How to map appsetting.json value with startup.cs in .Net Core

In this blog, I will explain, how to get appsetting.json value in Startup.cs file.

appsettings.json

{

  "ApplicationValue": {

    "filePath": "~/tempData/test.json"

  }

}

Startup.cs

public class Startup

{

 public IConfigurationRoot Configuration { get; set; }

 public Startup(IHostingEnvironment env)

 {

 var builder = new ConfigurationBuilder().AddJsonFile("appsettings.json")

 Configuration = builder.Build();

 }

 public void ConfigureServices(IServiceCollection services)

 {

 services.Configure<ApplicationSettings>

(Configuration.GetSection("ApplicationValue"));

 }

 public void Configure(IApplicationBuilder app, 

IHostingEnvironment env, ILoggerFactory loggerFactory)

 {

var applicationSettings = Configuration.Get<ApplicationValue>("ApplicationValue");

 }

}
