I'm using Json.NET and I'm trying to create a JSON string representing a row from a database table to return in an HTTP response. I'm not sure how to do this while I'm reading from the database.The problem is marked by the obnoxious comments /******** ********/
// connect to DB
theSqlConnection.Open(); // open the connection
SqlDataReader reader = sqlCommand.ExecuteReader();

why the following code doesn't work?
internal static string[] GetToolsForRole(string selectedRole) {

I use the JavaScriptSerializer class of ASP.net to serialize my object and return it to the client side. How can I deserialize the string using JavaScript?
View 4 RepliesIn 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.
public class Package
{
public Package()
{
name = "";
type = new List<Dictionary<string, string>>();
}
public string name { get; set; }
public List<Dictionary<string, string>> type { get; set; }

I try to use the jquery + json to get all elements in form and build a JSON var to post in a ASP.NET MVC method.
[Code]....
It method get all fields in a form and build a JSON, but it dont put JSON inside JSON.
Example:
If i have the follow form:
<input name="person.name"><input name="person.age"><input name="person.address.street">
The serialized string build a JSON like this
{ "person.name": "??", "person.age": "??", "person.address.street": "??" }
I need a plugin or some function to generate like this:
{ "person": { "name" : "??", "age" : "??", "address":{ "street": "??" } } }
I am getting this JSON string from an ASP.Net webservice:

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();

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?
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
{

I have some stored JSON strings stored in the DB which I want to return to the client as JsonResult . I know that Json(object) turns an object into JsonResult but what if I already have the result in a string ? can I cast it to JsonResult

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)
{
$.ajax({
type: 'POST',[code].....
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.
View 7 RepliesHow do I bind a result from a JSON string to a dropdownlist (I have 2 fields), "NAAM" should be DataTextField and "CODE" should be the DataValueField. Using ddl.Items.Add doesn't do the trick.

this is the web method I'm using to convert my DataTable into JSON string:
[Code]....
But I'm not sure this is as good and as fast as it should be. I am sending to client side a JSON string format, but I think maybe there is a better way of doing this. I know there is JSON.NET
but I didn't see there any converting for DataTables.
I need to make an API call to a url giving it a json string in this format (ignore the line numbers, of course):
Code:
1. {
2. "properties": [
3. {
4. "property": "email",
5. "value": "new-email@hubspot.com"
6. },
[Code] ....
I want to create a class with these properties so I can call a method for each record in our database and plug in the email, firstname, etc. I am having trouble with it because of the repetition of "property" each time. In other words, it doesn't fit the mold of this example I found:
Code:
using System;
using System.Web.Script.Serialization;
public class MyDate
{
public int year;
[Code] ....
which produces:
Code:
{
"firstName": "Markoff",
"lastName": "Chaney",
"dateOfBirth": {
"year": 1901,
"month": 4,
"day": 30
}
}
We are trying to fill JqGrid in ASP.NET MVC3 application where datatype is set to 'jsonstring' and in it's action controller, we set the json data string in ViewData and retrieve the same in javascript function where we used it to fill the Jqgrid.
// Action code
[Code]....
// Javascript code to fill Jqgrid
[Code]....
[Code]....
There is an error while filling grid and when i alert the data it shows " in place of " in data, as below.
{{"total":2,"page":1,"records":2,"rows":[{"RequestID":"1","cell":["CPU","DELL OptiPlex 745","DELL","OptiPlex 745","5"]},{"RequestID":"2","cell":["CPU","TOSHIBA Tablet Portege 3500","TOSHIBA","Tablet Portege 3500","10"]}]}
[data displays fine on this post :) ]
The decodeURI function do not work on strData and it always show " in place of " in the data. We do not want to replace the " with " in a loop as it slow the page with large data.
I am really struggling deserializing a PHP json encoded string in ASP.NET.I am using nusoap and CakePHP 1.3 on the PHP side and mvc.net 4.0 on the web service side and everything was working well. However, I couldn't figure out how to pass a complex array as one parameter of the webservice, so I had the idea of serializing it as json and passing a simple string. So far so good...
$args['products'] = json_encode($booking['Booking']['prs_products']);

As it is now I create a JavaScript object and then stringify it, put it in a hidden textbox and my code behind can read this string. I then use JSON.NET to parse the string which works fine. I now try to use ajax to post it to my web service but have some issues with how to send the string. I have tried many ways but gets the common errors like
Invalid JSON primitive: myString.
So I checked this out [URL] and it works with hard coded values but I want to use a variable.
JavaScsript to create the object:
for (var i = 0; i < results.rows.length; i++) {
var row = results.rows.item(i);
var customer = new Object();
customer.id = row['id']
customer.name = row['name']
var customerString = JSON.stringify(customer);
$.ajax({
type: "POST",
url: "synchronise.asmx/synchroniseCustomers",
data: "synchroniseCustomers: " + customerString,
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (xhr, status) {
alert("An error occurred: " + status);
},
success: function (msg) {
alert("success");
}
});
}
WebMethod:
public void synchroniseCustomers(string customerString)
{
JObject o = JObject.Parse(customerString);
string id = (string)o["id"];
string name = (string)o["name"];
If I use data: '{ FirstName: "Dave", LastName: "Ward" }'
in the example above it works but I wish to pass on a string instead.
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"}
DataContractJsonSerializer this is nice class added in the .net framework which can be used to serialize/desirealize object into JSON.
Now following is the example i am trying
[Serializable] class User { public string name; public string userId; }
Now following is the output generated
Output : Notice structure where only "name" is expected instead of k__BackingField
Now this is the problem after digging so much i am not sure from where <> and _BackingField is coming ?
{
"<name>k__BackingField":"test user",
"<userId>k__BackingField":100001}
