Passing complex JSON string to 1 parameter webmethod in c# - desearialize into object (json.net)?

Question

I have been happy serializing with javascript objects into JSON using ``` JSON.stringify ``` And sending along to my "static" webmethod in c#/asp.net and sure enought it arrives .. I need the correct number of parameters hence if my json object has "startDate","endDate","reserve" then my webmethod needs these as parameters. "Basically with my order object that i have, i have a number of parameters on this object so i would need to use the same number on the webmethod - this is a bit messy??" - I will explain I have a rather complex "Order" object in javascript and wish to serialize it using stringify and send it along to my webmethod but i don't want to specify all the parameters is there a way round this? I was hoping for something like this on my webmethod ``` public static bool MakeReservation(object order) ``` Then in my webmethod i only have 1 parameter BUT i can then desearilize this to a true c# object using JSON.NET. I have tried it like this sending the json across but becaus…

Accepted Answer

If you try to submit an object that looks like this:

```
JSON.stringify({ endDate: new Date(2009, 10, 10), startDate: new Date() });
```

it will try and map endDate and startDate to corresponding parameters in your webmethod. Since you only want to accept one single method, I suspect you may get away with it by submitting the following:

```
JSON.stringify({ order: orderObject });
```

Which it might reasonably try to assign as a value to the 'order' parameter of your webmethod. Failing that, submitting

```
JSON.stringify({ order: JSON.stringify(orderObject) });
```

and then deserializing it using JSON.NET should definitely work, but it's uglier, so try the first example first. That's my best shot.
