Could Not Deserialize JSON Object

like:
{"d":[{"_type":"Employee:#","BigThumbNailURI":null,"ID":1,"Name":"E1"},{"_type":"Employee:#","BigThumbNailURI":null,"ID":2,"Name":"E1"}]}
From VB.net code behind when I am trying to deserialize it it's stating that
"Expecting state 'Element'.. Encountered 'Text' with name '', namespace ''."
Deserialization code snippet:

serializer.WriteObject(memoryStream, s)
memoryStream.Position = 0.......

WCF / ASMX :: Can Get Different Json Datasets From The Same Object
Apr 6, 2010I want to serialize an object to json, so I'm using [Code]....
[Code]....
This is fine, but I want to return different json datasets depending on the circumstances. Lets say I have this object (a simplified example):
[DataContract]
class foo
{
[DataMember] int productId
[DataMember] string productName
double price; //not used in json.. yet
}
Which will serialize to a json object containing the product name & Id, but what if I also need to be able to return a different json object (say, productId and price but not name)? Can this be done somehow in the same object using WCF/DataContracts and DataMembers? This will be sent in an ajax query containing a collection of objects and needs to fast, so just including every member in every type of json request whether it's needed or not isn't a good solution.
Serializing Only Parts Of An Object With Json?
Feb 14, 2011I have an object called MyObject that has several properties. MyList is a list of MyObject that I populate with a linq query and then I serialize MyList into json. I end up with something like this
List<MyObject> MyList = new List<MyObject>();
MyList = TheLinqQuery(TheParam);
var TheJson = new System.Web.Script.Serialization.JavaScriptSerializer();
string MyJson = TheJson.Serialize(MyList);
What I want to do is serialize only parts of MyObject. For instance, I might have Property1, Property2...Propertyn and I want MyJson to only include Property3, Property5 and Property8.
I thought of a way to do this by creating a new object with only the properties I want and from there create a new list for the serialization.

C# - Error Converting JSON To .Net Object?

C# - Declare And Use The Name Of A Function From A Json Object?
Apr 20, 2010I have a json object collection of geo locations that I build in the server. Each of those objects has two properties: "marker" and "onClick". Marker is for storing a Google Maps marker object and the onClick stores the name of the function to be called when that marker is clicked on the map.When I'm pushing the location objects into an array using javascript in the client side, I create the markers and assign them to each location object within the array.
My problem is that when I bind the marker with the onClick property, the function won't be found in the DOM and get an error.Is there a way to declare a property in a json object for using it on an event binding?

MVC :: JSON Object - Grid Is Not Filling Properly
Feb 25, 2011I've created a simple (or what I thought was simple!) search form using Razor, MVC3 and the webgrid from the web helpers. I enabled paging, used a great article I found here to get that working... or so I thought. Basically what happens is that when I click the page buttons at the bottom of the grid it does something that I didn't expect, and creates a JSON object, then the browser prompts me to try and save it, and not as I expected to refill the grid. I can't see what I'm doing wrong, and before I break my monitor by throwing it onto the railway line!

Deserialize Unnamed Json Array Into An Object In C#?

JQuery :: Creating JSON Object From AD Query
Mar 23, 2011I'm new to Jquery, JSON and MVC, and am trying to create a json object that contains AD info from an AD query. The ad query is working fine and returning data and I have 2 overloaded implementations of it.
#1 is a method from an older .net app that builds and returns a datatable that we bound to a grid view control
#2 was a modification of #1 that returns a System.Collections.Generic.List<> type. #2 returns data ok and i can display a table in the MVC view
however, I'd like to get the data results into a json object so i can bind it to a jqGrid object that has similar functionality to the old .Net server controls (Delete, Update, Sort) Here's the new method that's part of a C# static class:
