body: <p>I want help how to take text from response of http here the source of request</p>
  
  <pre><code>var request = (HttpWebRequest)WebRequest.Create("https://xxxx.com/");
  
          var postData = "{"+'"'+"get"+ '"' +":100}";
          var data = Encoding.ASCII.GetBytes(postData);
          request.Method = "PUT";
          request.ContentType = "application/json";
          request.Headers["X"] = "83ed3926";
  
  
          request.ContentLength = data.Length;
  
          using (var stream = request.GetRequestStream())
          {
              stream.Write(data, 0, data.Length);
          }
  
  
  
          var response = (HttpWebResponse)request.GetResponse();
  
          var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
  </code></pre>
  
  <p>now i want source code to can search in : responseString </p>
  
  <p>Example:</p>
  
  <pre><code>{"auctionInfo":[{"IDEF":224454585435,"itemData":2 ","buyNowPrice":100,"
  ,{"IDEF":224454839937,"itemData":","buyNowPrice":200,"{"IDEF":315779793672,"timestamp":1539055787,"formation":"f352","Price":100,"assetrd":1,"rating":","buyNowPrice":300,"
  </code></pre>
  
  <p>I want way to take the first IDEF and buynowprice and to add them to two strings.</p>
  
  <p>Example if will run the code will be:</p>
  
  <pre><code>IDEF = 224454839937
  
  buyNowPrice = 100
  </code></pre>
