Error with await operator

Question

There is problem with my code. How can I solve this problem? This problem in await operator.

 public MyModel() 
    {
        HttpClient client = new HttpClient(         


        

Answer 1

You can't use await in the constructor of a class.

An async method returns a Task object which can be executed async. A constructor does not have a return type and thus can't return a Task object, and thus can't be awaited.

A simple fix for this problem is create a Init function:

public MyModel() 
{

}

public async Task Init()
{
    HttpClient client = new HttpClient();
    HttpResponseMessage response = await client.GetAsync("https://api.vkontakte.ru/method/video.get?uid=219171498&access_token=d61b93dfded2a37dfcfa63779efdb149653292636cac442e53dae9ba6a049a75637143e318cc79e826149");
    string googleSearchText = await response.Content.ReadAsStringAsync();
    JObject googleSearch = JObject.Parse(googleSearchText);
    IList results = googleSearch["response"].Children().Skip(1).ToList();
    IList searchResults = new List();
    foreach (JToken result in results)
    {
        MainPage1 searchResult = JsonConvert.DeserializeObject(result.ToString());
        searchResults.Add(searchResult);

    }
}

Then when you create your model:

var model = new MyModel();
await model.Init();
