JSON Serialization Of C# Enum As String?
Mar 14, 2010
I have a class that contains an enum property, and upon serializing the object using JavaScriptSerializer, my json result contains the integer value of the enumeration rather than its string "name". Is there a way to get the enum as a string in my json without having to create a custom JavaScriptConverter? Perhaps there's an attribute that I could decorate the enum definition, or object property, with?As an example:
enum Gender { Male, Female }
class Person
{
[code]...

I am using .Net Framework 3.5 on an ASP.net web project using jquery.ajax to make web service calls. My web service returns objects serialized as JSON by specifying the content type of my POST as "application/json". I would like just one of my many properties to return a non quoted javascript function name instead of a quoted string. Serialized as such:
{"dataInit": functionName, "id": "myID"}
instead of
{"dataInit": "functionName", "id":"myID"}

I'm trying some WCF ajax.net 3.5 out for the first time, and I'm having some difficulties. I have a WCF Service which I have connected to in my aspx page using <asp:ScriptManager>. I have a custom object which has been decorated as a [DataContract]. I'm calling the object from javascript successfully, I can see the JSON response in FireBug, but Sys.Serialization.JavaScriptSerializer.deserialize() chokes on it. I'm sure I'm making a noob mistake, but I used up all my patience getting the Web.Config values right for running the WCF service.
Here's a mockup of what I'm doing.

Why this WCF 3.5 method
[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Json
{
[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json)]
public string Upper(string text)
{
return text.ToUpper();
}
}
returns {"d":"TEXT"} ?
It should returns {"TEXT"}
I'm calling using jQuery.
$("#upper").click(function() {
$.ajax({
type: "GET",
url: "/Json.svc/Upper?text="+$("#input1").val(),
success: function(data) {
$("#input1").val(data.d);
}
});
});

in Json.net we can rename the property with [JsonPropertyAttribute("")] ,
public class Foo
{
// how can I rename the Foo1 property name to F1?!
public string Foo1 { set; get; }
public string Foo2 { set; get; }
}
and in the web service code behind :
[WebMethod]
public List<Foo> GetFoos()
{
List<Foo> post = new List<Foo>
{
new Foo(),
new Foo(),
new Foo()
};
return post;
}

I want to use the DataContractJsonSerializer class. This is contained within theSystem.Runtime.Serialization.Json namespace and the System.ServiceModel.Web dll.or some reason, when I add the using directive for the namespace, Visual Studio says it doesn't recognise the Json namespace in System.Runtime.Serialization.When I try to add the System.ServiceModel dll, nothing happens, which suggests to me it's already referenced. (Because nothing also happens when I try to add a reference to System.Web which is definitely referenced!)

I'm getting the error from the subject line when I try to move some code that formerly lived in the App_Code directory to an external library (that would be moved into the /bin directory). What do I need to include or reference to get rid of this error?
I've already included: System.Runtim.Serialization (says it's version 3.0.0, I don't see a version 3.5.0 anywhere).

In my javascript code I am getting json string from cs file
var tmpString="<%=resultset2%>";
In cs I am concatenating strings to build json string. Here is an issue the json string is returned as a string and it has " with it.
"[{id:'1',name:'Aik'},{id:'2',name:'Aik or Aik'}]"
Because of " in beginning and end javascript code treat it as a string.

{"d":{"Table":[{"col1":123,"col2":"name","col3":"name","col4":100,"col5":"/Date(1153033200000)/"},{"col1":123,"col2":"name","col3":"name","col4":101,"col5":"/Date(1153033200000)/"},{"col1":123,"col2":"name","col3":"name","col4":102,"col5":"/Date(1153033200000)/"}]}}
In my jQuery how do I reference the Table code so I can loop through the data?
msg.d[i].col1
What am I missing? msg.d.table[i]?

I am developing a webiste in ASP.NET. On one of the pages page named menu.aspx, with the help of a certain login, I am getting the output in this format
foo({"1":"Jeff","2":"Mik","5":"Tom"});
I am using this code to get the output on the JSON form.
[Code]....
However, I must get the output only in simple JSON on the page without any HTML.
For eg: Here's the screenshot showing the source of the output page. [URL]
Notice that it has only the JSON string as the output.
And here's the screenshot showing the output page source (with HTML). [URL] .This HTML is what I have to remove. How can do I do this? The full code of menu.aspx.cs is putup here. [URL]

System.Web.Script.Serialization.JavaScriptSerializer s = new System.Web.Script.Serialization.JavaScriptSerializer();
result = s.Deserialize<Hashtable>(data);
Error is thrown if data is "{a:""test" 123",b:"hello" }"
No error is thrown if data is "{a:"test 123",b:"hello" }"
How do I adjust the data string so that no error is thrown even when there are quotes?

how to pass this via Json.Tried doing something like
var data = { Item1: "test", Item2: 5 };
var JSONdata = $.toJSON(data);
However that did not work. Although simply changing wcf to expect an object with two properties such as Item1 and Item2 will work. Here is example I'm using... I'll trim it a bit to make it easier to read:
function Post(data, url)

So I'm writing an MVC application, and have a JsonResult post back to obtain some item information for scanned items on a warehouse application I am writing. I'm trying to obtain a URL query string value though, and cannot seem to obtain one via the normal 'Request.QueryString['variable']' way... Is there a way to do this? I also thought about just passing the parameter into my post, but I already have a single value on my jquery post, and I am unsure if I can tack on more values to this.
