C# RestSharp不知道如何调用回调

我正在使用restsharp从我正在做的API中获取数据，我想创建一个名为ApiInterface的类，该类将在Xamarin Android、iOS、Windows中使用。。。调用API

这个类有它的RestClient和函数，它们将从代码的任何部分调用，因为它是一个单例

例如，我将有一个MainActivity.cs类似的东西。调用我的getData函数并处理我收到的数据

Button buttonListaIntereses = FindViewById<Button> (Resource.Id.myButton);

buttonListaIntereses.Click += delegate {
    ApiInterface.Instance.getData(response2=>
    {
        Intent displayMessage = new Intent(this, typeof(DisplayMessage));
        //Put info in Extra for the new screen.
        displayMessage.PutExtra("content", response2.Content);
        StartActivity(displayMessage);
    });
};

但是在APIInterface中，我希望获得像cookies这样的公共数据

public async void getData(Action <IRestResponse> onDone)
{           
    RestRequest request = new RestRequest("getData", Method.GET);

   //Execute ASYNC the rest request
    m_Client.ExecuteAsync (request, response =>
    {
        //Do my stuff with headers.
        string lCookie = response.Headers.ToList().Find(x => x.Name == "Cookie").Value.ToString();
       //Execute the OnDone
       onDone();
    });
}

我的问题是我不确定如何在getData中执行OnOne和/或如何调用getData函数

谢谢

操作参数onDone采用IRestReponse类型的参数：

操作参数onDone采用IRestResponse类型的参数：

我将不再使用回调，而是利用C的异步/等待特性

buttonListaIntereses.Click += async delegate {
    var response = await ApiInterface.Instance.getData();
    LaunchResponseActivity(response);
};

public void LaunchResponseActivity(IRestResponse response)
{
    Intent displayMessage = new Intent(this, typeof(DisplayMessage));
    //Put info in Extra for the new screen.
    displayMessage.PutExtra("content", response.Content);
    StartActivity(displayMessage);
}

public async Task<IRestResponse> getData()
{           
    RestRequest request = new RestRequest("getData", Method.GET);

    var cancellationTokenSource = new CancellationTokenSource();

    var restResponse = await client.ExecuteTaskAsync(request, cancellationTokenSource.Token);

    //Do my stuff with headers.
    string lCookie = restResponse.Headers.ToList().Find(x => x.Name == "Cookie").Value.ToString();

    return restResponse;
}

嗨，Andrés，我没有试过你的代码，我是新使用async/await c功能的人，它们的优点是什么？你是说最好改变xamarin的所有界面及其导航流程。嗨，Andrés，我没有试过你的代码，我是新使用async/await c功能的人，它们的优点是什么？你是说最好更改xamarin的所有界面及其导航流程。谢谢lenkan！我被它困住了！：谢谢lenkan！我被它困住了！：
