables. The serialization doesn't throw any errors, however the generated xml file has empty values only for the color variables.I tried the following two declarations of the XMLSerializer object, neither workerd.
[Code]...
Is there any way to create an XmlSerializer that stores along with the serialized data the data type, then when deserializing, it automatically identifies the type of the serialized object and creates an object of that type (returned as object).
View 1 RepliesI've been having problems with following code on some computers, while it's worked super on others (most):
Dim xmlSer As New System.Xml.Serialization.XmlSerializer(GetType(XMLContext))
which produces the stacktrace:
System.ArgumentNullException: Value cannot be null.
Parameter name: type
at System.Xml.Serialization.XmlSerializer..ctor(Type type, String defaultNamespace)
How can that code throw that exception, when the argument is drawn from a gettype call, and note that it doesn't happen when debugging on my own PC, only when it's installed on some of the client PC's???
I wish to put the XMLSerializer behind a 'facade' class of mine so that user wont have to supply type info to the constructor. But doing this has a problem. Consider this class:
Class XmlFormatter
Private Shared xs As XmlSerializer
Public Function Deserialize(ByVal serializationStream As Stream) As Object
Dim o As Object = Nothing
[code]....
The problem is that the user of this class cannot use Deserialize without first using Serialize because the XMLSerializer instance is created in Serialize and it is shared. But using Deserialize without this instance will simply return Nothing.
I've been using XML serialization for a while, and today I realized something really odd. If I have a new line right after a "dot" (.), when i deserialize, I lose the dot. Has anyone ever had this happen to them? The following is my serialization code:

I have not yet tested this..but before I do that, I am just wondering, let's say you have a byte stream, and you want to deserialize that into an object?[code]...

0I Have a vb6 application that uses .net objects via COM. When one of this objects calls code which instantiates XmlSerializer vb6 aplication crashes.Just this line fails: Dim x as new XmlSerializer(GetType(CustomClass))I agregate that these objects load assemblies dinamically but only it crashes over vb6 aplication. In .net 100% aplication this not happens.
View 2 RepliesI have two experimental web services. One is an asmx contained within a .net web application. The other is a WCF service library being invoked from the web application.The asmx basically does everything I need, but I think WCF would be better, except that it doesn't do anything as I would expect after fiddling with the asmx service.For example, the same method behaves differently in each:
' ASMX
<WebMethod(BufferResponse:=True, EnableSession:=False)>
Function Test(aObject as Object) as Object
' object will have been successfully serializaed into a dictionary

I have a custom class that has one property as a collection.For some reason XmlSerializer doesnt like the class having a collection property and the Serialize Fails!If I remove the collection property it works! Is there a special way of getting the collection in the class to work?
View 1 RepliesI am trying to deserialize an Xml file content into a specific object. Everything runs fine but when I include empty tag of type date or time in my xml(having xsd that describes my xml structure) the deserialization fails. What can I do to make deserialization working when empty date tags are appear?

Why is XMLSession.FileList.Count always 0. I hypothesize it has something to do with the declaration above it but I am not sure what is wrong with it. Maybe it can't accept a path, if not, how can I do it?
I've been serialising and deserialising .net objects using the XmlSerializer class without problem, however we now need somebody else to look at that data to perform some analysis on it.In order to help with that we've produced an XSD based on our class like so:
xsd.exe /t:DataClass Assembly.exe
The start of the XSD looks like this:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="DataClass" nillable="true" type="DataClass" />[code].....
Bizarly, the XML produced does not adhere to the XSD generated from the same class.My question then is, is there a way of telling the XmlSerializer to serialize the object based on a given XSD? As an aside, I've looked at other ways of fixing this: I've tried re-generating the classes from the generated XSD - this seemed to have the same problem.

View 3 RepliesI have a base class ("MyBaseClass") in a project called "BaseFramework" which is included in several solutions within the company. There are several derived class's in various projects throughout the company that inherit from "MyBaseClass". If I then create a List and add derived class's to it, it will not serialize. I realise that if I were attempting to serialize this list, and the base class and derived class were in the same project, I could simply apply the "XmlInclude" attribute to the base class and include all of the derived class's. This is however not possible across projects, because that would require a circular dependency.
View 1 RepliesI am attempting to solve the well known problem of automatically generated serialization assemblies in VS 2010, both VB.NET and C#. The "Generate Serialization Assemblies" option in project settings does nothing for non-web projects (see [URL]). Thus the calls to serializers generate file i/o exceptions that are very unfortunate, and for which there is no cure. The method suggested above does not appear to work with VS2010 and SGEN still runs with /proxytypes enabled.

OK Here's the code:

<ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>
Public Class Service1

The output is:

Which as you can see does not have success and timestamp as attributes.
I am creating a new windows program and I have used XML serialization to save the contents of my text boxes but when I try to open that file in the new application, no data is transferred. The code acts like it does everything fine and does not give me any errors, it just doesn't input the text back into the program.
Here is my code:
Imports System.Xml.Serialization
Imports System.IO
Imports System.Runtime.Serialization.Formatters.Soap

View 2 RepliesI've been cloning my objects using serialization for awhile, and typically its been quick, at least for my purposes. After a series of updates to these objects, however, now the serialization process is much slower. Trial-and-error has so far failed to pinpoint the cause. Some of the added elements to my object are:
1.binding lists
2. an inherited dictionary class
3. more internal references (the object is actually group of nested objects, and these internal objects have more references to each other than before)
I have been careful to avoid/eliminate references to external elements when cloning, as that can lead to a cascade of extra cloning. So I think the problem is with the object structure itself. This is my serialization routine:
Friend Function CloneObj(ByVal obj As Object) As Object
If Not obj.GetType.IsSerializable Then Throw New Exception("Object not serializable")
Dim bf As New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter

I'm creating an application that uses several "multi-leveled" structures (structures within structures within structures....) to store reference data.

Three questions:
1) Is the "CloneObject" function solution able to be used in my application?
2) If it is, what is the fix for the XCData typed objects?
