C# - How To Convert Json Object To Custom Class Object In Web Service
Aug 30, 2010
I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?

Is there an easy way to populate my C# Object with the JSON object passed via AJAX?
//This is the JSON Object passed to C# WEBMETHOD from the page using JSON.stringify
{"user":{"name":"asdf","teamname":"b","email":"c","players":["1","2"]}}
//C# WebMetod That receives the JSON Object
[WebMethod]
public static void SaveTeam(Object user)
{
}
//C# Class that represents the object structure of JSON Object passed in to the WebMethod
public class User

public string name { get; set; }

public string email { get; set; }
public Array players { get; set; }

For my ASP.Net application I need to use a HTTP REST API that returns a JSON object.Here's how the JSON looks:
message: [
{
type: "message"
href: "/messages/id/23"[code]....
I could use the DataContractJsonSerializer Class and have custom Classes defined. However, am not sure how keys like "$" would get converted to in .Net.

I just hit the following issue: I am calling a web service that returns a serialized JSON object let's say: __type, FirstName, LastName (.net object Person with properties FirstName and LastName). __type's value is Test.Person
I have created a JS object using Type.registerNameSpace/registerClass called Demo.Person and it is registered on the page using the ScriptManager. Everything is working fine; I am able to get data from the server on the call back.
Is it possible to make the returned object from the web service be an instance of the declared JavaScript Demo.Person class? The idea would be to call a method like result.getFullName() on the client side without having to copy all the properties. This is just a simple scenario for more complex objects.

I'm kinda new to web services and want to make sure I am doing things correctly.
I have a custom object which has sub objects as well. (let's say Company object, sub object is collection of Employee objects)
I want the web service to return a collection of Company objects. Do I make the service return a Dataset and custom generate a dataset with datatables representing the different objects?
What is the best way to do this? I tried to just serialize it, but that doesn't seem to work either.
I tried this dll
[URL]
But the output XML doesn't seem to include the sub object.

I'm writing messages to a Message Queue in C# as follows:
ObjectMsg objMsg = new ObjMsg(1,"ascii",20090807);
Message m = new Message();
m.Formatter = new BinaryMessageFormatter();
m.body = objMsg;
queue.Send(m);
and I'm trying to read the messages as follows:
Message m = new Message()
m.Formatter = new BinaryMessageFormatter();
MessageQueue mq = new MessageQueue("./pqueue");
m = mq.Recieve();
ObjMsg msg = (ObjMsg )m.Body;
However I'm getting an error message which says: "Cannot find a formatter capable of reading this message."

I have a custom class declared as follows (in vb.net)
<Serializable()> _
Public Class NumInfo
Public n As String
Public f As Integer
Public fc As char()
Public t As Integer
Public tc As char()
Private validFlag As Boolean = True
Public Sub New()
End Sub
I also have public properties(read/write) for all the public variables
End Class
In my service.asmx codebehind class I have a webmethod as follows:
<WebMethod> _
<XmlInclude(GetType(NumInfo))>
Public Function ConvertTo(ByVal info As NumInfo) As String
Return mbc(info)
'mbc is another function defined in my service.asmx "service" class
End Function
The problem is that when I start debugging it to test it, the page that I get does not contain any fields where I could input the values for the public fields of numInfo. How do I initialise the class? There is no "Invoke" button either. All I see are soap details as below:
ConvertTo
Test
The test form is only available for methods with primitive types as parameters. SOAP 1.1 The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values.
POST /BaseConverter/BaseCon.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://RohitServices.in/ConvertTo"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ConvertTo xmlns="http://RohitServices.in/">
<info>
<n>string</n>
<f>int</f>
<fc>
<char>char</char>
<char>char</char>
</fc>
What am I doing wrong? For the record I tried replacing char() with string to see if it was the array causing problems but that didn't help either. I'm fairly new to web services. I tried replacing the custom object parameter with a primitive parameter just to check how things worked and it rendered a page with an input field and invoke button. I just can't seem to get it working with custom object.

I could really use some help on this one. I've been fighting it now for several days and we are supposed to start testing early next week.I am subscribing to 4 web services all hosted by the same company. The integration with 1, 2 and 3 all went fine, but on the fourth I keep getting the very unhelpful error:
System.Web.Services.Protocols.SoapException = {"Server was unable to process request. ---> Object reference not set to an instance of an object."}

I have some javascript code that processes json output from asp.net web services built with framework 2.0. Now I need to support data returned from framework 3.5 web services. My javascript code assumes a list of objects as return value, which works fine in 2.0. However In framework 3.5, the list is wrapped in a "d" object. Is there any way I can remove the "d" wrapper and just return the list?

We are trying to consume WCF service which returns employee details in JSON Format.
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:
Dim serializer = New DataContractJsonSerializer(GetType(List(Of Employee)))
Dim memoryStream = New MemoryStream()
Dim s = msg.Content.ReadAsString()
serializer.WriteObject(memoryStream, s)
memoryStream.Position = 0.......

I 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.

I 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.
