By calling it?
通过调用它？
var path = System.Web.HttpContext.Current.Server.MapPath("default.aspx");
Make sure you add a reference to the System.Web assembly.
确保添加对 System.Web 程序集的引用。
回答by Philippe Leybaert
You should reference System.Web and call:
您应该引用 System.Web 并调用：
HttpContext.Current.Server.MapPath(...)

Maybe you could abstract this as a dependency and create an IVirtualPathResolver. This way your service classes wouldn't be bound to System.Web and you could create another implementation if you wanted to reuse your logic in a different UI technology.
也许您可以将其抽象为依赖项并创建一个 IVirtualPathResolver。这样您的服务类就不会绑定到 System.Web，如果您想在不同的 UI 技术中重用您的逻辑，您可以创建另一个实现。

You can get the base path by using the following code and append your needed path with that.
您可以使用以下代码获取基本路径，并附加您需要的路径。
string path = System.AppDomain.CurrentDomain.BaseDirectory;

Use this System.Web.Hosting.HostingEnvironment.MapPath().

Wonder why nobody mentioned it here.

Architecturally, System.web should not be referred in Business Logic Layer (BLL). Employ BLL into the solution structure to follow the separate of concern principle so refer System.Web is a bad practice. BLL should not load/run in Asp.net context. Because of the reason you should consider using of System.AppDomain.CurrentDomain.BaseDirectoryinstead of System.Web.HttpContext.Current.Server.MapPath
在体系结构上，不应在业务逻辑层 (BLL) 中引用 System.web。在解决方案结构中使用 BLL 以遵循关注点分离原则，因此参考 System.Web 是一种不好的做法。BLL 不应在 Asp.net 上下文中加载/运行。由于您应该考虑使用 ofSystem.AppDomain.CurrentDomain.BaseDirectory而不是System.Web.HttpContext.Current.Server.MapPath
