How to parse / deserialize JSON returned from holiday service in C #

Question

I get JSON in string format from a URL whose structure is similar to this, but I cannot parse it. This throws an exception, any idea how to parse it?

Here is the structure:

{
   "pathway":{
      "patients":{
         "patient":[
            {
               "patientid":"7703176",
               "name":"Abbot, Bud",
               "status":"Invited",
               "start":"2013-12-07",
               "last":"N/A",
               "engagement":"N/A",
               "drug":"N/A",
               "adherence":"N/A",
               "vitals":"Current",
               "last_appointment":"2013-10-25",
               "next_appointment":"None"
            },
            {
               "patientid":"5089554",
               "name":"Brennan, Bonnie",
               "status":"Connected",
               "start":"2013-12-29",
               "last":"2014-02-01",
               "engagement":"Low",
               "drug":" ",
               "adherence":" ",
               "vitals":"Out of Date",
               "last_appointment":"2013-04-21",
               "next_appointment":"None"
            }
         ]
      }
   }
}

I do like this:

public class PathWayWrapper
{
    public pathway pathway { get; set; }
}

and

public class pathway
{
    public List<patient> patients { get; set; }
}

and

public class patient
{
    public long patientid { get; set; }
    public string name { get; set; }
    public string status { get; set; }
    public string start { get; set; }
    public string last { get; set; }
    public string engagement { get; set; }
    public string drug { get; set; }
    public string adherence { get; set; }
    public string vitals { get; set; }
    public string last_appointment { get; set; }
    public string next_appointment { get; set; }
}

here is my syntax code:

StreamReader reader = new StreamReader(response.GetResponseStream());

string json = reader.ReadToEnd();

var Jsonobject = JsonConvert.DeserializeObject<PathWayWrapper>(json);

objPathway = Jsonobject.pathway;

The classes you are deserializing into are incorrect. You are missing the Patients class.

JSON , http://json2csharp.com, . , .

var jsonobject = JsonConvert.DeserializeObject<RootObject>(json);

public class Patient
{
    public string patientid { get; set; }
    public string name { get; set; }
    public string status { get; set; }
    public string start { get; set; }
    public string last { get; set; }
    public string engagement { get; set; }
    public string drug { get; set; }
    public string adherence { get; set; }
    public string vitals { get; set; }
    public string last_appointment { get; set; }
    public string next_appointment { get; set; }
}

public class Patients
{
    public List<Patient> patient { get; set; }
}

public class Pathway
{
    public Patients patients { get; set; }
}

public class RootObject
{
    public Pathway pathway { get; set; }
}
