Question

我尝试使用HttpClient每5秒向云端发送一次数据。我并不真正关心响应（可能只记录错误）并且想要异步发送它以免阻塞我的主线程。我使用的是以下功能。当我尝试单独的输入时它工作正常，但是一旦我进入5秒循环就停止工作（不能向云发送任何东西）

private static async Task SendToCloudAsync(Dictionary<string, string> dict)
    {
        var client = new HttpClient();
        client.BaseAddress = new Uri("some url");
        client.DefaultRequestHeaders.Accept.Add(
            new MediaTypeWithQualityHeaderValue("application/json"));


        foreach (KeyValuePair<string, string> kvp in dict)
        {
            var path = string.Format("variabels/{0}/values.json", kvp.Key);
            var request = new HttpRequestMessage(HttpMethod.Put, path);
            request.Content = new StringContent(kvp.Value);

            var response = await client.SendAsync(request);
        }
    }

然后在System.Timers.Timer触发的函数中，我就这么称呼它

timer.Enabled = true;
timer.Interval = 50000;
timer.SynchronizingObject = this
timer.Elapsed += new System.Timers.ElapsedEventHandler(this.someKindOfLoop);

private void someKindOfLoop(System.Timers.ElapsedEventArgs e)
{
    var dict = generateDict();
    var task = SendToCloudAsync(dict);
    // I also tried Task.Run(async () => { await sendToCloud(dict); });
}

我做错了什么建议？

C＃HttpClient每5秒异步发送一次数据到云端
