winform如何POST修改JSON格式中某个值 本人小白刚学1个星期只会用POST抓取想要的值，修改JSON中的值就没有思绪

	string strURL = "http://222.92.231.22:1816/api/v1/account/query";
				System.Net.HttpWebRequest request;
				request = (System.Net.HttpWebRequest)WebRequest.Create(strURL);

				//POST sign和需要抓取的参数
				request.Method = "POST";
				request.KeepAlive = false;
				request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
				string paraUrlCoded = "&sign=" + dd + "&account_number=" + aa.Text;
				byte[] payload;
				payload = System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);
				request.ContentLength = payload.Length;
				Stream writer = request.GetRequestStream();
				writer.Write(payload, 0, payload.Length);
				writer.Close();

				//读取全部数据
				HttpWebResponse response = (System.Net.HttpWebResponse)request.GetResponse();
				StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
				string ret = sr.ReadToEnd();
				sr.Close();
				response.Close();
				writer.Close();

				//反序列化
				Root provinceResult = JsonConvert.DeserializeObject<Root>(ret);

				foreach (Data jobInfo in provinceResult.data)
				{
					//抓取需要的参数
					int dat1 = jobInfo.user_concur_number;
					label1.Text = "" + dat1;
					string dat2 = jobInfo.install_address;
					label2.Text = dat2;
					DateTime dat3 = Convert.ToDateTime(jobInfo.expire_date);
					label3.Text = dat3.ToString();
					string dat4 = jobInfo.account_number;
					label4.Text = dat4;
					DateTime dat6 = Convert.ToDateTime(jobInfo.create_time);
					label6.Text = dat6.ToString();
				}

本人小白只会抓取数据，如何修改JSON中的某个值啊，求救，谢谢大佬们了

[XBodhi.]

你已经 Root provinceResult = JsonConvert.DeserializeObject<Root>(ret);

所以你直接 provinceResult. Method or Field = value; 即可。

然后 在 JsonConvert.SerializeObject(objcet obj);

第二种方法是 直接 匹配替换。
