{ "id":"3", "Name":"Sovrav" } ]}
Now i want to filter out only array from that JSON and store them in a variable like this :

I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.

[Code]....
As you can see that the code read the XML file and put it into a string array.
this array is 1000 cell length...
and that's my problem...
I want the array to be with dynamic size no limited one...

How do you store multi-dimensional array to viewstate? Here's what I did:
public bool[,,] regsettings = new bool[7,5,4];
bool[,,] regsettings = (bool[,,])ViewState["regsettings"]; // this line works!
regsettings[i,j,tab] = (bool)ViewState["regsettings"]; // this line no working?! The error is: Object reference not set to an instance of an object. The letters i,j, tab are just variables in the loop. They are there. I also tried: (bool[,,,]) as a cast and it is a no-go either.?

.I am using VS2010 Ultimate in an out of the box HelloWorld MVC2 ProjectI am using JQuery 1.4.1I have the following code in my View:
function TestStringArray() {
var stringArray = new Array();
stringArray[0] = "item1";
[code]...
Forgetting my controller actually needs to return a Json result (I have a break on the return View() line), the values parameter is null. When I pass in a single string (change the type from List<String> to String in the controller, pass in a single string value from the View), it works fine. Looking at Fiddler, the array is passing the multiple values.I did some research and people are suggesting JSON.Stringify ion the JSON2 library, the JSON.NEt library, etc... Do I really need extra libraries? Microsoft didn't think of this scenario for out of the box? I assume the problem is any kind of complex type.

I am getting an error when trying to serialize an object products.
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[3,2] { {"Small","40"}, {"Medium","44"}, {"Large","50"} };
string json = JsonConvert.SerializeObject(product);//this line is throwing an error
Array was not a one-dimensional array. Is there any way to serialize a two dimensional array with Newtonsoft.json.

Wondering how to deserialize the following string in c#:
"[{"access_token":"thisistheaccesstoken"}]"
I know how to do it if the json was:
"{array=[{"access_token":"thisistheaccesstoken"}]}"
I'd do it like this:
public class AccessToken
{
public string access_token {get;set;}
public DateTime expires { get; set; }
}
public class TokenReturn
{
public List<AccessToken> tokens { get; set; }
}
JavaScriptSerializer ser = new JavaScriptSerializer();
TokenReturn result = ser.Deserialize<TokenReturn>(responseFromServer);

I'm looking for a way to define and send a JSON object array. I've figured out how to define a single JSON object, turn it into a string and send it, but what about an array of this type? Probably something simple I'm overlooking...
var myColumnSetting = { "ColumnName": name,
"ColumnIndex": index
}
convert it to a string
var myJSONText = JSON.stringify(myColumnSetting, false);

I am trying to return some data as json from an action method.
I have an employee object that looks like this:
public class Employee
{
public int EmployeeID {get; set;}
public string FirstName {get; set;}
public string LastName {get; set;}
//Other irrelevant properties
}
Then I have a view model as follows
public Class EmployeeViewModel
{
public Employee Supervisor{get; set;}
public List<EmployeeViewModel> Employees
}
I need to return a json object that looks exactly like this:
{id: 1, name: John, children: [
{id: 1, name: Joe, children: []},
{id: 1, name: Rob, children: []}
]}
For now I only need to go to the second level as above, returning and supervisor and their staff members beneath them.
How would I go about returning this in my action method(I have the viewModel object hydrated already I just need to return it as json). My problem so far has been that the children property does not get populated.

I wish to store some variables across my whole ASP.NET site, such as the site name/title and a multitude of others.
I wish to store them in an XML file with a name and value, and then insert them into the relevant place on the page using a tag like <% siteTitle %>.
How can I do this? I have seen similar with sites like SmarterMail and other ASP.NET off-the-shelf products, but they seem to use a value from their own DLL file, this is probably too much of a complex method, so I will need something simple like the XML method mentioned above. Having said this, I don't particularly want to use the AppSettings method.
