C# Chaîne JSON Désérialisation

Je suis vraiment du mal à trouver des exemples de JSON Désérialisation en C#, où la première propriété dans chaque JSON élément est un ID différent.

    {
       "12112083":{
           "Topic_ID":"12112083",
           "Moved_ID":"51",
           "subject":"subject text goes here"      
           },
       "12111966":{
           "Topic_ID":"12111966",
           "Moved_ID":"51",
           "subject":"another subject text"      
           },
       "12106917":{
           "Topic_ID":"12106917",
           "Moved_ID":"0",
           "subject":"test"      
           }
    }

J'ai essayé différentes méthodes, sans succès. Le JSON retourné laquelle je n'ai pas le contrôle de l'est parfois un élément unique et parfois un tableau d'éléments, comme l'exemple ci-dessus. Idéalement, je voudrais désérialiser tapé dans un objet de la classe si possible.

J'ai essayé l'exemple de code fourni passer à la chaîne suivante

    '{"12112083":{"Topic_ID":"12112083","Moved_ID":"51","subject":"Due to a computer virus, many of my files are \u005C"Crypted\u005C",espe","Start_date":"10/6/2012 6:54:37 PM","InitialResponseDueDate":"10/6/2012 7:01:37 PM","Locked":"0","QValue":"$10","Status":"1","Author_ID":"71318191","Question_Text":"Due to a computer virus, many of my files are \u005C"Crypted\u005C",especially my pictures.  Now my FinepixA500 camera will not upload photos to my computer (laptop).  Geek Squad could not crack the code and suggested that I contact Toshiba and have them reset the computer to its original manufacturer settings.  If I do that, I will lose all of my data.  The only thing that appears not to be working is \u005C"photo gallery\u005C". (therefore, my camera will not upload photos anymore.....)

J'ai reçu le "InvalidCastException", Incapable de convertir l'objet de type 'System.Chaîne' de type 'Newtonsoft.Json.Linq.JObject'.

J'ai essayé de supprimer les guillemets simples de début et de fin de la chaîne mais j'ai reçu le même message?
