C# HttpClient StreamContent用法

//var url = "http://demo.com/api/streamcontent";
//var item =new MyClass();
 HttpClient httpClient = new HttpClient();
 using (HttpRequestMessage request = new HttpRequestMessage())
  {
       request.Method = HttpMethod.Post;
       request.RequestUri = new Uri(url);

       using (MemoryStream ms = new MemoryStream())
       {
           //使用二进制序列化将你需要转送的对象转换成Stream
           BinaryFormatter binaryFormatter = new BinaryFormatter();
           binaryFormatter.Serialize(ms, item);
           ms.Position = 0; //重置ms的position，便于StreamContent读取流内容
           request.Content = new StreamContent(ms, (int)ms.Length);
           var res = httpClient.SendAsync(request).Result;
           res.EnsureSuccessStatusCode();
           //处理返回结果
       }
   }
