Examples on how to retrieve content types and content type containers using the ContentTypeService.
Learn how to work with Content Types through the Content Type Service.
Getting a single content type
A given content type has a few different unique identifier that we can use to look it up via the content type service. For instance, if we know the GUID of the content type, we can look it up like this:
// Declare the GUID IDGuid guid =newGuid("796a8d5c-b7bb-46d9-bc57-ab834d0d1248");// Get a reference to the content type by its GUID IDIContentType contentType =_contentTypeService.Get(guid);
Although the use of a GUID is preferable, you can also use it's numeric ID:
// Get a reference to the content type by its numeric IDIContentType contentType =_contentTypeService.Get(1234);
Finally, you can also look up a content type by its alias:
// Get a reference to the content type by its aliasIContentType contentType =_contentTypeService.Get("home");
Getting a list of content types
As content types are stored in a hierarchical list with folders (containers), there is also multiple ways to can get content types. If you are looking for a flat list of all content types, you can use the GetAll method:
// Get a collection of all content typesIEnumerable<IContentType> contentTypes =_contentTypeService.GetAll();
The service also have GetMany-methods to get a collection of content types by their GUIDs IDs or numeric IDs:
// Get a collection of two specific content types by their GUIDs IDsIEnumerable<IContentType> contentTypes =_contentTypeService.GetMany(new[] {newGuid("2b54088e-d355-4b9e-aa4b-5aec4b3f87eb"),newGuid("859c5916-19d8-4a72-9bd0-5641ad503aa9")});
// Get a collection of two specific content types by their numeric IDsIEnumerable<IContentType> contentTypes =_contentTypeService.GetMany(1234,1235);
To get a list of all Content Types of another content type, you can use the GetChildren method. This can be done by specifying the numeric ID or the GUID:
// Get a collection of content types of a specific content typeIEnumerable<IContentType> contentTypes =_contentTypeService.GetChildren(1232);
In some cases it can be useful to check if a content type has children. The HasChildren method can be used to check whether a content type has children.
// Check if there are childrenbool hasChildren =_contentTypeService.HasChildren(Guid.Parse("2b54088e-d355-4b9e-aa4b-5aec4b3f87eb"));
Although the use of a GUID is preferable, you can also use it's numeric ID:
// Check if there are childrenbool hasChildren =_contentTypeService.HasChildren(1234);
Retrieving content type container
Getting a single content type container
You can add content types in three different ways. At the root level, under another content type, or under a container (which is a folder). To obtain a single container, the process is similar to obtaining a single content type. This means that you can search for a container either by its GUID:
// Declare the GUID IDGuid guid =newGuid("d3b9cc9a-d471-4465-a89a-112c6bc1e5b4");// Get a container by its GUID IDEntityContainer container =_contentTypeService.GetContainer(guid);
or its numeric counterpart:
// Get a container by its numeric IDEntityContainer 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 lookupint[] ids =new[] {1090};// Get the child containers via the content type serviceIEnumerable<EntityContainer> containers =_contentTypeService.GetContainers(ids);
Also, if the array is empty, all containers will be returned:
// Declare the array of IDs to lookupint[] ids =newint[0];// Get all content type containersIEnumerable<EntityContainer> containers =_contentTypeService.GetContainers(ids);
