如何让autocomplete在VisualStudio代码中工作？

我在编写代码时没有看到任何代码提示。我想看看我什么时候输入。在我可以使用的函数点列表之后，我什么也看不到。我只看到我在那个文件中写的东西，但我没有看到任何unity类或我使用。。。在顶端。 如何让autocomplete在visual studio代码中工作？ 我试过其他的代码编辑器，但都不起作用。请帮帮我，没有自动完成我什么都做不了我的生活被毁了。

为什么这不是质量标准？

来自文档：

如果您发现IntelliSense已停止工作，则语言服务可能会停止 不要跑。尝试重新启动VS代码，这将解决问题 问题如果安装后仍缺少IntelliSense功能 语言扩展，在该语言的存储库中打开问题 分机

在Unity中单击open c#project可查看更多信息，其中有消息显示project加载有问题
