c# - 使用关键字单击网页上的链接

Question

我希望能够打开至尊的网站（www.supremenewyork.com），进入任何一个标签（衬衫、夹克等）并能够输入我要点击的衬衫的关键字，然后让我的程序点击它。

我想出了如何让它自动点击结帐并填写字段。这是我们将使用的随机衬衫的 html。

https://www.supremenewyork.com/shop/all/shirts

我想点击Houndstooth Flannel Zip Up Shirt红色的

我已经读到您需要使用HTMLAgilityPack才能输入inner text's关键字。但我认为你们可以以正确的方式发送给我。

这是HTML

<article><div class="inner-article"><a style="height:150px;" href="/shop/shirts/gsfge9btl/mkza7miyc"><img width="150" height="150" src="//assets.supremenewyork.com/160974/vi/eYFAEBVxJT0.jpg" alt="Eyfaebvxjt0"></a><h1><a class="name-link" href="/shop/shirts/gsfge9btl/mkza7miyc">Houndstooth Flannel Zip Up Shirt</a></h1><p><a class="name-link" href="/shop/shirts/gsfge9btl/mkza7miyc">Red</a></p></div></article>

这是我的代码
