How to get specific value from JSON array using C#

I need help trying to extract "RiskID" value from the attached JSON using C# and Newtonsoft.

The response is JSON array and that is why I’m having some difficulty.

I tried to do some testing using below code but it is not working

JArray jArray = JsonConvert.DeserializeObject<JArray>(jsonstring);

                for (int i = 0; i < jArray.Count; i++)
                {
                    JArray jArray1 = JsonConvert.DeserializeObject<JArray>(jArray[i].ToString());
                    string key = ((JValue)jArray1[0]).Value == null ? "" : ((JValue)jArray1[0]).Value.ToString();
                    string value = ((JValue)jArray1[1]).Value == null ? "" : ((JValue)jArray1[1]).Value.ToString();
                    Response.Write(key + " : " + value +"<br>");
                }

Thanks for your help.

    you have to parse your json string to json array

        string[] riskIds = JArray.Parse(jsonstring)
                             .Select(a => a.SelectToken("Bur.RiskSummary.RiskId").Value<string>())
                             .ToArray();
                             
    string  riskId0 = riskIds[0];            
    string  riskId1 = riskIds[1];

    JArray jArray = JsonConvert.DeserializeObject<JArray>(jsonstring);

string[] valueArray = jArray.Select(p => p["Bur"]["RiskSummary"["RiskId"].ToString()).ToArray();

string value = string.Join(":", valueArray);`
