restsharp 发出多异步请求

Question

用 restsharp.org 请求 API 很容易，但是当我需要调用两个不同的 API 时，第一个请求保存代码，第二个响应开始后，我认为这是不正确的，下面是我的代码：

var client = new RestClient("http://xxx.yyy.com/");

var requestHotels = new RestRequest("api/hotelUi/home/hotelList", Method.POST);
requestHotels.AddParameter("take", "16");                                               
IRestResponse hotels = client.Execute(requestHotels); 
List<Hotel> topHotels = JsonConvert.DeserializeObject<List<Hotel>>(hotels.Content); 

var requestCities = new RestRequest("api/hotelUi/home/cityList", Method.POST);
requestCities.AddParameter("take", "16");                                                 
IRestResponse cities = client.Execute(requestCities);
List<City> topCities = JsonConvert.DeserializeObject<List<City>>(cities.Content);

如您所见，城市请求等到酒店请求响应，但我认为它们都必须发送，并等到两个响应都返回。

我该怎么做？

评论是正确的，将 ExecuteAsync（它也可以反序列化数据 - 参见 http://restsharp.org/）与任务一起使用可能如下所示：

// Set up requests as before
var client = new RestClient("http://xxx.yyy.com/");

var requestHotels = new RestRequest("api/hotelUi/home/hotelList", Method.POST);
requestHotels.AddParameter("take", "16");  

var requestCities = new RestRequest("api/hotelUi/home/cityList", Method.POST);
requestCities.AddParameter("take", "16");     

var cancellationTokenSource = new CancellationTokenSource();

var hotelsTask = client.ExecuteTaskAsync<List<Hotel>>(requestHotels, cancellationTokenSource.Token);
var citiesTask = client.ExecuteTaskAsync<List<City>>(requestCities, cancellationTokenSource.Token);

var tasks = new List<Task> { hotelsTask, citiesTask };

// Pause execution here until both tasks are complete
await Task.WhenAll(tasks);

// Check status then use hotelsTask.Result and citiesTask.Result
