多个 Appsettings.json 用于命令行应用程序？

Question

I have a console app in.Net 6 and wondering how can I have multiple appSettings files?

I want to have one for

appsettings.development.json appsettings.test.json appsettings.production.json

I will be deploying the console application onto windows servers and hooking it up to a scheduled task. Depending on which environment I want a different appsettings to be used. I am not sure how to do this.

I think I would have to create an environment variable on each server to make it use the right file but hoping there is more a coding way automatically use the right appsettings file.

I found this posting that seems to be almost what I need but it is for web apps and not console apps

Automatically set appsettings.json for dev and release environments in asp.net core?

Answer 1

You can pass environment variable via line argument, like this

C:\Myapp.exe --environment Development
