Question

我的网站有三个域.com，.de和.it

每个域都需要默认为该国家/地区的当地语言/文化。我创建了一个基页并添加了一个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。

所以在我的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会覆盖所做的任何按钮选择。有没有什么方法可以让InitialCulture检查是否发生了按钮点击，如果是，则跳过例程？

非常感谢任何建议，谢谢。

Answer 1

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

Answer 2

我的解决方案是将其分为两部分：

在会话开始时，我会存储文化派生自会话中的域变量
在InitializeCulture中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。

Answer 3

如果用户选择了该语言，您只需重定向到相应的域即可？如果用户将他的语言切换为“意大利语”，则可以将Response.Redirect转到“www.domain.it”。之后，您的“InitializeCulture”方法将非常谨慎。

ASP.NET使用InitializeCulture设置文化
