Question

在我的Xamarin应用中，我想设置计时器的计时器间隔，例如5秒后开始，并运行10秒。

这是我的代码示例

 let detxTag:XMLElement = XMLElement(name: "message")
 detxTag.addAttribute(withName: "id", stringValue: "mihir@gmail.com")
 detxTag.addAttribute(withName: "type", stringValue: "chat")
 detxTag.addChild(detxTag)

您可以在Device.StartTimer 5秒后添加System.Timers。

private static System.Timers.Timer aTimer;
static int count = 0;
public PageListView()
{
    InitializeComponent();

    Console.WriteLine("Timer prepare for running");
    Device.StartTimer(TimeSpan.FromSeconds(5), () =>
    {
        Console.WriteLine("Timer run");
        aTimer = new System.Timers.Timer(1000);
        // Hook up the Elapsed event for the timer. 
        aTimer.Elapsed += OnTimedEvent;
        aTimer.AutoReset = true;
        aTimer.Enabled = true;
        return false;
    });
}


private static void OnTimedEvent(Object source, ElapsedEventArgs e)
{
    count++;
    if (count==10)
    {
        aTimer.Stop();
        Console.WriteLine("Timer Stop");
    }
}

输出：

10-23 10:34:14.250 I/mono-stdout(29128): Timer prepare for running
10-23 10:34:19.262 I/mono-stdout(29128): Timer run
10-23 10:34:29.286 I/mono-stdout(29128): Timer Stop
