【中文标题】单击按钮时更改文化（语言）

【英文标题】：changing culture(language) when button click

【问题描述】：

我有一个使用框架 4 的网站。我使用全球资源进行了语言更改。在按钮点击代码后面我使用这些代码。

 protected void Button2_Click(object sender, EventArgs e)

    dil = "en-US";
    var ci = new CultureInfo(dil); //TO_DO Route culture 
    Thread.CurrentThread.CurrentUICulture = ci;
    Thread.CurrentThread.CurrentCulture = ci;
    Session["culture"] = ci;

还有我的 resx 文件：

-PB.resx

-PB.en-US.resx

-PB.ru-RU.resx

默认语言可以正常工作，但我怎样才能更改为英语和俄语？我的错误在哪里？

【参考方案1】：

首先您应该将语言数据存储在 cookie 中。要设置页面语言，请覆盖 InitializeCulture 方法。

 protected override void InitializeCulture()
    
        var currentLanguage= HttpContext.Current.Request.Cookies["dil"];
        string defaultLanguage="tr";
        if(currentLanguage==null)
        
        //set cookie to defaultLanguage
        
        else
        Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(currentLanguage.Value);
        Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;
        
    

点击按钮更改语言

protected void Button2_Click(object sender, EventArgs e)

    dil = "en-US";
    Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(dil);
    Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;
    HttpCookie hc = new HttpCookie("dil");
    hc.Expires=DateTime.Now.AddDays(30);
    hc.Value=dil;
    HttpContext.Current.Response.Cookies.Add(hc);

【讨论】：

如何在 cookie 中设置默认语言。我不知道使用cookie！

//将cookie设置为defaultLanguage HttpCookie hc = new HttpCookie("dil"); hc.Expires=DateTime.Now.AddDays(30); hc.Value="tr"; HttpContext.Current.Response.Cookies.Add(hc);

不幸的是我的 c# 不支持。我使用 c# 第 4 版 =(

我也想在母版页中制作这个。我不能使用 InitializeCulture()。它在页面中工作

您可以在 Global.asax 文件中使用 Application_BeginRequest 方法代替 InitializeCulture

【参考方案2】：

经过长时间的搜索，我解决了它。这是答案和您需要的所有代码。我为 Visual Studio 2010 中的母版页制作了这个。

您可以在页面加载中使用 ispostback。

protected void Page_Load(object sender, EventArgs e)


    //only does it on non-postback because otherwise the selected 
    //value will not reach event handler correctly 
    if (!Page.IsPostBack)
    
        dil = Thread.CurrentThread.CurrentCulture.Name;
    

之后我们可以添加按钮点击和cookies

 protected void Button2_Click(object sender, EventArgs e)



    dil = "en-US";
    //var ci = new CultureInfo(dil); //TO_DO Route culture 
    //Thread.CurrentThread.CurrentUICulture = ci;
    //Thread.CurrentThread.CurrentCulture = ci;
    //Session["culture"] = ci;

    //Sets the cookie that is to be used by Global.asax
    HttpCookie cookie = new HttpCookie("CultureInfo");
    cookie.Value = dil;
    Response.Cookies.Add(cookie);

    //Set the culture and reload the page for immediate effect. 
    //Future effects are handled by Global.asax
    Thread.CurrentThread.CurrentCulture =
                  new CultureInfo(dil);
    Thread.CurrentThread.CurrentUICulture =
                  new CultureInfo(dil);
    Server.Transfer(Request.Path);

最后一个 global.asax 文件有助于解决这个问题。

  //*
 Public void Application_BeginRequest(Object sender, EventArgs e) 
      
 // Code that runs on application startup                                                            
 HttpCookie cookie = HttpContext.Current.Request.Cookies["CultureInfo"];
 if (cookie != null && cookie.Value != null) 
 
 System.Threading.Thread.CurrentThread.CurrentUICulture = new  
 System.Globalization.CultureInfo(cookie.Value);
 System.Threading.Thread.CurrentThread.CurrentCulture = new     
 System.Globalization.CultureInfo(cookie.Value);
 
 else
 
 System.Threading.Thread.CurrentThread.CurrentUICulture = new   
 System.Globalization.CultureInfo("tr-TR");
 System.Threading.Thread.CurrentThread.CurrentCulture = new   
 System.Globalization.CultureInfo("tr-TR");
 
 
 //*

如果您使用的是 html 标签而不是 .net 标签，您可以使用这些标签来添加文本控件。

<a><asp:Literal ID="Literal1" runat="server" Text="<%$Resources: PB, Home %>"  /></a>
