Question

我第一次做国际化，我有一个问题：

我想知道是否可以从母版页进行国际化。我添加了一个带有一些语言的下拉列表，我正在使用一个会话，所以当我更改一种语言时，会检测到新文化并且它会发生变化，页面会被重新加载并且内容（我正在使用资源）被翻译。但它不起作用。

我在这里附上一些代码：

- Modules.master.vb -

    Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
    _Website = clsWebsiteDA.GetById(CInt(Request.QueryString("web")))
    If Not Session("cms_language") Is Nothing Then
        LanguageDropDownList1.SelectedValue = Session("cms_language")
        Dim sCulture As String = Session("cms_language")
        Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(sCulture)
        Thread.CurrentThread.CurrentUICulture = New CultureInfo(sCulture)
    End If
End Sub

    Protected Sub LanguageDropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles LanguageDropDownList1.SelectedIndexChanged
    Session("cms_language") = LanguageDropDownList1.SelectedValue
    Response.Redirect(Request.Url.ToString)
End Sub

结束班

- Modules.master（CSS） -

                    <asp:DropDownList ID="LanguageDropDownList1" runat="server" AutoPostBack="True" 
                            Height="16px" Width="65px" 
                            meta:resourcekey="LanguageDropDownList1Resource1">
                    <asp:ListItem Value="nl" meta:resourcekey="ListItemResource1">Dutch</asp:ListItem>
                    <asp:ListItem Value="fr" meta:resourcekey="ListItemResource1">French</asp:ListItem>
                    <asp:ListItem Value="es" meta:resourcekey="ListItemResource2">Spanish</asp:ListItem>
                    <asp:ListItem Value="en" meta:resourcekey="ListItemResource3">English</asp:ListItem>
                </asp:DropDownList>

如果不能这样做，那么正确的方法是什么？提前谢谢，

更新

我通过这个link找到了我认为符合我的问题的解决方案。但现在我有继承问题。我在文件夹中创建了一个名为Basepage.aspx的新WebForm：

Imports System.Globalization

导入System.Threading

部分类基页继承System.Web.UI.Page

Protected Overrides Sub InitializeCulture()
    If Request.Form("DropDownList1") IsNot Nothing Then
        Dim selectedLanguage As String = _
            Request.Form("DropDownList1")
        UICulture = Request.Form("DropDownList1")
        Culture = Request.Form("DropDownList1")
        Thread.CurrentThread.CurrentCulture = _
            CultureInfo.CreateSpecificCulture(selectedLanguage)
        Thread.CurrentThread.CurrentUICulture = New  _
            CultureInfo(selectedLanguage)
    End If
    MyBase.InitializeCulture()
End Sub

结束班

但是，当我在我的一个页面中删除时，

Partial Class Administration_index
Inherits System.Web.UI.Page

的

    Partial Class Administration_index
Inherits Basepage

它抱怨说它没有定义。我该如何处理这种继承？ VB赞赏，虽然C＃还可以......

是否必须尝试覆盖Page类的initializeCulture事件？

例如：

        /// <summary>
        /// Initializes culture for the page
        /// </summary>
        [VersionChange( "6.1.34.89", "24/12/2009", "Custom Cultures added" )]
        protected override void InitializeCulture()
        {
            try
            {
                CultureInfo oCultureInfo;

                try
                {
                    oCultureInfo = CultureInfo.CreateSpecificCulture( this.CurrentCustomCulture );
                }
                catch ( ArgumentException )
                {
                    //Get culture info based on Great Britain
                    CultureInfo cultureInfo = new CultureInfo( "en-GB" );
                    RegionInfo regionInfo = new RegionInfo( cultureInfo.Name );

                    CultureAndRegionInfoBuilder cultureAndRegionInfoBuilder = new CultureAndRegionInfoBuilder( this.CurrentCustomCulture, CultureAndRegionModifiers.None );

                    cultureAndRegionInfoBuilder.LoadDataFromCultureInfo( cultureInfo );
                    cultureAndRegionInfoBuilder.LoadDataFromRegionInfo( regionInfo );

                    // Custom Changes
                    cultureAndRegionInfoBuilder.CultureEnglishName = this.CurrentCustomCulture;
                    cultureAndRegionInfoBuilder.CultureNativeName = this.CurrentCustomCulture;

                    cultureAndRegionInfoBuilder.Register();

                    oCultureInfo = CultureInfo.GetCultureInfo( this.CurrentCustomCulture );
                }
                catch ( Exception )
                {
                    throw;
                }

                Thread.CurrentThread.CurrentCulture = oCultureInfo;
                Thread.CurrentThread.CurrentUICulture = oCultureInfo;

                Page.Culture = oCultureInfo.Name;
                Page.UICulture = oCultureInfo.Name;

                base.InitializeCulture();
            }
            catch ( Exception )
            {
                throw;
            }
        }

Answer 2

在其他地方询问并回答了类似问题（特别是有关本地化字符串资源的问题）：Localizing strings in master pages of ASP.NET MVC application

正如您所指出的，关键点是MasterPage不是Page的类型，因此它无法访问Page的资源机制。

如果您需要做的是在母版页中本地化字符串，并且如果可以在全局资源文件中找到本地化字符串，则此代码将在您的母版页的代码隐藏中起作用：

protected string GetLocalizedString(string key)
{
    return (string) GetGlobalResourceObject("default.aspx", key);
}

您可以在母版页本身中引用具有此类代码的本地化字符串：

<h1><%= GetLocalizedString("header_string_identifier") %></h1>

这完全取决于default.aspx.resx目录中的资源文件App_GlobalResources。虽然您显然知道如何创建资源文件，但为了完整性，我会说最简单的方法是调用Add，然后添加New Item，然后从Visual Studio的项目上下文菜单中调用Resource File。

虽然使用Visual Studio内置的资源编辑器创建资源条目很容易，但您也可以手动编辑它。无论哪种方式，资源文件都应包含这样的部分：

  <data name="header_string_identifier" xml:space="preserve">
    <value>This is the H1 text to display.</value>
  </data>

不容错过的两个细节是：

确保资源条目中的name=与密钥匹配母版页指令中的参数。
确保第一个 GetGlobalResourceObject调用中的参数与名称匹配删除了尾随.resx的资源文件。
