錯誤使用C＃

Question

我嘗試使用下面的代碼來發佈一個以REST API使用WebClient的對象REST API調用：

string URI = "https://api.myTrade.com/s1/order/" + orderId; 
      string myParameters = "symbol=AAPL&duration=day&side=buy&quantity=1&type=limit&price=1"; 
      Console.Write("Parameters : " + myParameters + "\n"); 
      using (WebClient wc = new WebClient()) 
      { 
       wc.Headers[HttpRequestHeader.Authorization] = "Bearer " + token 
       wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded"; 
       wc.Headers[HttpRequestHeader.Accept] = "application/json"; 
       string responsebody = wc.UploadString(URI, myParameters); 
       //Console.Write("Output : " + responsebody + " "); 
       dynamic dynObj = JsonConvert.DeserializeObject(responsebody); 

       return responsebody; 
      } 

我得到以下異常：

Input String was not in a correct format. 

任何非常感謝幫助。
