我想ProximityDevice
在我的应用程序中使用。如果我将其声明为字段或在构造函数中,如下所示:
public partial class MainPage : PhoneApplicationPage {
// Constructor
public ProximityDevice device;
public MainPage() {
InitializeComponent();
device = ProximityDevice.GetDefault();
}
}
或这个:
public partial class MainPage : PhoneApplicationPage {
// Constructor
public MainPage() {
InitializeComponent();
public ProximityDevice device = ProximityDevice.GetDefault();
}
}
我明白了
A first chance exception of type 'System.UnauthorizedAccessException' occurred in SecurityClient.DLL
A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.ni.dll
A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in Microsoft.Phone.ni.dll
如果我将其声明为静态代码不会导致任何问题:
public partial class MainPage : PhoneApplicationPage {
// Constructor
public static ProximityDevice device = ProximityDevice.GetDefault();
public MainPage() {
InitializeComponent();
}
}
如何解决这个问题?
