Це можна зробити за допомогою методу розширення GetConnectionString:
string conString = Microsoft
.Extensions
.Configuration
.ConfigurationExtensions
.GetConnectionString(this.Configuration, "DefaultConnection");
System.Console.WriteLine(conString);
або зі структурованим класом для DI:
public class SmtpConfig
{
public string Server { get; set; }
public string User { get; set; }
public string Pass { get; set; }
public int Port { get; set; }
}
Стартап:
public IConfigurationRoot Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// http://developer.telerik.com/featured/new-configuration-model-asp-net-core/
// services.Configure<SmtpConfig>(Configuration.GetSection("Smtp"));
Microsoft.Extensions.DependencyInjection.OptionsConfigurationServiceCollectionExtensions.Configure<SmtpConfig>(services, Configuration.GetSection("Smtp"));
А потім у домашньому контролері:
public class HomeController : Controller
{
public SmtpConfig SmtpConfig { get; }
public HomeController(Microsoft.Extensions.Options.IOptions<SmtpConfig> smtpConfig)
{
SmtpConfig = smtpConfig.Value;
} //Action Controller
public IActionResult Index()
{
System.Console.WriteLine(SmtpConfig);
return View();
}
з цим у appsettings.json:
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=aspnet-WebApplica71d622;Trusted_Connection=True;MultipleActiveResultSets=true"
},
"Smtp": {
"Server": "0.0.0.1",
"User": "user@company.com",
"Pass": "123456789",
"Port": "25"
}
