We have moved!

You are currently looking at documentation for Umbraco 8 and older versions.
An automated guess is that docs.umbraco.com/umbraco-cms/reference/management/services/contenttypeservice/retrieving-content-type-containers could be the link to the new documentation for Umbraco 9 and newer versions.

    Retrieving content types

    Getting a single content type container

    Content types can be added either at the root level, under another content type or under a content type container (or folders as they're called in the Umbraco backoffice). The approach for getting a single container is similar to getting a single content type, meaning that you can look up a container - either by its GUID:

    // Declare the GUID ID
Guid guid = new Guid("d3b9cc9a-d471-4465-a89a-112c6bc1e5b4");

// Get a container by its GUID ID
EntityContainer container = contentTypeService.GetContainer(guid);

    or its numeric counterpart:

    // Get a container by its numeric ID
EntityContainer container = contentTypeService.GetContainer(1090);

    Getting a list of content type containers

    In the same way as you can get the content types of a container, you can get the child containers of another container. This is done by calling the GetContainers method with an array of numeric IDs:

    // Declare the array of IDs to lookup
int[] ids = new[] {1090};

// Get the child containers via the content type service
IEnumerable<EntityContainer> containers = contentTypeService.GetContainers(ids);

    Also, if the array is empty, all containers will be returned:

    // Declare the array of IDs to lookup
int[] ids = new int[0];

// Get all content type containers
IEnumerable<EntityContainer> containers = contentTypeService.GetContainers(ids);
