Question

之間有條件檢查複選框，我目前在我的settings.xaml頁面下有一個複選框，用戶要點擊它來允許定位服務。

private void cbLocationAllow_Checked(object sender, RoutedEventArgs e) 
{ 
    MessageBox.Show("Location Services is now enabled"); 
} 

private void cbLocationAllow_Unchecked(object sender, RoutedEventArgs e) 
{ 
    MessageBox.Show("Location Services is now disabled"); 
} 

我對我的MainPage，我想有找到位置之前檢查settings.xaml複選框的狀態位置感知兵地圖。

我認爲這將是一個條件，否則，但我不太清楚如何實現這個複選框是在另一個頁面上。

下面的代碼有人建議我，但我對

Settings.SetSetting("allowLocation",true); 

讓錯誤在設置頁面：

cbLocationAllowChecked(...) 
{ 
Settings.SetSetting("allowLocation",true); 
} 

cbLocationAllowUnchecked(...) 
{ 
Settings.SetSetting("allowLocation,false); 
} 

在主要頁面條件

MapButtonClicked(...) 
{ 
if (!Settings.HasSetting("allowLocation") || !((bool)Settings.GetSetting("allowLocation")) 
     MessageBox.Show("Allow app to use your location?, "Location Services",MessageBoxButtons.OkCancel); 
//handle result 
else{ 

StartLocationSearch(); 
} 

} 

任何建議或者能夠幫助我的鏈接會很棒。

感謝，

使用IsolatedStorageSettings類保存設置。

保存設置

private void cbLocationAllow_Checked(object sender, RoutedEventArgs e) 
{ 
    var settings = IsolatedStorageSettings.ApplicationSettings; 

    settings["allowLocation"] = true; 
    settings.Save(); 
} 

要閱讀設置

var settings = IsolatedStorageSettings.ApplicationSettings; 
bool allowLocation = false; 

if(settings.Contains("allowLocation")) { 
    allowLocation = (bool)settings["allowLocation"]; 
}
