运行时的本地化

Question

我已经用C#创建了Windows Form程序。我对本地化有一些问题。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()之前改变语言时，它起作用了。但是当我点击按钮时，它不起作用。我正在使用这个代码。

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

Answer 1

您将需要重新加载控件以反映新区域性值

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

然后，您必须使用resources.ApplyResources为每个控件申请

我编写了一个具有以下特性的RuntimeLocalizer类：

• 更改和更新表单中所有Control和SubControl的本地化
• 还更改所有MenuStrips

的所有SubItem的本地化

使用示例：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);
        }
    }
}

更改CurrentUICulture不会自动重新加载资源。您需要手动执行(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：

void LoadResources(){

    this.Title = MyApp.Resources.MainFormCaption;
    this.lblWelcomeMessage.Text = MyApp.Resources.UserWelcome;

}
