Question

我想将我的单语言项目改为多语言，所以我使用ResourceDictionary这样做：

XAML

    <Button Content="{DynamicResource LanguageSetting}" Click="btn_LanguageSetting_Click"/>

代码背后

    public static string windowCurrentLanguageFile = "Language/en.xaml";
    private void btn_LanguageSetting_Click(object sender, RoutedEventArgs e)
    {
        windowCurrentLanguageFile = windowCurrentLanguageFile == "Language/en.xaml"
            ? "Language/ch.xaml"
            : "Language/en.xaml";

        var rd = new ResourceDictionary() { Source = new Uri(windowCurrentLanguageFile, UriKind.RelativeOrAbsolute) };

        if (this.Resources.MergedDictionaries.Count == 0)
            this.Resources.MergedDictionaries.Add(rd);
        else
            this.Resources.MergedDictionaries[0] = rd;
    }

这对我来说很好。但我有ItemsControl

<ItemsControl ItemsSource="{Binding ItemOperate}">
        <ItemsControl.ItemTemplate>
            <DataTemplate DataType="{x:Type viewmodel:SelectableViewModel}">
                <Border x:Name="Border" Padding="0,8,0,8" BorderThickness="0 0 0 1" BorderBrush="{DynamicResource MaterialDesignDivider}">
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition SharedSizeGroup="Checkerz" />
                            <ColumnDefinition />
                        </Grid.ColumnDefinitions>
                        <ToggleButton VerticalAlignment="Center" IsChecked="{Binding IsSelected}"
                                      Style="{StaticResource MaterialDesignActionLightToggleButton}"
                                      Content="{Binding Code}" />
                        <StackPanel Margin="8 0 0 0" Grid.Column="7">
                            <TextBlock FontWeight="Bold" Text="{Binding Name}" />
                            <TextBlock Text="{Binding Description}" />
                        </StackPanel>
                    </Grid>
                </Border>
                <DataTemplate.Triggers>
                    <DataTrigger Binding="{Binding IsSelected}" Value="True">
                        <Setter TargetName="Border" Property="Background" Value="{DynamicResource MaterialDesignSelection}" />
                    </DataTrigger>
                </DataTemplate.Triggers>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>

哪个绑定到 ViewModel ，如下所示：

public class SelectableViewModel : INotifyPropertyChanged
{ 
    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName = null)
    {
        var handler = PropertyChanged;
        if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));
    }

    private bool _isSelected;
    public bool IsSelected
    {
        get { return _isSelected; }
        set
        {
            if (_isSelected == value) return;
            _isSelected = value;
            OnPropertyChanged();
        }
    }

    private char _code;
    public char Code
    {
        get { return _code; }
        set
        {
            if (_code == value) return;
            _code = value;
            OnPropertyChanged();
        }
    }

    private string _name;
    public string Name
    {
        get { return _name; }
        set
        {
            if (_name == value) return;
            _name = value;
            OnPropertyChanged();
        }
    }

    private string _description;
    public string Description
    {
        get { return _description; }
        set
        {
            if (_description == value) return;
            _description = value;
            OnPropertyChanged();
        }
    }
}

并且

    public MainViewModel()
    {
        _itemOperate = CreateData();
    }

    private static ObservableCollection<SelectableViewModel> CreateData()
    {
        return new ObservableCollection<SelectableViewModel>
            {
                new SelectableViewModel
                {
                    Code = 'E',
                    Name = "Erase",
                    Description = "Erase The MCU Chip By Page"
                },
                new SelectableViewModel
                {
                    Code = 'D',
                    Name = "Detect",
                    Description = "Detect The MCU Flash",
                },
                new SelectableViewModel
                {
                    Code = 'P',
                    Name = "Programming",
                    Description = "Programming The MCU Chip By Hex File",
                },
                new SelectableViewModel
                {
                    Code = 'V',
                    Name = "Verify",
                    Description = "Verify The Downing Code",
                },
                new SelectableViewModel
                {
                    Code ='L',
                    Name = "Lock",
                    Description = "Lock The Code To Protect The MCU",
                }
            };
    }

那么我应该如何将其改为多种语言？提前谢谢！

Answer 1

首先，我建议您更改本地化引擎。有很多不同的方式。有一个最简单的变体： https://www.codeproject.com/Articles/299436/WPF-Localization-for-Dummies

此外，此工具将帮助您管理资源文件： https://marketplace.visualstudio.com/items?itemName=TomEnglert.ResXManager

你问题的答案：如果要本地化模型，则应使用资源字典创建它，而不是使用硬编码字符串。如果你像上面提到的那样实现你的本地化引擎，这很容易制品

{
return new ObservableCollection<SelectableViewModel>
    {
        new SelectableViewModel
        {
            Code = 'E',
            Name = YourResourcesProject.Resources.Erase,
            Description = YourResourcesProject.Resources.EraseTheMCUChipByPage
        },
        new SelectableViewModel
        {
            Code = 'D',
            Name = YourResourcesProject.Resources.Detect,
            Description = YourResourcesProject.Resources.DetectTheMCUFlash
        },
        new SelectableViewModel
        {
            Code = 'P',
            Name = YourResourcesProject.Resources.Programming,
            Description = YourResourcesProject.Resources.ProgrammingTheMCUChipByHexFile
        },
        new SelectableViewModel
        {
            Code = 'V',
            Name = YourResourcesProject.Resources.Verify,
            Description = YourResourcesProject.Resources.VerifyTheDowningCode
        },
        new SelectableViewModel
        {
            Code ='L',
            Name = YourResourcesProject.Resources.Lock,
            Description = YourResourcesProject.Resources.LockTheCodeToProtectTheMCU
        }
    };

}

Answer 2

不要改变任何事情......将您的SelectableViewModel集合转换为XML并更改CreateData以将其加载到本地化版本中 - 您可以为每种语言提供文件或将所有语言混合在一起

Answer 3

20行代码....如你所愿 - 不能比那更明确： - （

   public class Selectable(View)Model
    {

    [XmlAttribute]
    public string Code { get; set; }

    [XmlAttribute]
    public string Name { get; set; }

    [XmlAttribute]
    public string Description { get; set; }
}

///you can deserialize your view model directly
private ObservableCollection<SelectableViewModel> CreateData()
{
   return new ObservableCollection<SelectableViewModel>( Deserialize( file_name_code_lang.xml, SelectableViewModel) );
}

//    or going through a model class
private ObservableCollection<SelectableViewModel> CreateData()
    {
       return new ObservableCollection<SelectableViewModel>( Deserialize( file_name_code_lang.xml, SelectableModel ).Foreach(p=> new SelectableViewModel(p) );
    }

static public object Deserialize(string filePath, Type objType)
    {
        object objToDeserialize = null;

        XmlTextReader xmlReader = null;
        XmlSerializer xmls = null;

        try
        {
            xmlReader = new XmlTextReader(filePath);
            xmls = new XmlSerializer(objType);

            objToDeserialize = xmls.Deserialize(xmlReader);
        }
        catch (Exception err)
        {
            BusinessLogger.Manage(err);
            return null;
        }
        finally
        {
            xmls = null;
            xmlReader.Close();
        }

        return objToDeserialize;
    }
