Serializing XML With Strange Namespaces?

Question: How does the class for the serialization of this XML content look ?
<?xml version="1.0" encoding="utf-8"?>

I am having problems with serializing and de serializing my objects.The following is my code for serializing buttons and labels which I have in my form.
Dim nodes As New List(Of nodeclass)
Dim objStreamWriter As New StreamWriter(filelocation)
For Each btn As Button In myNodeBtns
Dim u As New nodeclass
[code].....
I get an error: There is an error in XML document (20, 3).Now I have found out that this is because I have 2 root elements and 2 xml declerations. When I save the xml for the button and te xml for the label in 2 different files, I have no problem. However I have no idea how to go about saving the xml for both of them in the same file and deserializing it back.

I have just finished my application and am stuck as to how I'm going to store my data. As it stands I have multiple objects that I created but each of them take multiple ArrayLists as properties. I'm aware that this will give problems if I try to serialize my data?

I'm trying out MVVM in VB.Net for a while now and started out with some of my entities using List(of T)s, which I xml serialized to disk. Now, I updated the classes used by the Lists to implement INotifyPropertyChanged so I also changed the List(of T)s to ObservableCollection(of T)s.After which, the XML serializer stopped working :'( A colleague told me that ObservableCollections, unlike generic Lists, are not serializable.If so then how can I make them Serializable?

I'm not positive I'm going about this the right way. I've got a suite of applications that have varying types of output (custom defined types).For example, I might have a type called Widget:
Class Widget
Public name as String
End Class
Throughout the course of operation, when a user experiences a certain condition, the application will take that output instance of widget that user received, serialize it, and log it to the database noting the name of the type.
Now, I have other applications that do something similar, but instead of dealing with Widget, it could be some totally random other type with different attributes, but again I serialize the instance, log it to the db, and note the name of the type. I have maybe a half dozen different types and don't anticipate too many additional ones in the future.
After all this is said and done, I have an admin interface that looks through these logs, and has the ability for the user to view the contents of this data thats been logged. The Admin app has a reference to all the types involved, and with some basic switch case logic hinged upon the name of the type, will cast it into their original types, and pass it on to some handlers that have basic display logic to spit the data back out in a readable format (one display handler for each type)NOW... all this is well and good...Until one day, my model changed. The Widget class now has deprecated the name attribute and added on a bunch of other attributes. I will of course get type mismatches in the admin side when I try to reconstitute this data.
I was wondering if there was some way, at runtime, i could perhaps reflect through my code and get a snapshot of the type definition at that precise moment, serialize it, and store it along with the data so that I could somehow use this to reconstitute it in the future?

Possible Duplicate: Fastest serializer and deserializer with lowest memory footprint in C#?
I'm using BinaryFormatter class to serialize an structure or a class. (after serialization, I'm going to encrypt the serialized file before saving. (And of course decrypt it before deserialization))But I heard that some other serialization classes are present in .Net Framework. Like XmlSerializer, JavaScriptSerializer, DataContractSerializer and protobuf-net.I want to know, which one is best for me?Less RAM space needed for serialize/deserialize is the most important thing for me. Also speed is important.

I'm just starting out learning C# this may be really simple but in VB i have these namespaces
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Globalization" %>
<%@ import Namespace="System.Data.SqlClient" %>
How do I go about using those namespaces in C#?
I tried
namespace System.Data
and
using System.Data
but they didn't work

I've been reading up on this whole subject, but I never came across this specific problem. I already understand that the whole idea of serializing an entire form is a horrible idea and just doesn't work. But, I am encountering a bit of a different problem. I have a class that inherits the "button" form object, that I call DataButton.
Now for my problem. I want to be able to serialize this class, but I don't need any of the information from the actual button class. Is there any way to bypass the fact that I can't set the button form object to Serializable() and notify VB that when serialization is to occur, it should simply skip over that information? Theoretically, if such a procedure were possible, I'd be able to do the entire serialization without a hitch.
I came up with the idea earlier of removing the "inherits" feature from the class, and having simply a button within the class, but that makes my program really difficult to work with as I am constantly changing the location, size, backgroundImage, text, and whatnot. Thus, immediate updates would be much tougher to work with.

Often it is very usefull to save data as a class by serialize and compress it. From few experiments I have noticed that
Class A
Public name as string
Public List as new list(of string) <---- empty
End Class
Class B
Public name as string
Public List as list(of string) <----- not instantiated
End Class
If I serialize and compress the 2 classes the class B uses less spaces once serialized and compressed. This suggests me that if a class contains a list that is instantiated but empty it is better to set that to nothing and reset as new when it is decompressed and deserialized. Is there any dll that optimizes a class to be stored (serialized and compressed) and restore it when it is decompressed and deserialized?

I am in the process of writing a base class for gadgets that will be displayed on a form.I want the gadget to be fully self contained and reusable.At this point it does everything that I need it to do EXCEPT, i'm having trouble figuring out a creative way to serialize my objects using only one object.I have a feeling the answer lies somewhere within the context of using shared functions but I'm having trouble wrapping my mind around it.

I apologise if this thread has been posted in the wrong section I was not certain whether it was the serialization or the networking that was causing this problem, but I feel that it is likely that it is the serialization.I am currently building two applications a client and a server, where several objects have to be sent between the applications, a couple objects each way.The applications are called "ACME Server" and "ACME Client" (yay for originality).
While I can get the first object to be transferred from the client to the server, but I can't get the second object to be transferred successfully from the server to the client, the error is occurring in the client program, I have taken a printscreen of the error that I am receiving, which I have uploaded to [URL]..All objects that are being sent are serializable (well there is an Interface called Action which I am unable to make serializable I believe due to it being an Interface).

In C#, if you do this, it will compile:
namespace Name
{
public class Test
{
[code]....
I get (depending on the way I try to use "Test") either "'Name' is not a member of '<Default>'." or "Type 'Name.Test' is not defined." in my error list. I've found two ways to make it work, but neither are reasonable to expect of a user. One is to remove the "Root Namespace" from the project properties. The other is to include that namespace between "Global" and "Name".
I have made a custom tool that uses CodeDom to generate code for both C# and VB.NET. This is the reason why neither of the two fixes above are feasible: I can't expect my users to have an empty root namespace, and I'd hate to have to do VB-specific tricks in my code generation (kind of defeats the purpose of using a language-neutral tool, doesn't it?) such as picking out the "Root Namespace" (not that I'd know how off the top of my head) and including it in my code generation.
I don't want to leave out the global modifier either, because it protects the tool from users picking bad names for the generated output. Does anybody have a suggestion for how I should deal with this?

Is something like this possible?
Namespace Transaction, Document
Class Signer
Public Sub New()
[Code].....
I basically want to be able to instantiate the Signer class from either Namespace. The reason is that I mistakenly set it up in the Transaction class and need to migrate it over to the Document class without breaking existing legacy code. I'd prefer to not have the same Signer class duplicated in both Namespaces if possible.

Surprised this question has not been asked yet here, but here goes: Serialization in VB.NET is a bit of a pain. If you use the standard Serializable() attribute, and attempt to serialize a class that has events which are attached to handlers, it will attempt to serialize the handlers as well. Coming from a C# background I am not used to dealing with this problem, and the best solution I can find is using a class off of CodeProject.

I am trying to create a load and save function for my customizable Menu/Tool/StatusStrip controls (see signature). Those three controls use a single AppearanceControl class, which is mainly just a large list of properties (Colors) which control the colors of the Menu/Tool/StatusStrip.
I want to be able to save and load the values of these properties so the user can store them and load others with ease. Serialization seemed the obvious answer, although I never used it before.
Now, there is a slight problem that I cannot serialize Colors, so I simply gave each Color property the XmlIgnore attribute, and created an Integer property that gets and sets the Color property (using Color.ToArgb and Color.FromArgb). This way I can serialize the color properties succesfully.
Then, there is another problem. The properties are not all in the AppearanceControl class. Instead, the AppearanceControl class has a large number of subclasses, which in turn contain the color properties.
As a small example, I may have this:
vb.net
Public Class AppearanceControl
Private _toolStripColorProperties As ToolStripColorProperties
Private _menuStripColorProperties As MenuStripColorProperties
[Code]....
