如何以编程方式控制Firefox,最好使用C#应用程序？

Question

我正在寻找一个打开Firefox实例的程序,即包含我各种登录信息的Firefox的默认实例,然后只需切换几个站点.我有点能够使用以下代码执行此操作:

System.Diagnostics.Process.Start("firefox.exe", "thisIsMyURL");

但是,由于我确信您大部分都知道,这只会打开一个新的Firefox进程,并将给定的URL作为要打开的默认站点.为了做我想做的事情,我基本上必须打开一个新的Firefox进程,在页面上执行我需要的操作,终止进程,并为我需要的每个页面重复此操作.这不太理想.所以,我希望有人知道通过API或库或其他方式以编程方式控制Firefox的方法.我在谷歌上搜索过,到目前为止只发现过时的解决方案并没有真正解决我的问题.

一如既往,感谢您的帮助!你能提供的一切都值得赞赏.

您可以将 Selenium WebDriver 用于 C#。

这是一个跨平台 API，允许您使用 Java、C# 等 API 来控制各种浏览器。

附上带有 Selenium WebDriver 测试的 C# 代码。

using System.Text.RegularExpressions;
