从XAML中的* .resx文件中获取值

Question

Is it possible to add some value from resource file right into the XAML markup? Or for localization we always have to make something like this in *.cs file:

txtMessage.Text = Messages.WarningUserMessage;

Where Messages is resource, and txtMessage is TextBlock.

Answer 1

确保在resx编辑器中将Code Generation设置为Public，然后您可以简单地使用：

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

Answer 2

It's a lot easier to do it like this. Add a xmlns in XAML file and use the resources directly.

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

Answer 3

I understand my reply is a bit late, but I thought its worth sharing:

To use a string stored in the *.resx file without Static keyword:

1. In App.Xaml file add a namespace for Properties xmlns:resource="clr-namespace:YourProject.Properties"

2. In ApplicationResources(app.xaml file) Add a Resource for your *.resx file

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

3. In your XAML file use the following Binding, let us take an example of Window Title

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

   TitleString is the name of StringProperty in your *.resx file

4. Last but not least, don't forget to change the resource file access modifier to Public.

Answer 4

The simplest way is probably to reference the items directly (they are static properties, internal by default):

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

If you are working on a localised WPF app though then I'd recommend taking a look at the guidance on CodePlex at http://wpflocalization.codeplex.com/ , and if you're building a composite app (using PRISM or MEF) then I have a blog post on a nice way to accomplish WPF localisation using standard bindings .

Answer 5

After a whole day investigation this Comment Xaml localization: Using .resx Resources in Xaml without x:static I found a simple solution to provide multilanguage support with (embedded resources or referenced assembly) *.resx - files. Since Framework 4 there is a base class called DynamicObject for specifying dynamic behavior at run time in namespace System.Dynamic.

I derived following ResourceLoader from System.Dynamic.DynamicObject - 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

    #region Properties -----------------------------------------------------------

    /// <summary>
    /// Gets or sets the assembly.
    /// </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>
    /// Provides the implementation for operations that get member values. Classes derived from the <see cref="T:System.Dynamic.DynamicObject"/> class can override this method to specify dynamic behavior for operations such as getting a value for a property.

    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        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
    /// </summary>
    public void SwitchCulture(CultureInfo NewCulture)
    {
        this.culture = NewCulture;
    }
    #endregion // Methods

    #region Constructors ---------------------------------------------------------

    /// <summary>

    public ResourceLoader(CultureInfo InitCulture, string ResourceSuffix)
    {
        _defaultAssemblyName = GetType().Assembly.GetName().Name;
        _defaultAssembly = GetType().Assembly;
        this.culture = InitCulture;
        this.resourcesSuffix = ResourceSuffix;
    }

You can create instance within xaml like this:

<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# code:

    /// <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;                      
    }       
}

Now it is possible to bind strings and images (images will be converted into WPF compilant 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>

Answer 6

The simplest way, where you can define the width of textbox also according to the length of text in each language.

Xaml Code

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

Have a look at resource file:- Click View

Answer 7

隐藏其他文本块并绑定它的文本在该文本块中，您将拥有来自.cs的资源
