.Parent.Parent.Parent.Parent.FullName Directory.GetParent (Directory.GetCurrentDirectory ())

会给你项目目录。

使用这个来获得项目目录(为我工作):

string projectPath = 
    Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName;

我也在找这个。我有一个运行HWC的项目，我想让网站远离应用程序树，但我不想让它在调试(或发布)目录。FWIW是公认的解决方案(这个也是)，它只标识可执行文件所在的目录。

找到我一直在用的那个目录

string startupPath = System.IO.Path.GetFullPath(".\\").

string projPath = Path.GetFullPath(@"..\..\..\");
Console.WriteLine(projPath);

这对我来说一直都很有效。试一试。

using System;
using System.IO;

// Get the current directory and make it a DirectoryInfo object.
// Do not use Environment.CurrentDirectory, vistual studio 
// and visual studio code will return different result:
// Visual studio will return @"projectDir\bin\Release\netcoreapp2.0\", yet 
// vs code will return @"projectDir\"
var currentDirectory = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory);

// On windows, the current directory is the compiled binary sits,
// so string like @"bin\Release\netcoreapp2.0\" will follow the project directory. 
// Hense, the project directory is the great grand-father of the current directory.
string projectDirectory = currentDirectory.Parent.Parent.Parent.FullName;

using System;
using System.IO;

// This will get the current WORKING directory (i.e. \bin\Debug)
string workingDirectory = Environment.CurrentDirectory;
// or: Directory.GetCurrentDirectory() gives the same result

// This will get the current PROJECT bin directory (ie ../bin/)
string projectDirectory = Directory.GetParent(workingDirectory).Parent.FullName;

// This will get the current PROJECT directory
string projectDirectory = Directory.GetParent(workingDirectory).Parent.Parent.FullName;
