用 Visual Studio 開發 WinForm 的視窗程式介面時，專案有很方便的方式開發多語系介面。
但是，如果是在程式啟動、載入之後，才要變更語系呢？

在網路上搜尋、嘗試了一陣子，還沒找到方便的方法，只能刻苦耐勞地去刻：

// UserViewControl.Designer.cs
        private void ReApplyResources()
        {
            System.Resources.ResourceManager resources = new System.Resources.ResourceManager( typeof( UserViewControl ) );

            local_panel.Text = resources.GetString( local_panel.Name + ".Text" );
            massage_textBox.Text = resources.GetString( massage_textBox.Name + ".Text" );
            saveAsMp4_button.Text = resources.GetString( saveAsMp4_button.Name + ".Text" );
            loadPage_progressBar.Text = resources.GetString( loadPage_progressBar.Name + ".Text" );
            this.Text = resources.GetString( this.Name + ".Text" );
        }

// UserViewControl.cs
    {
        Thread.CurrentThread.CurrentUICulture = new CultureInfo( "en" );
        // Thread.CurrentThread.CurrentUICulture = new CultureInfo( "zh-Hant" );
        // Thread.CurrentThread.CurrentUICulture = new CultureInfo( "zh-Hans" );
        
        Properties.LanguagePack.Culture = Thread.CurrentThread.CurrentUICulture;
        Properties.Resources.Culture = Thread.CurrentThread.CurrentUICulture;
        
        ReApplyResources();
    }
