Cannot Parse Json sub object - asp.net

Question

I am using JObject to parse Json object below
string Jstring = #"{
"PolicyId" :"xxxxxx",
"PolicyHolder" :{"title":"Mr", "FirstName":"test", "LastName":"testLast"}
}";
I can get the PolicyId value through below code
Jobject jobj = Jobject.parse(Jstring);
string PolicyId = jobj.value<string>("PolicyId");
But, I always get null using below code:
string Holder = jobj.value<string>("PolicyHolder");
I have debugged the code below:
jobj.Properties()
I can find PolicyHolder in the List. I have tried code below also, the value is always null
JProperty jproperty = jobj.Properties().SingleOrDefault(x => x.Name == "PolicyHolder");
Can anyone know what happen?

Answer 1

string Holder = jobj.value<string>("PolicyHolder");
Above line fails because PolicyHolder is not string. You are trying to cast it to string. It's an object. You must create a class with the properties of the PolicyHolder and use that as a type instead of string.

Answer 2

Here's the working dotNetFiddle: https://dotnetfiddle.net/xOOl5m
Console Output:
Here are the classes I ended up declaring and using.
public class PolicyHolder
{
public string title { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
}
public class Policy
{
public string PolicyId { get; set; }
public PolicyHolder PolicyHolder { get; set; }
}
Like Sam has mentioned, PolicyHolder is an Object not a string.
Here's the complete code listing (so that the answer is self-contained).
