Is there a way to get list of specific element in JSON using C# and Newtonsoft

Im trying to get a list of all the "Occupants" and "RiskId" from the JSON below using C# and Newtonsoft.

Not sure what I’m doing wrong here. Thanks for your help.

{
    "Header": {
        "MatchType": "Exact",

                }

                    "PostalCity": "MONTEBELLO",
                    "State": "CA",
                    "Zip": "90640",
                    "Zip4": "5225",
                    "County": "LOS ANGELES"
                },
                "AlternateAddresses": []
            },
            "Occupants": [
                {
                    "Name": "MFG STORAGE - PACKAGING MATERIALS",
                    "OccupantId": "15"
                }
            ],
            "ProductListUrl": "https://prometrixapiuat.iso.com/uw/Risk/64CX99016400/ProductList",
            "YearBuilt": 1960,
            "FireProtectionArea": "MONTEBELLO"
        }
    ]
}

I would just like to loop through the list of "RiskId" and "Occupants" and display the value.

If I do ….

var jsonObj = (JObject)JsonConvert.DeserializeObject(jsonstring);

var jsonResult = jsonObj.SelectToken("Risks.RiskId").Select(m => m.Value<string>());

I’m getting below error

System.ArgumentNullException: ‘Value cannot be null.
Parameter name: source’

>Solution :

I showed you this kind of code yesterday

JArray risks = (JArray) JObject.Parse(jsonstring)["Risks"];

var riskId = risks.Select(r => (string) r["RiskId"] ).FirstOrDefault(); // "64CX99016400"
    
JArray occupants = risks.Select(r => (JArray) r["Occupants"] ).FirstOrDefault());

UPDATE

after @dbc update, if you can have several risks items, just remove firstordefault()

string[] riskId = risks.Select(r => (string) r["RiskId"] ) 

Response.Write(string.Join(",",riskId)); //"64CX99016400"

JArray occupants = risks.Select(r => (JArray) r["Occupants"] );
