Question

我的下拉列表中有一个语言列表，其中包含en-NZ，en-US等形式的值，但页面不会更改回发语言，因为我的语言代码错误。有人可以查看我的代码并告诉我，我在改变我的页面语言时做错了吗

我的lbllanguage.Text会在第二次回发时发生变化，所以它假设在第一次点击时更改ChangeLanguage_Click事件

主页：

protected void Page_PreRender(object sender, EventArgs e)
{
    string Culture = (HttpContext.Current.Profile as ProfileCommon).Preferences.Culture;
    if (ddlChangeLanguage.Items.FindByValue(Culture) != null)
    {
        ddlChangeLanguage.SelectedValue = (HttpContext.Current.Profile as ProfileCommon).Preferences.Culture; 
    }
}

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        List<CultureInfo> languages = CultureInfo.GetCultures(CultureTypes.SpecificCultures).OrderBy(x => x.Name).ToList();

        SortedDictionary<string, string> sortedLanguages = new SortedDictionary<string, string>();

        foreach (CultureInfo language in languages)
        {
            RegionInfo regionInfo = new RegionInfo(language.Name);
            if (!sortedLanguages.ContainsKey(regionInfo.EnglishName))
            {
                sortedLanguages.Add(regionInfo.EnglishName, language.Name);
            }
        }

        foreach (KeyValuePair<string, string> language in sortedLanguages)
        {
            ddlChangeLanguage.Items.Add(new ListItem { Value = language.Value, Text = language.Key });
        }
        ddlChangeLanguage.SelectedValue = (HttpContext.Current.Profile as ProfileCommon).Preferences.Culture;
    }
    lbllanguage.Text = this.UICulture;

}

protected void ChangeLanguage_Click(object sender, EventArgs e)
{
    (HttpContext.Current.Profile as ProfileCommon).Preferences.Culture = ddlChangeLanguage.SelectedValue;
}

和我的主页继承的我的BasePage

public class BasePage : System.Web.UI.Page
{
    public BasePage()
    {
    }

    protected override void InitializeCulture()
    {            
        this.Culture = (HttpContext.Current.Profile as ProfileCommon).Preferences.Culture;
        this.UICulture = (HttpContext.Current.Profile as ProfileCommon).Preferences.Culture;
    }
}

Answer 1

您必须将字符串存储在资源文件或附属程序集中才能进行翻译：

ASP.NET Web Page Resources Overview

<asp:Button ID="Button1" runat="server" 
    Text="<%$ Resources:WebResources, Button1Caption %>" />

Answer 2

配置当前线程：

var culture = (HttpContext.Current.Profile as ProfileCommon).Preferences.Culture;
Thread.CurrentThread.CurrentCulture = culture;
Thread.CurrentThread.CurrentUICulture = culture;

Answer 3

尝试将Page_PreRender中的逻辑更改为DropDownList.SelectedIndexChanged的处理程序。

为什么语言不会在回发时发生变化？
