.NET 5 启动应用程序时出错。 目录未找到异常

Question

我使用 .NET 5 在 C# 中开发了一个 Web API，它在我的本地机器上运行良好，但在服务器上，它不起作用。 使用详细错误后，错误是服务器上不存在资源文件夹，而它确实存在，我确定我将它与项目一起发布。

我联系了服务器支持，他们告诉我我们无法帮助您，问题出在您的项目上。 任何帮助表示赞赏。

Answer 1

这个错误意味着

h:\\root....资源

文件不会与您的项目一起发布到服务器。

尝试找到文件位置并发布它。

查看官方教程发布你的项目：

我无法解决问题，但是当我删除资源文件夹并使用 wwwroot 时，项目成功运行
