为什么语言不会在回发时发生变化？

我的下拉列表中有一个语言列表，其中包含en-NZ，en-US等forms的值，但该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，并告诉我改变我的页面语言我做错了什么

而且我的lbllanguage.Text会在第二次回发时发生变化，所以它假设在第一次单击时更改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 languages = CultureInfo.GetCultures(CultureTypes.SpecificCultures).OrderBy(x => x.Name).ToList(); SortedDictionary sortedLanguages = new SortedDictionary(); foreach (CultureInfo language in languages) { RegionInfo regionInfo = new RegionInfo(language.Name); if (!sortedLanguages.ContainsKey(regionInfo.EnglishName)) { sortedLanguages.Add(regionInfo.EnglishName, language.Name); } } foreach (KeyValuePair 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inheritance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：

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。
