启动DispatcherTimer的代码。

我只需要检测任何类型的用户Ineraction以重启DispatcherTimer？

[WebMethod]
    public string[] GetCompletionList(string prefixText)
    {
        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["dbconnection"].ToString());
            con.Open();
            SqlCommand cmd = new SqlCommand("select Company_name from Outword_CommonMST where Company_name  " +
                                                            "like '" + prefixText + "%' order by company_name", con);
            //cmd.Parameters.AddWithValue("@Name", prefixText);
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataTable  dt = new DataTable( );
            da.Fill(dt);
            List<string> Company_name = new List<string>();
            for(int i=0;i<dt.Rows.Count;i++)
            {
                Company_name.Add(dt.Rows[i][0].ToString());
            }
            return Company_name.ToArray();
        }
    }

如何检测任何类型的用户交互以触发restartTimer（）方法？

我在每个PhoneApplicationPage的Tap上添加了一个事件。

int timeOutInSeconds;
Timer timerObject;

 private void onPageLoad()
 {
   timeOutInSeconds = 30;
   timerObject = new Timer();
   timerObject.startTimer(this, timeOutInSeconds, appsettings);
 }
private void LayoutRoot_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
   timerObject.restartTimer(timeOutInSeconds);
} 

 public class Timer
{
    public DispatcherTimer dispatcherTimer;
    public PhoneApplicationPage phoneApplicationPage;
    public IsolatedStorageSettings appsettings;


    //public Timer(PhoneApplicationPage callingPhoneApplicationPage)
    //{
    //    this.phoneApplicationPage = callingPhoneApplicationPage;
    //}

    public void startTimer(PhoneApplicationPage callingPhoneApplicationPage, int noOfSeconds, IsolatedStorageSettings calledAppsettings)
    {
        this.appsettings = calledAppsettings;
        this.phoneApplicationPage = callingPhoneApplicationPage;
        dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
        dispatcherTimer.Tick += new EventHandler(timer_time_done);
        dispatcherTimer.Interval = new TimeSpan(0, 0, noOfSeconds);
        dispatcherTimer.Start();
    }
    public void timer_time_done(object sender, EventArgs e)
    {
        dispatcherTimer.Stop();
        BsgFunctions.logout_Forcefully_code(phoneApplicationPage, this, appsettings);
    }

    public void restartTimer(int noOfSeconds)
    {
        dispatcherTimer.Stop();
        startTimer(phoneApplicationPage, noOfSeconds,appsettings);
    }

    public void stopTimer()
    {
        dispatcherTimer.Stop();
    }

}
