从XAML中的* .resx文件中获取值

标签: c# xaml localization resx

是否可以将资源文件中的某些值添加到XAML标记中?或者对于本地化,我们总是必须在* .cs文件中创建类似的东西:

txtMessage.Text = Messages.WarningUserMessage;

Messages是资源,txtMessage是TextBlock。

确保在resx编辑器中将Code Generation设置为Public,然后您只需使用:

<TextBlock Text="{x:Static Messages.WarningUserMessage}" />

这样做要容易得多。在XAML文件中添加xmlns并直接使用资源。

xmlns:resx="clr-namespace:wpfapplicationname.Properties"
Title="{x:Static resx:Resources.name}"

我理解我的回复有点迟了,但我认为值得分享:

使用存储在* .resx文件中的字符串而不使用Static关键字:

  1. 在App.Xaml文件中为Properties添加命名空间 xmlns:resource="clr-namespace:YourProject.Properties"
  2. 在ApplicationResources(app.xaml文件)中为* .resx文件添加资源

    <Application.Resources> <resource:ResourceFileName x:Key="ApplicationStringResources" /> </Application.Resources>

  3. 在您的XAML文件中使用以下Binding,让我们举一个Window Title的例子

    Title="{Binding TitleString, Source={StaticResource ResourceKey=ApplicationStringResources}}"

    TitleString是* .resx文件中的StringProperty名称

  4. 最后但并非最不重要的是,不要忘记将资源文件访问修饰符更改为Public。

最简单的方法可能是直接引用项目(它们是静态属性,默认为内部):

<TextBlock x:Name="txtMessage" Text="{x:Static MyApp.Properties.Resource.TextString}"/>

如果您正在使用本地化的WPF应用程序,那么我建议您在http://wpflocalization.codeplex.com/查看有关CodePlex的指南,如果您正在构建复合应用程序(使用PRISM或MEF),那么我有一个blog post on a nice way to accomplish WPF localisation using standard bindings

经过一整天的调查后,这篇评论Xaml localization: Using .resx Resources in Xaml without x:static我找到了一个简单的解决方案来提供多语言支持(嵌入式资源或引用程序集)* .resx - 文件。 从Framework 4开始,有一个名为DynamicObject的基类,用于在命名空间System.Dynamic中指定运行时的动态行为。

我从System.Dynamic.DynamicObject派生了以下ResourceLoader - class:

public class ResourceLoader : DynamicObject
{
    #region Fields ---------------------------------------------------------------

    private const string DefaultResourcesSuffix = "Resource";
    private ResourceManager _resourceMan;
    private CultureInfo culture;
    private readonly string _defaultAssemblyName;
    private readonly Assembly _defaultAssembly;
    private Assembly theAssembly;
    private string resourcesSuffix;
    private string assembly;

    #endregion // Fields

    /// <summary>

    /// </summary>
    public string Assembly
    {
        get { return assembly; }
        set
        {
            assembly = value;
            theAssembly = System.Reflection.Assembly.Load(assembly);
            _resourceMan = null;
        }
    }

    /// <summary>
    /// Gets or sets the resources suffix.
    /// </summary>
    public string ResourcesSuffix
    {
        get { return resourcesSuffix; }
        set
        {
            resourcesSuffix = value;
            _resourceMan = null;
        }
    }

    /// <summary>
    /// Get, set culture
    /// </summary>
    public CultureInfo CurrentCulture
    {
        get { this.culture = this.culture ?? CultureInfo.InvariantCulture; return this.culture; }
        set { this.culture = value; }
    }

    /// <summary>
    /// Creates new instace of <see cref="System.Resources.ResourceManager"/> at initialisation or change of <see cref="ResourceFileAccessSample.ResourceBinding.ResourceLoader.Assembly"/>.
    /// </summary>
    private ResourceManager ResourceManager
    {
        get
        {
            if (ReferenceEquals(_resourceMan, null))
            {
                ResourceManager temp = new ResourceManager(
                    string.Format("{0}.{1}", Assembly ?? _defaultAssemblyName, ResourcesSuffix ?? DefaultResourcesSuffix),
                    theAssembly ?? _defaultAssembly);
                _resourceMan = temp;
            }
            return _resourceMan;
        }
    }

    #endregion // Properties

    #region Methods --------------------------------------------------------------

    private object GetResource(string name, CultureInfo language)
    {
        if (language == null || language == CultureInfo.InvariantCulture)
            return ResourceManager.GetObject(name);
        return ResourceManager.GetObject(name, language);
    }

    /// <summary>

    {
        result = GetResource(binder.Name, this.culture);

        if (result != null && result.GetType() == typeof(System.Drawing.Bitmap))
        {
            System.Drawing.Bitmap currentBmp = result as System.Drawing.Bitmap;
            currentBmp.MakeTransparent(System.Drawing.Color.Magenta);
            BitmapSource src = Imaging.CreateBitmapSourceFromHBitmap(currentBmp.GetHbitmap(), IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
            result = src;
        }
        return result == null ? false : true;
    }

    /// <summary>
    /// Switch set culture

    public void SwitchCulture(CultureInfo NewCulture)
    {
        this.culture = NewCulture;

    { }

    /// <summary>

    public ResourceLoader(CultureInfo InitCulture, string ResourceSuffix)
    {
        _defaultAssemblyName = GetType().Assembly.GetName().Name;

        this.culture = InitCulture;
        this.resourcesSuffix = ResourceSuffix;
    }

您可以在xaml中创建实例,如下所示:

<Application x:Class="ResourceFileAccessSample.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"           
         xmlns:src="clr-namespace:ResourceFileAccessSample.ResourceBinding"             
         StartupUri="Window1.xaml" Startup="Application_Startup" >

<Application.Resources>
    <src:ResourceLoader x:Key="resource" CurrentCulture="(Default)" ResourcesSuffix="Resource"   />
</Application.Resources>

C#代码:

    /// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
    private ResourceLoader res;
    public Window1()
    {            
        InitializeComponent();
        // load it from WPF Resources 
        this.res = (ResourceLoader)this.FindResource("resource");
        // or create an instance 
        //this.res = new ResourceLoader(CultureInfo.InvariantCulture, "Resource");      
        this.LayoutRoot.DataContext = res;                    
    }

    private void btnSwichLanguage_Click(object sender, RoutedEventArgs e)
    {            
        res.SwitchCulture(new CultureInfo("de"));               
        this.LayoutRoot.DataContext = null;
        this.LayoutRoot.DataContext = res;                      
    }       
}

现在可以绑定字符串和图像(图像将转换为WPF编译器BitmapSource:

    <StackPanel Name="LayoutRoot" Orientation="Vertical">
    <Label Name="lblText" Content="{Binding Path=rsName, Mode=OneWay}" HorizontalContentAlignment="Center" Margin="5" Padding="0" />
    <Image Source="{Binding Path=AlignObjectsTop}" Height="16" Width="16" Margin="5" />
    <Button Name="btnSwichLanguage" Content="Switch to de" Click="btnSwichLanguage_Click" MinHeight="25" Width="100" />

</StackPanel>

最简单的方法,您可以根据每种语言的文本长度定义文本框的宽度。

Xaml Code

<TextBlock x:Uid="Greeting" Text="" />

Have a look at resource file:- Click View
