How to retrieve environment variables in project on dev .net 6

Question

I am learning about environment variables and how to use them on dev and in production on azure. So far I have some setting values in my appsettings.json file within the values section. I want to get this setting out. I tried

string value = Environment.GetEnvironmentVariable("TestValue");

doesn't return anything.

Here are my settings:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "Values": {
    "TestValue": "HelloWorld",
  },
  "AllowedHosts": "*"
}

I want to set the variable in my appsettings and then call getvariables function to get them is that possible. The reason I want to do this is because I don't want to check in my appsettings.json file on git, instead when I deploy to production, I want to add the settings myself manually on Azure using the variables.

Because your json is setting file, not a container for environment variables. — Guru Stron, Aug 11 '22 at 00:33

Create a class with name Details and declare variables

  public class Details
    {
        public string Title { get; set; }
        public string Name { get; set; }
    }

In Program.cs add the below code

var builder = WebApplication.CreateBuilder(args);
Details myDetails = builder.Configuration.GetSection("Values").Get<Details>();
var app = builder.Build();

Output:
