C# - Serialize List Of Objects In Android And Deserialize In WCF?
Apr 17, 2012
I have an ArrayList in android that I'm trying to convert to a Base64 String, then passing that to a wcf service though JSON and the wcf service inserts the string into a database. Then I need to be able to read that from the database and deserialize it in a .NET application.
This is how I am serializing the ArrayList in android:
private String convertByteArrayToSave(byte[] b){
if(b != null){
return Base64.encodeToString(b,0,b.length,Base64.DEFAULT);
}else{
[Code]...
The ultimate goal is to be able to be able to create a list of these shapes in the .NET app or android app and be able to read the list in the .NET app and android app no matter where it was created from. I'm able to it when you create the Shape from .NET and read it into android using WCF but creating it in android.

I have an XML document that I am deserializing (VB .NET 3.5 Framework), changing some values, and the serializing again. The original document has several XML Comments in it. When I go through all the deserialize/serialize all of the comments are lost. Is there a way to preserve the comments? If not, is there a way to add comments on serialization without having to walk through with the writer and manually add all of the comments back in the appropriate place?

How do I serialize and deserialize my main form (and its controls, subcontrols, their values, etc.)? Edit, for clarification. Currently I am writing the current value of each control to an .INI file, one by one and reading it back when the program is next run. Every time I add a new control, I have to remember to update that save/load .INI code.I just wondered if I can do it in one call, or a simple for loop iterating over all controls on the form.Btw, I use only simple controls like edit box, radio button, combo box, checkd listbox, the most complex thing I have is a datagrid, but even that is not linked to a databse.Accepted answer "can't. I will probably code my own, along the lines of ...
[code]...
maybe later add left/top/height/width/enabled/visible, etc, bu tfor not th econtrol name an its "value" are enough (text, value, lines, checked?, etc)

Is it possible to serialize and deserialize a structure?
I think it isn't because the code I use will not work for a structure but it does work for other data types like an array, string etc

I am trying to write a class to serialize/deserialize something as simple as:
<table border="1">
<tr>
<td>row 1, cell 1</td>
[Code]....
I just can't get it to serialize to this thing. I tried to generate the class using xsd but that produced a lot of garbage code and I really would like to maintain this by hand as it is easier than the monstrosity that xsd produced which didn't work anyway.

I have a question about serializing a Picturebox and it's child controls. I have a picturebox on my main form where a user can put new Picture boxes in.To a add a new Picturebox I say: Pictureboxmain.controls.add(Picturebox)But now I want to serialize this in a stream of bytes. I know that you can serialize an Arraylist as followed:[code]But is the same possible with a collection of controls?So now I tried this assuming the same method can be used with a control collection:[code]

The general idea of whats going on is i am trying to transfer a structure from one project to another using binary and sending through a TCP Stream.

I've tried posting this to a few forums, even microsoft... Hopefully this forum is the place to be.
I'm programming an application in Visual Studio 2010, namely in VB.net. I have been developing an application which uses a derived class inherited from TreeView, with the aim of putting custom objects on the nodes. The method I have been using is to have a variable array against the node (of type object) which contains variables in custom classes to contain each of the variables associated with the node.
The two problems I had to overcome were, how to serialize a TreeView, and how to serialize an array of objects (of variable type). Good thing is I overcame both of these with some work of some other folks (and 3 days of my own work).[code]....

I am attempting to deserialize a simple JSON array to .NET objects using the JSON.NET library in visual basic.
For the life of me, I cannot figure out what I am doing wrong here. My JSON string deserializes into appropriate objects (9 in total), but none of the properties are populated.
My code:
Public Class result
Public Property id As Integer
Public Property vote_percentage As String
[Code]....
When using JSON.NET you have to have constructor methods (i.e. Sub New) in order for the properties to get set during the Deserialization call.

Using the following code:
Private Sub MakeMeSomeXmlBeforeRyanGetsAngry()
Dim db As New MyDBDataContext
Dim customer = From c In db.Customers Select c
[code]....
I am attempting to serialize my linq collection of customers. But it keeps throwing
Type 'System.Data.Linq.DataQuery`1[MyDB.Customer]' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. See the Microsoft .NET Framework documentation for other supported types. My issue is that I have already marked the dbml Serialization Mode to UniDirectional and when I check the dbml codebehind all of the DataContract()> and DataMember()> elements are there. I have tried adding various dataloadoptions and setting deferredloading to false, but no luck.

I have one class with <Serialize> attribute called Tree. And Tree class has an arraylist of TreeNode classes. Is it possible to use Soap to convert the Tree class and arraylist of TreeNode classes to one xml file or binary file? If it is possible, do i need to use <Serialize> attribute on TreeNode classes too? If not, what should i do then?

I have a class called Tree, it has an arraylist called alTreeNodes. alTreeNodes is an arraylist of TreeNode class. Since I am using ISerializable Interface, I have to provide a specific constructor. I know how to write it for string parameters such as name_value, but how should i do with arraylist of object then? See "???" in the code blog before.

How best to manage multiple dat files for serializable objects of the same class. If one of my data files goes past a particular size, I want to create a new file. I then loop through both files when I do processing. Is there any easier way to do this and what's the best size to do this at in terms of performance?

It is my first time trying to serialize an array into xml list. Couldn't really find a nice tutorial out there on xml.
I have
dim Array() as integer = {1,2,3}
dim Value() as string= {Value1,Value2,Value3}
When the array is serialize, i guess, i want to try to get the format to look like below:
<p data="Value1">1</p>
<p data="Value2">2</p>
<p data="Value3">3</p>
How o it serialize into this format, and de-serialize back into an array?

I am trying to serialize a class that contains a generic list, and I am finding it all works with the exception of the generic list property. That is to say the other properties are serialized fine and no error is produced.
I have in the past serialized an arraylist - but I thought it was possible to do a generic list in the same way.
Am I missing something or is it not possible to serialize/deserialize a generic list - I have read mixed comments on this..
The relevant parts of the class that gets serialized is defined as..
<XmlInclude(GetType(cConfigUser)), _
Serializable(), XmlRoot(ElementName:="Config")> _
Public Class cConfig

I'm having a bit of a 'brain doner' moment here
I have a list of Objects. Each of these Objects contains a list of other Objects (pseudo code) :-
Private Structure Object1
dim Name as string
dim ListOfObject2 as List(Of Object2)

I need to sort the list of Object1 by the Value in Object2. I have a comparison class which sorts Object2 by its Value nicely.

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?

Limited to using v2.0 of .Net framework (we use VB.net) due to environmental constraints on our servers.I've got an ASP.net webpage which pulls data from a webservice that performs checks on user accounts in active directory. Operators can check multiple accounts at one time using the web interface. The webservice returns a list(of AccountCheck) objects which themselves contain single properties like username, email address, and List(of AccountError) objects which contain multiple properties.[code]What I want to do is using some kind of repeater, create multiple panels or divs which contain labels showing the username, email etc, and a gridview which has the accounterror list bound to it to show all the errors. The users could be checking 2, 5, 7 accounts at once, and is dynamic.
