我正在使用 Visual Studio 2010 中的 Web 浏览器，但无法将选项卡名称更新为网站名称。例如，当您访问 CNN.Com 之类的网站时，我希望标签页也显示“cnn.com”。顺便说一句，该项目没有使用默认的 WebBrowser 表单。请以最简单的方式解释它，因为我是 C# 新手（刚从 C++ 和 Java 迁移）所以我不熟悉使用 Windows 表单。谢谢。任何帮助表示赞赏。

假设WebBrowser是内置的WebBrowser，您可以在OnDocumentTitleChanged每次WebBrowser更改文档标题时触发事件以更改选项卡文本。

为此，在表单加载事件中，在声明浏览后，开始输入browse.DocumentTitleChanged +=，并且应该出现一个工具提示，说“插入此代码的选项卡”或类似的内容。只需 Tab 两次，Visual Studio 就会为您插入一个新方法，并带有throw new NotImplementedException();一行。删除该行并将其替换为将选项卡文本更改为浏览器的DocumentTitle.

如果您需要更多信息，我建议您查看文档：http: //msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser.aspx

虽然我相信使用事件是最好的解决方案。事件被设计为在某些重要的编程“事件”发生时执行，更改网页是此类事件的一个示例。（如果这有助于您的理解，事件大致相当于 C# 的 C++ 函数指针。虽然它们更类似于std::vector函数指针。）

为包含在两个标签中的页面文本设置 HTML 标题标签将显示在显示网页的选项卡中。
