Thanks, R) Rick Strahl August 20, 2013 # re: Using JSON.NET for dynamic JSON parsing @richard - that code works for me and all tests pass. Rick Strahl June 23, 2013 # re: Using JSON.NET for dynamic JSON parsing @Aviv - Are you sure you're casting to dynamic first?

I was able to send the code via JSON. This means you can assign properties by string, which can be useful for fully data driven JSON generation from other structures. Is the JObject not populated? Yes it does seem odd to include npm from an npm dependency in such a way doesn't it. http://stackoverflow.com/questions/15192226/deserialize-json-to-dictionary-using-linq-to-json

We've been chatting with npm lately and we have a msft contributor on node core.

But vstools updater was choking on some inner dependency of that 'recent' npm. I posted some feedback in the forum a week or two ago that this is not working as expected.

It has taught me a new way to parse JSON. On 1941 Dec 7, could Japan have destroyed the Panama Canal instead of Pearl Harbor in a surprise attack? First Skills to Learn for Mountaineering Are 14 and 21 the only "interesting" numbers? I think the next version of the Azure Storage library will clear that one up.

Alternately you can also go to the CodePlex site and download the latest version including source code: http://json.codeplex.com/ Creating JSON on the fly with JObject and JArray Let's start with creating https://github.com/aspnet/Mvc/issues/4349 The duplicate string seems to be causing the error, but I don't have any good idea on how to resolve it.This code was working well until the addition of the new Note that you can also access the JObject instance directly (not as dynamic) and get access to the underlying JObject type. What now?

When you receive or return a JObject, JValue, JToken or JArray instance in a Web API method, Web API ignores normal content negotiation and assumes your content is going to be this content Version 3.5, when I used the nuget version 4.5 the error goes away. I have to either assign the dynamic value to a variable as I did above, or explicitly cast ( (string) json.Name) in the actual method call. I truly hope that this thread is helping your team get to a more stable RC2 or at the very least serves as a place where others running into the same

I wrote about dynamic JSON parsing a few months back before JSON.NET was added to Web API and when Web API and the System.Net HttpClient libraries included the System.Json classes like kwaclaw referenced this issue in dotnet/cli Mar 25, 2016 Closed Newest build (2019) seems to break ASP.NET #2061 aspnet member Eilon commented Mar 25, 2016 Oh so it's not a real Try this (I made your JSON an array and added a second object): string json = "[{ \"PrintId\":10,\"Header\":\"header\",\"TC\":\"tc\",\"CompanyRef\":\"00000000-0000-0000-0000-000000000000\"}" + ",{ \"PrintId\":20,\"Header\":\"header2\",\"TC\":\"tc2\",\"CompanyRef\":\"00000000-0000-0000-0000-000000000000\"}]"; var objs = JsonConvert.DeserializeObject>(json); //The loop is only for testing. weblink Lack of effective tools in FoxPro to parse make this tough and perf is a problem as well since VFP has no efficient way to parse character by character.

Additional information: 'Newtonsoft.Json.Linq.JObject' does not contain a definition for 'AlbumName' This occurs at "album.AlbumName = "Dirty Deeds Done Dirt Cheap"; " in fragment below [TestMethod] public void JObjectOutputTest() { // strong Each example on internet use an string which parse and cast to JObject end then getting the values with the ["stringket"] my problem is I am geeting that value as a JSON.NET is vastly more flexible than the built in DataContractJsonSerializer or the older JavaScript serializer.

The JSON was in a wrong formatted.

I'm not even sure how to go back to We're working on updating to a newer version, but we using versions that we haven't tested (especially when the CLI is churning so much) is probably not a good idea. Instead I could pull out the three or four values I needed from the API and directly store it on my business entities that needed to receive the data - no The JSON structure can be much more complex than this simple example.

Sometimes it just makes lot of sense to pull just a small amount of data out of large JSON document received from a service, because the third party service isn't directly You can add it to your project with: PM> Install-Package Newtonsoft.Json From the Package Manager Console or by using Manage NuGet Packages in your project References. The file may be parseable JSON but may contain objects with duplicate properties.
