WPF中区域性更改后更新资源字符串(GUI中的文本)

本文关键字：GUI 文本 字符串 更新 区域性 WPF 资源 | 更新日期: 2023-09-27 18:10:44

我正在研究WPF应用程序的本地化。我的问题是，当我从组合框(下拉)更改语言时，我想更新整个应用程序的文本。但我不知道该怎么做。

我使用。resx文件作为我的资源文件。

。如果选择的语言是英语，那么文本将是英语，但当我将其更改为法语时，我想从法语资源文件更新按钮的文本。

提供优质商品的建议也可以接受。我正在寻找大型应用程序的良好解决方案。

WPF中区域性更改后更新资源字符串(GUI中的文本)

从我看到的所有解决方案中，最好的是使用字典与字符串，绑定到动态资源，和字符串管理器

}

和

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:s="clr-namespace:System;assembly=mscorlib"
xmlns:w="clr-namespace:System.Windows;assembly=PresentationCore">
<!-- Font size on map station labels -->
<s:Double x:Key="StationFontSize">12</s:Double>
<!-- FlowDirection LeftToRight ou RightToLeft -->
<w:FlowDirection x:Key="FlowDirection">LeftToRight</w:FlowDirection>
<!-- Dialog -->
<s:String x:Key="String.Dialog.OK">OK</s:String>
<s:String x:Key="String.Dialog.Cancel">Cancel</s:String>
<s:String x:Key="String.Dialog.Yes">Yes</s:String>
<s:String x:Key="String.Dialog.No">No</s:String>

或者你有另一种解决方案但是更复杂cbr
