退出时设置当前工作目录（.NET Core）

Question

I would like to have my application set the current working directory after my application is ran, meaning that, for example:

$ pwd
/my/directory
$ dotnet MyApp.dll
$ pwd
/another/place/somewhere

How can I do that in C# using .NET Core in a cross-platform way ?

I looked at Environment.CurrentDirectory and Directory.SetCurrentDirectory but for both of them the working directory is reset to its original state when the application exits, as indicated in the documentation for Directory.SetCurrentDirectory .

When the application terminates, the working directory is restored to its original location (the directory where the process was started).

Answer 1

You can't.

The current working directory is a property of each process.

To change it in the terminal, you need to find a way to tell the terminal to do it. A program that the terminal launches can change its own current directory, but not that of the calling terminal.

This is why cd is a built-in in shells. If it was an external program, it couldn't change the working directory of the shell/terminal.
