我正在为我的学期项目创建一个应用程序。在这个项目中，我有一个简单的类文件和一些xaml页面。在一个xaml页面中，代码检查字符串的值，并根据该值运行倒计时器。如果string的值等于某个字符串，那么它应该从简单的类中调用一个方法，其中string的值被更改，然后它应该导航到下一个xaml页面。
当我调用该函数时，应用程序会中断。没有错误或任何东西，它只是打破。我不知道为什么。我在其他xaml文件中调用了同一类文件的其他函数，它们工作正常，但在这里我遇到了麻烦。我想这与计时器有关。
xaml.cs：
namespace TrafficGuru
{
public partial class Page2 : PhoneApplicationPage
{
DispatcherTimer countDownTimer;
int check;
public Page2()
{
InitializeComponent();
tbl.Text = global.str;
if (global.str == "YOUR LIGHT IS ON FOR : ")
{
check = 0;
}
if (global.str == "YOUR LIGHT WILL BE ON IN:")
{
check = 1;
}
if (global.str == "YOUR LIGHT WILL NOT BE ON FOR UNTIL ATLEAST " + global.x * 15 + " MORE SECS.YOU WILL GET AN UPDATE IN:")
{
check = 2;
}
countDownTimer = new DispatcherTimer();
countDownTimer.Interval = new TimeSpan(0, 0, 0, 1);
countDownTimer.Tick += new EventHandler(countDownTimerEvent);
countDownTimer.Start();
test.Content = "" + "seconds remaining";
}
int count = global.cdt;
void test_Click(object sender, EventArgs e) { }
void countDownTimerEvent(object sender, EventArgs e)
{
test.Content = count + " Seconds";
if (count > 0)
{
count--;
}
else if (count == 0)
{
if (check == 0)
{
test.Content = "STOP!!";
}
else if (check == 1)
{
test.Content = "GO!!!";
}
if(check==2)
{
string x= global.rego();//the method i m trying to call its public and static
NavigationService.Navigate(new Uri("/Page3.xaml", UriKind.RelativeOrAbsolute));*/
}
}
}
}
}
