ASP.NET 使用 InitializeCulture 设置区域性

Question

我有一个包含三个域 .com、.de 和 .it 的网站。

每个域都需要默认为该国家/地区的本地语言/文化。 我创建了一个基本页面并添加了一个 InitializeCulture

  Protected Overrides Sub InitializeCulture()

    Dim url As System.Uri = Request.Url
    Dim hostname As String = url.Host.ToString()
    Dim SelectedLanguage As String

    If HttpContext.Current.Profile("PreferredCulture").ToString Is Nothing Then

        Select Case hostname
            Case "www.domain.de"
                SelectedLanguage = "de"

                Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage)
                Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage)

            Case "www.domain.it"
                SelectedLanguage = "it"

                Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage)
                Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage)

            Case Else
                SelectedLanguage = "en"

                Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage)
                Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage)
        End Select
    End If
End Sub

这很好。现在出现问题是因为我们还希望主页上有三个语言选择按钮，以便用户可以覆盖域语言。

因此，在我的 Default.asp.vb 上，我们有三个像这样的按钮事件...

Protected Sub langEnglish_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles langEnglish.Click

    Dim SelectedLanguage As String = "en"
    'Save selected user language in profile'
   HttpContext.Current.Profile.SetPropertyValue("PreferredCulture", SelectedLanguage)

    'Force re-initialization of the page to fire InitializeCulture()'
    Context.Server.Transfer(Context.Request.Path)


End Sub

但是当然，InititalizeCulture 然后会覆盖所做的任何按钮选择。有什么方法可以让 InitialCulture 检查是否发生了按钮单击，如果是则跳过例程？

任何建议将不胜感激，谢谢。

Protected Overrides Sub InitializeCulture()

    'Set the PreferredCulture as the SelectedLanguage by default'
    Dim SelectedLanguage As String = HttpContext.Current.Profile("PreferredCulture").ToString()

    'If there is no PreferredCulture, use these defaults'
    If [String].IsNullOrEmpty(SelectedLanguage) = True Then

        Select Case Request.Url.Host.ToString()
            Case "www.domain.de"
                SelectedLanguage = "de"

            Case "www.domain.it"
                SelectedLanguage = "it"

            Case Else
                SelectedLanguage = "en"

        End Select
    End If

    'Finally set the culture'
    Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage)
    Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage)
End Sub

我的解决方案是将其分为两部分：

1. 在会话开始时，我存储文化
   从会话中的域派生
   变量
2. 在 InitializeCulture 我采取
   会话变量的值
   初始化文化

要更改语言，我只需更改会话变量并重新初始化页面。

如果用户选择语言，您可以重定向到适当的域吗？如果用户将其语言切换为“意大利语”，您可以 Response.Redirect 他到“www.domain.it”。之后你的“InitializeCulture”方法就会起作用。
