Whenever you need to modify an entity that Umbraco stores in the database, there is a service API available to help you. This means that you can create, update and delete any of the core Umbraco entities directly from your custom code.
To use the service APIs you must first access them. This is done through what is known as the ApplicationContext which provides access to everything related to the Umbraco application.
If you are accessing Umbraco services inside your own controller class, you get access to all services through Services by inheriting from one of Umbraco's base controller classes:
public class EventController : Umbraco.Web.Mvc.SurfaceController
{
public Action PerformAction()
{
var content = Services.ContentService.GetById(1234);
}
}If we for instance subscribe to the ApplicationStarted event we get access to the ApplicationContext, which then provides a .Services class through which all the available services can be used.
public class EventHandler : Umbraco.Core.ApplicationEventHandler
{
protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
{
var c = applicationContext.Services.ContentService.GetById(1234);
applicationContext.Services.ContentService.Delete(c);
}
}There is full API coverage of all Umbraco core entities:
