Formのローカリゼーションを一括切り替え

アプリケーション内で動的にローカリゼーションを切り替えるサンプル。
子フォームや子コントロールの言語を再帰的に更新してきます。

MainForm.cs

namespace Hoge
{
    public partial class MainForm : Form
    {
        #region メニューバー「Language」
        private void englishToolStripMenuItem_Click( object sender, EventArgs e )
        {
            // メニューバー「Language」-「English」
            Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo( "" );
            this.ChangeLanguage( this, null, Thread.CurrentThread.CurrentUICulture );
        }
        private void japaneseToolStripMenuItem_Click( object sender, EventArgs e )
        {
            // メニューバー「Language」-「Japanese」
            Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo( "ja" );
            this.ChangeLanguage( this, null, Thread.CurrentThread.CurrentUICulture );
        }
        #endregion  // メニューバー「Language」

        /// <summary>
        /// フォーム、コントロール、メニューバー、ツールバー、ステータスバーの言語を再帰的に更新する
        /// </summary>
        private void ChangeLanguage( object obj, ComponentResourceManager resources, CultureInfo culture )
        {
            if ( obj is Form ) {
                Form form = obj as Form;
                ComponentResourceManager form_resources = new ComponentResourceManager( form.GetType() );
                form_resources.ApplyResources( form, "$this", culture );
                foreach ( Form fm in form.OwnedForms ) { this.ChangeLanguage( fm, form_resources, culture ); }
                foreach ( Form fm in form.MdiChildren ) { this.ChangeLanguage( fm, form_resources, culture ); }
                foreach ( Control c in form.Controls ) { this.ChangeLanguage( c, form_resources, culture ); }
            }
            else if ( obj is ToolStripItem ) {
                ToolStripItem item = obj as ToolStripItem;
                resources.ApplyResources( item, item.Name, culture );
                if ( item is ToolStripDropDownItem ) {
                    ToolStripDropDownItem dditem = item as ToolStripDropDownItem;
                    foreach ( ToolStripItem tsi in dditem.DropDownItems ) { this.ChangeLanguage( tsi, resources, culture ); }
                }
            }
            else if ( obj is Control ) {
                Control ctrl = obj as Control;
                resources.ApplyResources( ctrl, ctrl.Name, culture );
                foreach ( Control c in ctrl.Controls ) { this.ChangeLanguage( c, resources, culture ); }
                if ( ctrl is ToolStrip ) {
                    ToolStrip ts = ctrl as ToolStrip;
                    foreach ( ToolStripItem tsi in ts.Items ) { this.ChangeLanguage( tsi, resources, culture ); }
                }
            }
        }
    }
}

もっと良い方法ないかな・・・
