运行时本地化

我用C＃创建了Windows Form程序。 本地化有一些问题。 我有3种语言的资源文件。 我想单击每个语言按钮并在运行时更改语言。 当我在InitializeComponent()之前更改语言时，它可以工作。 但是，当我点击按钮时，它不起作用。 我正在使用此代码。

 private void RussianFlag_Click(object sender, EventArgs e) { Thread.CurrentThread.CurrentUICulture = new CultureInfo("ru-RU"); } 

Answer 1

您需要重新加载它的控件以反映新文化值

 ComponentResourceManager resources = new ComponentResourceManager(typeof(Form1)); 

然后你必须使用resources.ApplyResources申请每个控件

Answer 2

我编写了一个具有以下function的RuntimeLocalizer类：

• 更改和更新表单中所有Control和SubControl的本地化
• 还会更改所有MenuStrip的所有SubItem的本地化

用法示例： RuntimeLocalizer.ChangeCulture(MainForm, "en-US");

---

 using System.Windows.Forms; using System.Globalization; using System.Threading; using System.ComponentModel; 

---

 public static class RuntimeLocalizer { public static void ChangeCulture(Form frm, string cultureCode) { CultureInfo culture = CultureInfo.GetCultureInfo(cultureCode); Thread.CurrentThread.CurrentUICulture = culture; ComponentResourceManager resources = new ComponentResourceManager(frm.GetType()); ApplyResourceToControl(resources, frm, culture); resources.ApplyResources(frm, "$this", culture); } private static void ApplyResourceToControl(ComponentResourceManager res, Control control, CultureInfo lang) { if (control.GetType() == typeof(MenuStrip)) // See if this is a menuStrip { MenuStrip strip = (MenuStrip)control; ApplyResourceToToolStripItemCollection(strip.Items, res, lang); } foreach (Control c in control.Controls) // Apply to all sub-controls { ApplyResourceToControl(res, c, lang); res.ApplyResources(c, c.Name, lang); } // Apply to self res.ApplyResources(control, control.Name, lang); } private static void ApplyResourceToToolStripItemCollection(ToolStripItemCollection col, ComponentResourceManager res, CultureInfo lang) { for (int i = 0; i < col.Count; i++) // Apply to all sub items { ToolStripItem item = (ToolStripMenuItem)col[i]; if (item.GetType() == typeof(ToolStripMenuItem)) { ToolStripMenuItem menuitem = (ToolStripMenuItem)item; ApplyResourceToToolStripItemCollection(menuitem.DropDownItems, res, lang); } res.ApplyResources(item, item.Name, lang); } } } 

Answer 3

更改CurrentUICulture不会自动重新加载资源。 您需要手动执行它（http://msdn.microsoft.com/en-us/magazine/cc163609.aspx#S8）

您可以将与本地化相关的代码从InitializeComponent（）复制到另一个函数中：

 void LoadResources(){ this.Title = MyApp.Resources.MainFormCaption; this.lblWelcomeMessage.Text = MyApp.Resources.UserWelcome; }

谢谢V4Vendetta和其他人..解决方案是……

 private void RussianFlag_Click(object sender, EventArgs e) { if (currentLanguage != "RUS") { Thread.CurrentThread.CurrentUICulture = new CultureInfo("ru-RU"); ChangeLanguage("ru-RU"); } } 

…. ….

 private void ChangeLanguage(string lang) { foreach (Control c in this.Controls) { ComponentResourceManager resources = new ComponentResourceManager(typeof(Form1)); resources.ApplyResources(c, c.Name, new CultureInfo(lang)); if (c.ToString().StartsWith("System.Windows.Forms.GroupBox")) { foreach (Control child in c.Controls) { ComponentResourceManager resources_child = new ComponentResourceManager(typeof(Form1)); resources_child.ApplyResources(child, child.Name, new CultureInfo(lang)); } } } }
