How do I read a section in JSON result by httpClient?

Question

这是检索 JSON 的 C# 代码：

try
        {
            HttpClient client = new HttpClient();
            client.DefaultRequestHeaders.Accept.Clear();
            client.BaseAddress = new Uri(_serviceConfig.DataGapsBaseUrl);
            var request = new HttpRequestMessage(HttpMethod.Get, "/piper/jobs/" + jobId.ToString() + "/status");

            var token = await GetToken();

            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
            var response = await client.SendAsync(request);
            var result = await response.Content.ReadAsStringAsync();
            var info = JObject.Parse(result);
            return true;
        }

如何提取返回的 JSON 中的这个特定部分（以黄色突出显示）？ Dfid 是该记录的唯一 ID。
