Question

I am just trying to shift some comma separated numbers to the frontend:

[AcceptVerbs(HttpVerbs.Get)]
public JsonResult GetSquares()
{
 var result = new JsonResult();
 result.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
IList<double> list = new List<double>();
...
result.Data = list;
return result;
}

This works fine as long as there are only a few numbers. Unfortunately, I have to shift lots of numbers occasionally and get a MaxJsonLength exception. I tried several suggestions to overcome this (add something to the web.config file etc.). Maybe I do not have to use JSON after all? However I still ‘have to do something’ with the numbers using javascript. I am using jquery’s ajax stuff at the moment.

Any suggestions welcome …

This won’t work?

<configuration> 
   <system.web.extensions>
       <scripting>
           <webServices>
               <jsonSerialization maxJsonLength="2147483644"/>
           </webServices>
       </scripting>
   </system.web.extensions>
</configuration> 

If not maybe you can just pass it back as a string…

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult GetSquares()
{
    IList<double> list = new List<double>();
    ....
    return Content(string.Join(",", list));
}
