Deserialize A Simple JSON Array To .NET Objects?

Feb 3, 2012

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.

Try Catch In .net - Deserialize An XML Object

Feb 3, 2012

I was searching the most effective and elegant way do to the follows:

My function can be called while Filename is valid, corrupted, not exist

The function will just deserialize an XML object.

The main possible results are:

OK
File doesn't exist
Error in XML file

If I write this way, the reader won't be closed in case of corrupted file. IF I write the reader.close() inside finally block, It gaves me a warning about using read before assigning it a value.

So, how can I solve this inside the sub?

Public Function DeSerializzaXML(ByVal FileName As String, ByRef tmpObj As Object, ByVal tmpClass As Type) As Boolean
Dim serializer As XmlSerializer
Dim reader As StreamReader

Deserialize An Object When The Underlying Class Has Been Changed Slightly?

May 10, 2011

I've written a custom class MyClass and marked it with the <Serializable()> attribute. I have a set of binary files on my hard drive that I've serialized using BinaryFormatter that came from instances of MyClass.

I've recently changed the structure of MyClass slightly (added some properties, deleted some properties, changed a few methods, etc).

What happens when I try to deserialize the existing objects to this changed class using the code below? I've tried it and not had an error thrown or anything - but surely it can't deserialize properly when the class has changed? Is there a way I can get some useful information out of the serialized files even though I've updated the class?

Here's the code I'm using to do the serialization:

Public Sub serializeObject(ByVal obj As Object, ByVal outFilename As String)
Dim fStream As FileStream

I am looking for a vb.net library where I can insert data into an object and have it spit out a json formatted string, and also take the string in again to rebuild the object.I am not that concerned with mapping it to preexisting objects.I have searched around and every single library I've found either can't read the strings in again, interprets them as one long string instead of breaking them up into parts, or fails to work entirely (asp.net can't even find any public members).

Javascript - Accessing Elements Of JSON Object Without Knowing The Key Names

Feb 25, 2011

Here's my json:

{"d":{"key1":"value1",
"key2":"value2"}}

Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?

The reason my json is structured like this is that the webmethod that I'm calling via jquery is returning a dictionary. If it's impossible to work with the above, what do I need to change about the way I'm returning the data?

Here's an outline of my webmethod:

<WebMethod()> _
Public Function Foo(ByVal Input As String) As Dictionary(Of String, String)
Dim Results As New Dictionary(Of String, String)

Twitter Json - Unable To Convert To Jobject Or Jarray Using Json.net / Javascriptserializer?

May 9, 2012

I am been stuck on this for 3 days now...I have been accessing the twitter api to pull a user_timeline for a list of users and the json that comes back is impossible to work with. I tried to deserialize it using javascriptserializer and get an error:invalid object passed in , ':' or '}'

Now this is frustrating since I expect the json being returned to be error free. Then I tried json.net and split the posts using string.split and tried to convert each post to Jobject or jarray. for Jarray I get

'unexpected end of content while loading jArray

[Code]...

Now I have formatted the code here and not pasted the whole file but it does look like valid json to me and I do not alter anything after receiving the stream from the twitter api. Can someone please point me in the right direction? I really need to get this stuff parsed?
