推荐答案

为了让它像桌面浏览器一样工作，你可以实现一个 stack.

To make it work like a desktop browser you can implement a stack.

您将前后放置两个按钮.当用户导航到浏览器中的下一个 URL 时，您将它们推入历史堆栈，当他想通过按后退按钮返回时，您导航到历史堆栈中的第一个 url以编程方式从历史堆栈中弹出它，这样他就可以导航回来，直到堆栈中有一些URL.同样，对于前进，您将 URL 推入 前进堆栈，因为他向后导航，并且每当他按下前进按钮时，您就会导航到 前进堆栈 中的第一个元素，并且弹出它，依此类推，直到您在前向堆栈中留下网址.一旦他导航到您未从 forward stack 导航的某个 url，那么您清空前向堆栈并在他向后移动时再次填充.

You will put two buttons back and forward. As the user navigate to next URL in browser you push them into history stack and when he wants to get back by pressing back button you navigate to the first url in the history stack programmatically and pop it up from the history stack so he can navigate back till stack has some URLs in it. Similarly for forward you push URLs into forward stack as he navigates back and and whenever he presses forward button you navigate to first element in forward stack and pop it up and so on till you have urls left in forward stack. Once he navigates to some url which is not navigated from forward stack by you then you empty the forward stack and fill it again when he moves back.

通过这种方式，您甚至可以在列表中或以您喜欢的方式显示历史网址.

This way you can even show history urls in a list or however you like.

关于取消导航，这是您问题下评论中问题链接的代码，它应该可以工作.

About navigation cancel, here is the code from the link to question in the comments under your question, it should work.

private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    //cancel navigation
     e.Cancel = true;

}
