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}"
答案 2 :(得分:8)
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:
xmlns:resource="clr-namespace:YourProject.Properties"
在ApplicationResources(app.xaml文件)中为* .resx文件添加资源
<Application.Resources>
<resource:ResourceFileName x:Key="ApplicationStringResources" />
</Application.Resources>
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
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
#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.
/// </summary>
/// <param name="binder">Provides information about the object that called the dynamic operation. The binder.Name property provides the name of the member on which the dynamic operation is performed. For example, for the Console.WriteLine(sampleObject.SampleProperty) statement, where sampleObject is an instance of the class derived from the <see cref="T:System.Dynamic.DynamicObject"/> class, binder.Name returns "SampleProperty". The binder.IgnoreCase property specifies whether the member name is case-sensitive.</param>
/// <param name="result">The result of the get operation. For example, if the method is called for a property, you can assign the property value to <paramref name="result"/>.</param>
/// <returns>
/// true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a run-time exception is thrown.)
/// </returns>
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>
/// Initializes a new instance of the <see cref="ResourceLoader"/> class.
/// </summary>
public ResourceLoader()
: this(CultureInfo.InvariantCulture, DefaultResourcesSuffix)
{ }
/// <summary>
/// Initializes a new instance of the <see cref="ResourceLoader"/> class.
/// </summary>
public ResourceLoader(CultureInfo InitCulture, string ResourceSuffix)
{
_defaultAssemblyName = GetType().Assembly.GetName().Name;
_defaultAssembly = GetType().Assembly;
this.culture = InitCulture;
this.resourcesSuffix = ResourceSuffix;
}
#endregion // Constructors
}
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="" />
