I will show how to get your data from appsettings.json and e.g. show it on view.
First, go to an appsettings.json and add the entry. In my case, I added:
“Message”: “Message from appsettings.json”
All appsettings.json code looks like this:
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"AllowedHosts": "*",
"Message": "Message from appsettings.json"
}
Second step, changes to the controller, let’s take a sample HomeController.
So inject IConfiguration in HomeController constructor, assign to _config field and add ‘using Microsoft.Extensions.Configuration;’
HomeController code:
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
namespace WebApplicationTest.Controllers
{
public class HomeController : Controller
{
private readonly IConfiguration _config;
public HomeController(IConfiguration config)
{
_config = config;
}
public IActionResult Index()
{
ViewData["Message1"] = _config["Message"];
// or
ViewData["Message2"] = _config.GetSection("Message").Value;
return View();
}
}
}
For example, we can use ViewData to assign data from appsettings.json in Index() method:
ViewData[“Message1”] = _config[“Message”];
or
ViewData[“Message2”] = _config.GetSection(“Message”).Value;
public IActionResult Index()
{
ViewData["Message1"] = _config["Message"];
// or
ViewData["Message2"] = _config.GetSection("Message").Value;
return View();
}
And last part – View:
Just add this lines to the view (Index.cshtml):
@ViewData[“Message1”]
@ViewData[“Message2”]
<div>@ViewData["Message1"]</div>
<div>@ViewData["Message2"]</div>
Run application to see result:
That’s all 😉
