Newtonsoft JSON JsonConvert.DeserializeObject problem

Hi,

I have a strange problem. I have a Web Api containing a products catalog.
When I load all the products into a datagridview object by usng:

C#

_products = JsonConvert.DeserializeObject<List<Product>>(result.Result);

Everything runs fine. When my result only contains 1 product the above line throws an exception that it cannot set the JSON to an object.
So I then have to use:

C#

Product product = JsonConvert.DeserializeObject<Product>(result.Result);

How to avoid this exception? I now start to deserialize to a List<> object and when the exception occurs I deserialize to the object, clean my list, ad my 1 value and my datagridview shows me desired product.
How to detect the number of items in the JSON string? Any other setting needed?

Regards,

Herman

This is a commercial product with some free version, but not open-source. I see no need to use it, but if you want it, you probably need to address to their customer support. There is open-source JSON.NET, and there is .NET FCL with JSON support.

There is no support section on their website.....
Product has MT license, so free for commercial use

Newtonsoft == JSON.NET :)
http://www.newtonsoft.com/json[^]

Only "JSON.NET Schema" requires a license.

Is this the same or not: https://json.codeplex.com?
It looks like it was moved from Newtonsoft and because open-source, but Newtonsoft still charges for it a for a commercial product. Is that so?

It's the same.

The CodePlex site has a link to the new home on GitHub:
https://github.com/JamesNK/Newtonsoft.Json[^]

The GitHub page links to the home page:
http://www.newtonsoft.com/json[^]

They both link to the blog:
http://james.newtonking.com/[^]

Newtonsoft doesn't charge for JSON.NET, only JSON.NET Schema, which is a separate product.

All right thank you. That blog could be another source of information for our inquirer.
