我有一个单一的代码库,可以在各种配置下安装OOB SL5应用程序。根据运行时的配置(通过init参数选择),我想在执行安装之前更新OOB设置(标题,窗口标题)。看起来唯一的方法是通过OutOfBrowserSettings.xml文件(或项目设置UI)在编译时进行。我是否遗漏了什么,还是这就是现状?

添加了文件ResourceMock.cs:
public class ResourceMock:INotifyPropertyChanged
{
public string Title
{
get
{
MessageBox.Show(Thread.CurrentThread.CurrentCulture.Name);
switch (Thread.CurrentThread.CurrentCulture.Name)
{
case "en-GB": return "English"; break;
case "pl-PL": return "Polish"; break;
default: return "default";
break;
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
public void firePropertyChanged(string property)
{
OnPropertyChanged(property);
}
}
MainPage.xaml.cs:
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
if (App.IsRunningOOBWithPermission)
{
txtInfo.Text = "You are running outside Browser Window.";
}
else
{
txtInfo.Text = "You are running inside Browser Window.";
}
}
private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var cultrue = (e.AddedItems[0] as ComboBoxItem).Content.ToString();
try
{
Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(cultrue);
var res = App.Current.Resources["resxWrapper"] as ResourceMock;
res.firePropertyChanged("Title");
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
}

这是一个非常简单的示例,展示您可以在运行时更改标题。假设如果您将标题公开为可绑定属性,则知道如何实现自己的本地化。
要使上述示例正常工作,您需要在项目文件(*.csproj)中的SupportedCultrues标签中添加“en-GB;pl-PL”。
