C# 如何删除FontEditor标题栏

调出ColorEditor需要实现IwinowsFormsEditor服务和IServiceProvider。“颜色”对话框具有很大的灵活性，可以集成到下拉列表中。但FontEditor窗口已经内置了关闭按钮和标题栏。为什么MS在对话框中实现如此不同的东西？如何摆脱关闭按钮和标题栏？调出FontEditor是否必须使用IwinDownFormsEditor服务和IServiceProvider

为什么MS在对话框中实现如此不同的东西

我还没有检查反射的代码。我对它不感兴趣。我 就像抱怨一样

如何摆脱关闭按钮和标题栏

FontEditor只是一个弹出窗口，我现在不可能这样做

调出FontEditor是否必须使用IwinDownFormsEditor服务和IServiceProvider

我试过了，似乎我们两个都要用，尽管 实际上没有调用IWINDOWSFormsEditor服务

    private void btnFont_Click(object sender, EventArgs e)
    {
        Point location = base.PointToScreen(new Point(btnFont.Bounds.Location.X, btnFont.Bounds.Location.Y + btnFont.Bounds.Height));
        DropDownManager myFontDialog = new DropDownManager(btnFont, new Rectangle(location, new Size(0, 0)), false, false, "Please choose...");                     
        object objectValue = new FontEditor().EditValue(myFontDialog, previousChoosenFont);
        if (objectValue != null)
        {
            previousChoosenFont = (Font)objectValue;
        }
        btnFont.Font = previousChoosenFont;
    }

   internal class DropDownManager : IWindowsFormsEditorService, IServiceProvider, IDisposable
    {
       ///......
       void IWindowsFormsEditorService.CloseDropDown()
        {
            throw new NotSupportedException();
        }

        void IWindowsFormsEditorService.DropDownControl(Control dropDownControl)
        {            
            throw new NotSupportedException();
        }

        DialogResult IWindowsFormsEditorService.ShowDialog(Form dialog)
        {
            throw new NotSupportedException();
        }

        object IServiceProvider.GetService(Type serviceType)
        {
            object result = null;
            if (serviceType.Equals(typeof(IWindowsFormsEditorService)))
            {
                result = this;
            }
            return result;
        }
       ///.....
}
