Accessing values from appsettings.json in the Startup.cs

Question

I have a.Net Core project that I am trying to run from VS. I am trying to access values from appsettings.json

Let's say I have this value in appsettings.json

"Heading": 
{
  "Path": "url"
}

And I am trying to get that value in Startup.cs

   public void ConfigureServices(IServiceCollection services)
  {
    string path = Configuration["Heading:Path"];
   }

This comes up null. Am I not accessing it properly?

The Program.cs has the following...

var config = new ConfigurationBuilder()
            .SetBasePath(System.IO.Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: 
true)
            .AddJsonFile($"appsettings.{environmentName}.json", optional: 
true, reloadOnChange: true)
            .Build();

Your code seems to be fine, I just tried it myself and both path variables are set to "url".

private readonly IConfiguration _configuration;

public Startup(IConfiguration configuration)
{
  _configuration = configuration;
}

public void ConfigureServices(IServiceCollection services)
{
  string path = _configuration.GetSection("Heading:Path").Value;
  string path2 = _configuration["Heading:Path"];
}

The appsettings.json should look like this (maybe missing the outer brackets?):

{
  "Heading": {
    "Path": "url"
  }
}
