的NavigationService Windows Phone中的Silverlight

Question

我可以調用的NavigationService與Btn_Click方法

private void Com_Click(object sender, RoutedEventArgs e) 
{ string test = "Com"; 
    var x = NavigationService.Navigate(new Uri(@"/PageList.xaml" + "?msg1=" + test, UriKind.Relative)); 
} 

但我不能調用同一服務在這條路上

public MainPage() 
{ 
    InitializeComponent(); 
    ... 
    Test(); 
}  
private void Test() 
{ string test = "Com"; 
    var x = NavigationService.Navigate(new Uri(@"/PageList.xaml" + "?msg1=" + test, UriKind.Relative)); 
} 

Answer 1

嘗試沒有var x =：

private void Test() 
    { 
    string test = "Com"; 
    NavigationService.Navigate(new Uri(@"/PageList.xaml" + "?msg1=" + test, UriKind.Relative)); 
    }
