我在我的应用程序中使用多种语言 我试图用MVVM模式做这个，这对我来说是新的，所以 我从CodeProject和Tutorialspoint阅读了教程。
继承我的项目结构：
Model
ConverterModel.cs
LanguageModel.cs
ViewModel
ConverterViewModel.cs
View
ConverterView.xaml
ConverterView.xaml.cs
MainWindow.xaml
MainWindow.xaml.cs
我为我需要的所有语言字符串创建了一个模型：
internal class LanguageModel : INotifyPropertyChanged
{
//GUI Language
private string title;
private string inputBtn;
private string outputBtn;
private string convertBtn;
...
public string Title
{
get
{
return title;
}
set
{
if(title != value)
{
title = value;
RaisePropertyChanged("Title");
}
}
}
public string InputBtn
{
get
{
return inputBtn;
}
set
{
if (inputBtn != value)
{
inputBtn = value;
RaisePropertyChanged("InputBtn");
}
}
}
public string OutputBtn
{
get
{
return outputBtn;
}
set
{
if (outputBtn != value)
{
outputBtn = value;
RaisePropertyChanged("OutputBtn");
}
}
}
public string ConvertBtn
{
get
{
return convertBtn;
}
set
{
if (convertBtn != value)
{
convertBtn = value;
RaisePropertyChanged("ConvertBtn");
}
}
}
...
public event PropertyChangedEventHandler PropertyChanged;
private void RaisePropertyChanged(string property)
{
if(PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}
}
}
然后我在我的ViewModel中创建该模型的一个实例，并用所需的数据填充它：
internal class ConverterViewModel
{
internal Settings Settings{ get; set; }
ConverterModel Model { get; set; } //where the Data Fill Method is located
internal LanguageModel LanguageModel { get; set; }
String Title {get; set;} = "Banana"; //<-- this seems to work just fine
internal ConverterViewModel()
{
Model = new ConverterModel();
Settings = new Settings();
if(Settings.Language == "")
{
Settings.Language = "English";
//getLanguage
Settings.Save();
}
this.LanguageModel = Model.SetLanguageModel(Settings.Language);
}
ConverterModel中的数据填充方法：
class ConverterModel
{
internal LanguageModel SetLanguageModel(string language)
{
switch (language)
{
case "English":
LanguageModel english = new LanguageModel()
{
Title = "TitleSomething",
InputBtn = "Inputfile",
OutputBtn = "Outputfile",
ConvertBtn = "Convert",
};
return english;
case "German":
LanguageModel german = new LanguageModel()
{
//Work in Progress
};
return german;
case "French":
LanguageModel french = new LanguageModel()
{
//Work in Progress
};
return french;
case "Italian":
LanguageModel italian = new LanguageModel()
{
//Work in Progress
};
return italian;
default: return null;
}
}
}
我的Bindings设置如下。
MainWindow：

</Grid>
</Grid>
我不知道我是否未能设置我的Bindings来访问LanguageModel实例的属性
或者RaisePropertyChanged（）方法以错误的方式实现。
我之前尝试过像Path= LanguageModel.Property那样设置我的Bindings。
我试图将模型属性放在一个可观察的列表中并通过它进行迭代，这也没有用。
此外，当我尝试调试程序并将鼠标悬停在LangaugeModel属性上时，调试器会因StackOverFlow异常而关闭。 现在从Exception我猜我的程序被某个循环陷入某个地方，但我无法找到它。
我希望这个详细到足以理解我的问题。（第一篇文章）

请注意，存在在XAML标记中进行本地化的项目（例如wpflocalizeextension.codeplex.com）。你不必自己做。
