How To Pass JSON into asp.net MVC3 controller formatted like below

Question

I've read Phil's article ( http://haacked.com/archive/2010/04/15/sending-json-to-an-asp-net-mvc-action-method-argument.aspx ) and still can't figure out how I can take json that looks like what I have below and pass it into my controller. I don't have much control over formatting it so I need to take it like this and get the data out of it.

{
  "Id":"720",
  "SponsorName":"Bay Area Association of Database Developers",
  "ImageURL":"~/Images/Sponsors/baadd.org.jpg",
  "NavigateURL":"http://baadd.org/",
  "HoverOverText":"Bay Area Association of Database Developers",
  "Comment":"xx"
}

enter image description here

What is the repsonse from the server? I know it's 500 but you should get a stack trace. — Joe

can you please post code from you controller and the object you accept for your controllers input parameter. The names of the object properties and json properties need to match up exactly. — Evan Larsen

Hi Jakub, what you suggested worked pefectly! thanks. I also accidentally discovered that if I list out the parameters as follows, it also works. [HttpPost] public JsonResult Update(int id, string comment, string hoverOverText, string imageURL, string navigateURL, string sponsorName, string hasCurrentCodeCampYear) {
