WPF 中的多语言[关闭]

您能推荐一种为 WPF 应用程序实现多语言系统的好方法吗？我现在使用的方法涉及 XML、类和 xaml 扩展。它在大多数情况下工作得很好，但是当我必须处理动态标签或动态文本时，它需要一些额外的努力。我想让程序员只处理主要问题，而忘记语言问题。

按着这些次序：

1)全部放置String片段在单独的资源文件中。

例子：StringResources.xaml:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:system="clr-namespace:System;assembly=mscorlib">

    <!-- String resource that can be localized -->
    <system:String x:Key="All_Vehicles">All Vehicles</system:String>

</ResourceDictionary>

2)为每种语言制作副本并将其添加（翻译）到合并的词典中。不要忘记添加该国家/地区的 ISO 代码以使事情变得更容易。

Example App.xaml:

<Application x:Class="WpfStringTables.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="Window1.xaml">
    <Application.Resources>
        <ResourceDictionary >
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="StringResources.de-DE.xaml" />
                <ResourceDictionary Source="StringResources.nl-NL.xaml" />
                <ResourceDictionary Source="StringResources.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

最后一个带有字符串的资源文件将用于替换代码中的文本部分。

3a)使用来自的文本部分String table:

Example Window1.xaml:

<Window x:Class="WpfStringTables.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
    <Grid>
        <Button Margin="51,82,108,129" Name="AllVehiclesButton" 
                Content="{StaticResource All_Vehicles}"/>
    </Grid>
</Window>

3b)从代码加载资源（仅当您不想通过设置时才使用此代码XAML):

void PageLoad()
{
  string str = FindResource("All_Vehicles").ToString();
}

4)在应用程序开始时切换到新的文化：

代码片段来自App.xaml.cs:

public static void SelectCulture(string culture)    
{      
    if (String.IsNullOrEmpty(culture))
        return;

    //Copy all MergedDictionarys into a auxiliar list.
    var dictionaryList = Application.Current.Resources.MergedDictionaries.ToList();

    //Search for the specified culture.     
    string requestedCulture = string.Format("StringResources.{0}.xaml", culture);
    var resourceDictionary = dictionaryList.
        FirstOrDefault(d => d.Source.OriginalString == requestedCulture);

    if (resourceDictionary == null)
    {
        //If not found, select our default language.             
        requestedCulture = "StringResources.xaml";
        resourceDictionary = dictionaryList.
            FirstOrDefault(d => d.Source.OriginalString == requestedCulture);
    }

    //If we have the requested resource, remove it from the list and place at the end.     
    //Then this language will be our string table to use.      
    if (resourceDictionary != null)
    {
        Application.Current.Resources.MergedDictionaries.Remove(resourceDictionary);
        Application.Current.Resources.MergedDictionaries.Add(resourceDictionary);
    }

    //Inform the threads of the new culture.     
    Thread.CurrentThread.CurrentCulture = new CultureInfo(culture);
    Thread.CurrentThread.CurrentUICulture = new CultureInfo(culture);

}
