Parse Json string in C

Question

I m trying to read a Json string in C   but I m having trouble figuring out just how to parse the string into C   Say I have the following Json string                   AppName                  Description    Lorem ipsum dolor sit amet                Value    1                      AnotherAppName                  Description    consectetur adipisicing elit                Value    String                      ThirdAppName                  Description    sed do eiusmod tempor incididunt ut labore et dolore magna aliqua                Value    Text                      Application                  Description    Ut enim ad minim veniam                Value    100                      LastAppName                  Description    quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat                Value    ZZZ                      I want to parse that into an arraylist or dictionary  using a format like  descriptionList  AppName      Lorem ipsum dolor sit amet   valueList  AppName      1     I ve been toying around with Json Net but the examples I ve seen don t give me a clear idea of how I should do this  What s the best way to achieve this  Cant this be done like in jQuery  using a foreach statement

Instead of an arraylist or dictionary you can also use a dynamic  Most of the time I use EasyHttp for this  but sure there will by other projects that do the same  An example below   var http   new HttpClient    http Request Accept   HttpContentTypes ApplicationJson  var response   http Get  url    var body   response DynamicBody  Console WriteLine  Name  0    body AppName Description   Console WriteLine  Name  0    body AppName Value     On NuGet  EasyHttp

What you are trying to deserialize to a Dictionary is actually a Javascript object serialized to JSON  In Javascript  you can use this object as an associative array  but really it s an object  as far as the JSON standard is concerned   So you would have no problem deserializing what you have with a standard JSON serializer  like the  net ones  DataContractJsonSerializer and JavascriptSerializer  to an object  with members called AppName  AnotherAppName  etc   but to actually interpret this as a dictionary you ll need a serializer that goes further than the Json spec  which doesn t have anything about Dictionaries as far as I know   One such example is the one everybody uses  JSON  net  There is an other solution if you don t want to use an external lib  which is to convert your Javascript object to a list before serializing it to JSON   var myList         each myObj  function key  value    myList push  Key key  Value value         now if you serialize myList to a JSON object  you should be capable of deserializing to a List lt KeyValuePair lt string  ValueDescription gt  gt  with any of the aforementioned serializers  That list would then be quite obvious to convert to a dictionary   Note  ValueDescription being this class   public class ValueDescription       public string Description   get  set        public string Value   get  set

I m using Json net in my project and it works great  In you case  you can do this to parse your json     EDIT  I changed the code so it supports reading your json file  array   Code to parse   void Main         var json   System IO File ReadAllText   d  test json         var objects   JArray Parse json      parse as array       foreach JObject root in objects                foreach KeyValuePair lt String  JToken gt  app in root                        var appName   app Key              var description    String app Value  Description                var value    String app Value  Value                 Console WriteLine appName               Console WriteLine description               Console WriteLine value               Console WriteLine   n                        Output   AppName Lorem ipsum dolor sit amet 1   AnotherAppName consectetur adipisicing elit String   ThirdAppName sed do eiusmod tempor incididunt ut labore et dolore magna aliqua Text   Application Ut enim ad minim veniam 100   LastAppName quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat ZZZ   BTW  you can use LinqPad to test your code  easier than creating a solution or project in Visual Studio I think
