C# WebBrowser获取指定字符串的坐标

 以下代码实现WebBrowser获取指定字符串的坐标并将WebBrowser的滚动条定位到该坐标

           public void FindKeyWord(string keyWord)
           {
               WebBrowser wb = new WebBrowser();
                foreach (HtmlElement item in wb.Document.All)
                {
            if (item.InnerText != null) { if (ClearChar(item.InnerText) == keyWord) { Point point = GetPoint(item); wb.Document.Window.ScrollTo(point.X, point.Y);//滚动条至指定位置 break; } } } }
     public Point GetPoint(HtmlElement el)
        {
            Point pos = new Point(el.OffsetRectangle.Left, el.OffsetRectangle.Top);
            //循环获取父级的坐标
            HtmlElement tempEl = el.OffsetParent;
            while (tempEl != null)
            {
                pos.X += tempEl.OffsetRectangle.Left;
                pos.Y += tempEl.OffsetRectangle.Top;
                tempEl = tempEl.OffsetParent;
            }
            return pos;
        }

        public string ClearChar(string str)
        {
            str = str.Replace("
", null);
            str = str.Replace("
", null);
            str = str.Replace(" ", null);
            str = str.Replace(" ", null);
            return str;
        }
