c# - 销毁异步 void

Question

我正在使用 Xamarin 和 C#。当我销毁一个活动时，我观察到 async void 仍在运行。

protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);

    SetContentView(Resource.Layout.TableItemsMain);
    RefreshTableAsync();
}

async Task RefreshTableAsync()
{
    using (var client = new HttpClient())
    {
        client.Timeout = TimeSpan.FromMilliseconds(10000);
        var response = await client.PostAsync("http://" + MyIp + ":9090/", new StringContent("2:" + MyTableName + "", Encoding.UTF8, "application/json"));

        if (response.IsSuccessStatusCode)
        {
            string content = await response.Content.ReadAsStringAsync();

        }
    }
}

如何在销毁时处理我的异步 void？
