DataContract XML Serialization And XML Attributes With .NET?
Oct 21, 2011
DataContract XML serialization and XML attributes which is most interesting I have attempted to directly convert it to VB.NET, but it does not seem to give me the right results. All I get is the root element with no attributes:
<ServiceContract()>
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>
<ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>
Public Class Service1
We need to specify a certain sort order for the fields of a class which is serialized to XML. sort order when dealing with XML elements but in our case there's a reason to do so.
So ... this answer for C# advises using XmlElementAttribute and I've translated the C# to VB as:
<System.Xml.Serialization.XmlElementAttribute(Order = 1)> _ Public Property Foo() As String etcs
But it complains that Name 'Order 'is not declared. Have I mistranslated from C# or is there some other issue here?
I've added a service reference to my WCF webservice which generated all of my datacontract objects. I'm using BasicHttpBinding. Using a partial class, I've made one of these objects inherit from another class that adds some properties to it.[code]...
But when I come to do a test project to test my service, no namespace does not appear, and put my two classes are the same. The Intellisence going to my first class with the name Reply, and the second class with the name Reply1, while I wanted the same hierarchy with my classes. So I wonder if it is possible to do? I look forward to your responses.
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:
You read the title and groaned. That's okay. I did too. But we do what we're asked, right? I need to build a service that can be accessed via a moniker from within Excel (2003, but I'm assuming any version of Excel should support this functionality). At the moment all I want to do is have a spreadsheet post data to a WCF service running from a Windows service on a remote machine. Because that data needs to be retrieved by something a little more sophisticated than VBA, I decided to set up a data contract. Here's my code (at the moment this is just a proof-of-concept, but it's closely related to how it needs to look when it's finished).
[Code]...
If I include the DataContract attribute and the function that returns the data contract object, my vba code fails in the Public Sub PutData method with the following:
"Instance of MessagePartDescription Name='GetWhatsResult' Namespace='http://tempuri.org/' cannot be used in this context: required 'Type' property was not set."If I take out the DataContract and comment out the function in the service definition, I'm fine. I don't plan on using the GetWhats() function from within Excel. But yet I'm guessing it wants the type definition for TheWhats.From what I've read one solution seems to be making this a COM object and referencing the DLL. However that isn't a workable solution for my environment. Is there another way to fix this?
I 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
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:
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.
I have a MRU list that keeps on clearing when I close my application. In order to keep this information, I am trying to serialize it to an xml file, however, I can't figure out how to get the list written to this xml file.
Class <Xml.Serialization.XmlRoot(ElementName:="Class_mrulist")> _ Public Class MRULIST
I 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.
I 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.
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.
what the relation between Serialization and encrypting files, i wanna know that and i wanna a lessons for serialization and i want to ask about this code in VB6 if we can convert it to VB.net 2008
Dim a As String * 10 Dim b As String * 10 Dim c As String * 10
I am new at this. Im trying to serialize a panel and its contents in vb. The controls are added at runtime. I have tried adding to a arraylist but it didnt work
I'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 tryed using serialization I might be using the wrong thing though what im trying to do is to serialize a class to a .bin file and then use it from another application, is there a way to change the specification of the binary formater this way it works in two different Vb.NET projectS??
I am making a FlowLayoutControl panel which the user can edit by dragging controls onto it in any required order. The controls are mainly (subclassed) Buttons and (subclassed) TextBoxes, plus perhaps a few labels. There might easily be several hundred of them interspersed at random. I need to be able to save the FlowLayoutPanel and/or its list of controls to a file, and then restore the whole thing again later when needed.If I am not mistaken, this will involve serialization -- a subject about which I presently know next to nothing. I have tried trawling the web for introductions and relevant examples, but I am suffering from information overload. There is so much written about serialization that I don't know where to start.As I can't spend too much time on this, I'm hoping there is some simple way through all the complications. Can anyone here explain, or point me to, the basics needed for saving a control like my one?
I've written one pgm that used byte serialization to save a file. It eventually morphed into a program and a library class (dll) so I could save/retrieve the byte serialization/desrerialization file from a different program that would use the same dll that originally serialized file in the first program. But, the first program seems to own the serialized file, not the DLL. The first progam is GenerateEventList and has the added reference Imports EventDBS which is the DLL. The second program EventDisplay also has Imports EventDBS to read the file. It produces the exception:
I'm want to serialize a list(of Animal) of objects with different subclasses of type "their own type" but getting nowhere as exceptions doesn't give out any useful information. I've set up the serializer method which which serializes individual sublass objects if I declare them with their own type but not if I declared them as a derived (Animal).
Code is below: Public Sub XMLPersistAnimalList(ByVal filePath As String) Dim serializer As New XMLSerialization(m_animalList, filePath) serializer.Serialize(Of List(Of Animal))(filePath, m_animalList) '------doesn't work! [Code] ......
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.
I am working with VB.NET and I am facing a problem with XML serialization. When empty values exists in the object I am serializing, the XML file contains the following tags:
<tagName/> instead of: <tagName></tagName>
I know that it's the same, but I want the start tag to close appropriately.
I have an error in the the following class, but am unsure where it is. The class will return correctly in my service but does not serialize and return any results.
This will not be the final iteration of GetEmail, but I am using this in it's current state to try and figure out why I am not getting the class to serialize correctly.
