Getting the service

Services property

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

IDataTypeService dataTypeService = Services.DataTypeService;

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 IDataTypeService interface in your constructor:

public class MyClass
{

    private IDataTypeService _dataTypeService;
    
    public MyClass(IDataTypeService dataTypeService)
    {
        _dataTypeService = dataTypeService;
    }

}

Static accessor

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

IDataTypeService dataTypeService = Umbraco.Core.Composing.Current.Services.DataTypeService;
