您可以使用var assocs = _context.Assoc.ToList() .Where(x => x.Model == model) .Where(predicate);方法使用p.price b CSS选择器提取此价格，例如

String html = "<p class=\"price asking help \">\n" +
            "                <span class=\"title\">Asking Price:</span><b>$349,900<span class=\"help\" title=\"The total asking price of the business for sale.\"><i class=\"fa fa-question-circle\"></i></span></b>\n" +
            "            </p>";

Document doc = Jsoup.parse(html);

String price = doc.select("p.price b").first().text();

System.out.println(price);

输出

$349,900
