如何在asp.net core 中获取项目的根目录.Directory.GetCurrentDirectory() 在 Mac 上似乎无法正常工作

问题描述

我的项目的文件夹结构如下:

My project has a folder structure to the tune of:

• 项目，
• 项目/数据
• 项目/引擎
• 项目/服务器
• 项目/前端

在服务器中(在 Project/Server 文件夹中运行)我指的是这样的文件夹:

In the server (running in the Project/Server folder) I refer to the folder like this:

var rootFolder = Directory.GetCurrentDirectory();
rootFolder = rootFolder.Substring(0,
            rootFolder.IndexOf(@"Project", StringComparison.Ordinal) + @"Project".Length);
PathToData = Path.GetFullPath(Path.Combine(rootFolder, "Data"));

var Parser = Parser();
var d = new FileStream(Path.Combine(PathToData, $"{dataFileName}.txt"), FileMode.Open);
var fs = new StreamReader(d, Encoding.UTF8);

在我的 Windows 机器上，此代码运行良好，因为 Directory.GetCurrentDirectory() 引用了当前文件夹，并且正在执行

On my windows machine this code works fine since Directory.GetCurrentDirectory() reffered to the current folder, and doing

rootFolder.Substring(0, rootFolder.IndexOf(@"Project", StringComparison.Ordinal) + @"Project".Length); 

让我获得项目的根文件夹(不是 bin 或 debug 文件夹).但是当我在 mac 上运行它时，它得到了Directory.GetCurrentDirectory()"将我发送到/usr//[something else].它不是指我的项目所在的文件夹.

gets me the root folder of the project (not the bin or debug folders). But when I ran it on a mac it got "Directory.GetCurrentDirectory()" sent me to /usr//[something else]. It didn't refer to the folder where my project lies.

在我的项目中查找相对路径的正确方法是什么?我应该在哪里存储数据文件夹，以便解决方案中的所有子项目都可以轻松访问它 - 特别是 kestrel 服务器项目?我更喜欢不必将其存储在 wwwroot 文件夹中，因为数据文件夹由团队中的其他成员维护，而我只想访问最新版本.我有哪些选择?

What is the correct way to find relative paths in my project? Where should I store the data folder in a way that it is easily accessible to all the sub projects in the solution - specifically to the kestrel server project? I prefer to not have to store it in the wwwroot folder because the data folder is maintained by a different member in the team, and I just want to access the latest version. What are my options?

推荐答案

取决于您在 kestrel 管道中的位置 - 如果您有权访问 IConfiguration (Startup.cs 构造函数)或 IWebHostEnvironment(以前的IHostingEnvironment)你可以注入IWebHostEnvironment进入您的构造函数或仅从配置中请求密钥.

Depending on where you are in the kestrel pipeline - if you have access to IConfiguration (Startup.cs constructor) or IWebHostEnvironment (formerly IHostingEnvironment) you can either inject the IWebHostEnvironment into your constructor or just request the key from the configuration.

public Startup(IConfiguration configuration, IWebHostEnvironment env)
{
     var contentRoot = env.ContentRootPath;
}

在 Startup.cs 构造函数中使用 IConfiguration

public Startup(IConfiguration configuration)
{
     var contentRoot = configuration.GetValue<string>(WebHostDefaults.ContentRootKey);
}
