如何使用 .NETCore 在 2 个不同项目之间覆盖 appsettings.json 文件中的值

Question

I have a C# class library project and I am using appsettings.json to read values.
I have one MS Test (unit test) project and I am maintaining another appsettings.json file

appsettings.json file in C# Class library project:

{
  "name" : "jack"
}

appsettings.json file in MS Test project:

{
  "name" : "Mike"
}

My requirement is when I run the unit test the value "name" in the appsettings.json file in the C# class library project needs to be replaced with appsettings.json file in the MS Test project.

You should be using dependency injection to access configuration settings in your lib's classes; simply manually construct an instance of the configuration class with the test values you desire and pass it to the lib classes' constructors.
