WPF WebBrowser在浏览器中禁用网页的鼠标事件？

private void DisableMouseEvents()
{
    // 获取WebBrowser控件的Document对象
    mshtml.HTMLDocument document = webBrowser.Document as mshtml.HTMLDocument;
    
    if (document != null)
    {
        // 注册事件处理程序
        document.onmousedown += new mshtml.HTMLDocumentEvents2_onmousedownEventHandler(OnMouseDown);
        document.onmouseup += new mshtml.HTMLDocumentEvents2_onmouseupEventHandler(OnMouseUp);
        document.onmousemove += new mshtml.HTMLDocumentEvents2_onmousemoveEventHandler(OnMouseMove);
    }
}

private bool OnMouseDown(mshtml.IHTMLEventObj e)
{
    // 禁用鼠标按下事件
    e.returnValue = false;
    e.cancelBubble = true;
    return false;
}

private bool OnMouseUp(mshtml.IHTMLEventObj e)
{
    // 禁用鼠标释放事件
    e.returnValue = false;
    e.cancelBubble = true;
    return false;
}

private bool OnMouseMove(mshtml.IHTMLEventObj e)
{
    // 禁用鼠标移动事件
    e.returnValue = false;
    e.cancelBubble = true;
    return false;
}
