    Getting the service

    Services property

    If you wish to use use the tag service in a class that inherits from one of the Umbraco base classes (eg. SurfaceController, UmbracoApiController or UmbracoAuthorizedApiController), you can access the tag service through a local Services property:

    ITagService tagService = Services.TagService;
    

    Dependency Injection

    In other cases, you may be able to use Dependency Injection. For instance if you have registered your own class in Umbraco's dependency injection, you can specify the ITagService interface in your constructor:

    public class MyClass
    {
    
        private ITagService _tagService;
    
    	public MyClass(ITagService tagService)
    	{
    		_tagService = tagService;
    	}
    
    }
    

    Static accessor

    If neither a Services property or Dependency Injection is available, you can also reference the static Current class directly:

    ITagService tagService = Umbraco.Core.Composing.Current.Services.TagService;
