Xamarin在代码隐藏中形成本地化

code-behind multilingual localization xamarin.forms c#

here 并遵循指示。它仅适用于具有

<Label Text="{i18n:Translate SelectLanguage}"  />

但我需要它在我的代码背后:

 Label selectLabel = new Label
        {
            Text = "{i18n:Translate SelectLanguage}",
            TextColor = Color.Black
        };

该标签的输出为:{i18n:Translate-SelectLanguage}。

更新:

我的xaml页面:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         x:Class="MyProj.Forms.Pages.TestPages.ChangeLanguagePage"
         xmlns:i18n="clr-namespace:MyProj.Forms.Helpers"
         Title="{i18n:Translate ChangeLanguage}">>
<ContentPage.Content>
    <StackLayout Padding="20" VerticalOptions="CenterAndExpand">
        <Label   Text="{i18n:Translate SelectLanguage}"  />
        <Picker x:Name="picker" />
        <Button Text="{i18n:Translate Save}" Clicked="OnUpdateLangugeClicked" BackgroundColor="Black" TextColor="White"/>
    </StackLayout>
</ContentPage.Content>
</ContentPage>

我的代码隐藏页:

    [XamlCompilation(XamlCompilationOptions.Compile)]
public partial class ChangeLanguagePage : ContentPage
{
    Picker picker;
    public ChangeLanguagePage()
    {
        InitializeComponent();
        StackLayout main = new StackLayout();

        Label selectLabel = new Label
        {
            //Text = "Select Language",
            Text = "{i18n:Translate SelectLanguage}",
            TextColor = Color.Black
        };

        picker = new Picker();

        Button btn = new Button
        {
            Text = "SAVE",
            TextColor = Color.White,
            BackgroundColor = Color.Black
        };
        btn.Clicked += Btn_Clicked;
        picker.Items.Add("English");
        picker.Items.Add("Spanish");
        picker.Items.Add("Portuguese");
        picker.Items.Add("French");
        picker.SelectedItem = CrossMultilingual.Current.CurrentCultureInfo.EnglishName;

        main.Children.Add(selectLabel);
        main.Children.Add(picker);
        main.Children.Add(btn);

        Content = main;
    }

    private void Btn_Clicked(object sender, EventArgs e)
    {
        CrossMultilingual.Current.CurrentCultureInfo = CrossMultilingual.Current.NeutralCultureInfoList.ToList().First(element => element.EnglishName.Contains(picker.SelectedItem.ToString()));
        AppResources.Culture = CrossMultilingual.Current.CurrentCultureInfo;
        App.Current.MainPage = new NavigationPage(new HomePage());
    }

    void OnUpdateLangugeClicked(object sender, System.EventArgs e)
    {

        CrossMultilingual.Current.CurrentCultureInfo = CrossMultilingual.Current.NeutralCultureInfoList.ToList().First(element => element.EnglishName.Contains(picker.SelectedItem.ToString()));
        AppResources.Culture = CrossMultilingual.Current.CurrentCultureInfo;
        App.Current.MainPage = new NavigationPage(new HomePage());

    }
}

没有等效的代码,这些服务只能通过XAML提供

但是你可以很容易地替换它。

const string ResourceId = "$rootnamespace$.AppResources";
var resmgr = new ResourceManager(ResourceId,typeof(TranslateExtension).GetTypeInfo().Assembly));        
var ci = CrossMultilingual.Current.CurrentCultureInfo;
Label selectLabel = new Label
{
  Text = resmgr.GetString("SelectLanguage",ci),
  TextColor = Color.Black
};

$rootnamespace$ 使用项目命名空间。

Text = Resx.LocalizedString.SelectLanguage,

我很惊讶其他人说你说的很好,应该有效。

我不知道。无论如何,当你在代码中使用它时,你可以这样使用它。
