XAML bind to static method with parameters
提问by Gerrit
I got a static class like the following:
我得到了一个如下所示的静态类：
public static class Lang
{
public static string GetString(string name)
{
//CODE
}
}
Now i want to access this static function within xaml as a binding. Is there such a way for example:
现在我想在 xaml 中访问这个静态函数作为绑定。有没有这样的方法，例如：
<Label Content="{Binding Path="{x:static lang:Lang.GetString, Parameters={parameter1}}"/>
Or is it necessary to create a ObjectDataProvider for each possible parameter?
或者是否有必要为每个可能的参数创建一个 ObjectDataProvider？
Hope someone is able to help me. Thanks in advance!
希望有人能够帮助我。提前致谢！

I get this need too. I "solved" using a converter (like suggested here).
我也有这个需求。我使用转换器“解决”了（就像这里建议的那样）。
First, create a converter which return the translated string:
首先，创建一个返回翻译后字符串的转换器：
public class LanguageConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
if (parameter == null)
return string.Empty;
if (parameter is string)
return Resources.ResourceManager.GetString((string)parameter);
else
return string.Empty;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
then use it into XAML:
然后将其用于 XAML：
<Window.Resources>
<local:LanguageConverter x:Key="LangConverter" />
</Window.Resources>
<Label Content="{Binding Converter={StaticResource LangConverter},
ConverterParameter=ResourceKey}"/>
Regards.
问候。

The right way would be to go the objectdataprovider route. Although if you are just binding to text rather than use a label, I would use a textblock.
正确的方法是走 objectdataprovider 路线。虽然如果您只是绑定到文本而不是使用标签，我会使用文本块。
<ObjectDataProvider x:Key="yourStaticData"
ObjectType="{x:Type lang:Lang}"
MethodName="GetString" >
<ObjectDataProvider.MethodParameters>
<s:String>Parameter1</s:String>
</ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
<TextBlock Text={Binding Source={StaticResource yourStaticData}}/>
