问题合并的ResourceDictionary在WPF

Question

public partial class App : Application 
    { 
     public App() 
     { 
      switch (Thread.CurrentThread.CurrentCulture.ToString()) 
      { 
       case "de-DE": 
        var German = new Uri("..\\GlobalString\\Dictionary_de-DE.xaml", UriKind.RelativeOrAbsolute); 
        Application.Current.Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = German }); 
        break; 
       case "it-IT": 
        var Italy = new Uri("..\\GlobalString\\Dictionary_it-IT.xaml", UriKind.RelativeOrAbsolute); 
        Application.Current.Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = Italy }); 
        break; 
       case "es-ES": 
        var Spanish = new Uri("..\\GlobalString\\Dictionary_es-ES.xaml", UriKind.RelativeOrAbsolute); 
        Application.Current.Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = Spanish }); 
        break; 
       case "fr-FR": 
        var France = new Uri("..\\GlobalString\\Dictionary_fr-FR.xaml", UriKind.RelativeOrAbsolute); 
        Application.Current.Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = France }); 
        break; 
       default: 
        var English = new Uri("..\\GlobalString\\Dictionary_de-DE.xaml", UriKind.RelativeOrAbsolute); 
        Application.Current.Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = English }); 
        break; 
      } 
     } 
    } 

首先，我合并了所有的字典，然后我试图动态地得到解释像below.But它显示错误（“MyString的”资源未找到）的值。

private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     string StringFromDictionary= Application.Current.FindResource("MyString"); 
    } 

Answer 1

英文显示de-DE。你是复制粘贴的受害者吗？

不知道为WPF，但在Silverlight Application.Current.Resources [ “MyString的”]的作品。

在这旁边，你加入到Application.Resources.MergedDictionaries所以Application.Resources.MergedDictionaries [“我的字符串”]也可以为你工作。

也许FindResource只是看Application.Current.Resources？

• 我怀疑Application.Current是App的构造可用作Application.Current应该最终被App本身。尝试使用this.Resources.MergedDictionaries.Add代替。
• 您的“App.xaml”中是否有任何内容？如果是这样，它将取代App.Resources，并且您在构造函数中设置的所有内容都将丢失。
