I am getting an error when fetching data from database

Hi,

I implement one web api like this :

[Authorize]

[RoutePrefix("api/Notifications")]
public class NotificationsController : BaseController
{

private NotificationManager _notification = new NotificationManager();

[Route("")]
//api/notifications
public IEnumerable GetNotifications()
{
return GetNotifications();
}
}

This is my dataaccess layer class :

public IEnumerable GetNotifications()
{
using (KiwiDbContext context = new KiwiDbContext(_ConnectionString))
{
return context.Notifications.ToList();
}
}

This is my business layer :

public class NotificationManager
{
private DataAccess _kiwidb = new DataAccess();

public ListGetNotification()
{
return _kiwidb.GetNotifications().ToList();
}
}

This is my table :

When I execute my project get an error like this :

An unhandled exception of type 'System.StackOverflowException' occurred in Kiwi.Service.API.Controller.dll

Please give me a correct code for that.

Shiv, you are getting StackOverFlow exception because you are calling the same again and again which turns into infinite recursive function. Please try below code in your controller:

// To create NotificationManager object. It is already present in your code.
private NotificationManager _notification = new NotificationManager();

[Route("")]
//api/notifications
public IEnumerable GetNotifications()
{
return _notification.GetNotifications();
}
