如何从HttpClient解析JSON字符串？

通过调用外部API，我得到了一个JSON结果。

HttpClient client = new HttpClient();
client.BaseAddress = new Uri(url);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = client.GetAsync(url).Result;
if (response.IsSuccessStatusCode)
{
    var result = response.Content.ReadAsStringAsync().Result;
    var s = Newtonsoft.Json.JsonConvert.DeserializeObject(result);
    return "Success";
}
else
{
    return "Fail";
}

在代码行`var s = Newtonsoft.Json.JsonConvert.DeserializeObject(result);`中，我得到的结果如下：

{

"query": "1",

"topScoringIntent": {

"intent": "1",

"score": 0.9978111,

"actions": [

{

"triggered": false,

"name": "1",

"parameters": []

}

]

},

"entities": [],

"dialog": {

"prompt": "1",

"parameterName": "1",

"parameterType": "1::1",

"contextId": "11",

"status": "1"

}

}

我正在使用`HttpClient`。我在访问`dialog`中的`prompt`键值时遇到了困难。我想要获取`dialog`中的`prompt`值。我该如何获取？
