A ContentType corresponds to the Document Type found in the backoffice.
A ContentType corresponds to the Document Type found in the backoffice. The ContentType is a model / data definition for your content nodes. Every content node on an Umbraco web site always maps to a backing Document Type.
A Document Type is composed by Properties, which are grouped by Tabs (or PropertyGroups in the API). It can also inherit properties and tabs from other Document Types.
It is possible to link one or more Templates to a Document Type. This determines how your model/data is rendered to the user.

Properties
.Alias
Gets or Sets the Alias as a String of the ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return Aliasvar contentType =contentTypeService.Get(1234);returncontentType.Alias;
.AllowedAsRoot
Gets or Sets a Bool indicating whether this ContentType is allowed at the root. If one or more ContentTypes are set to 'AllowedAsRoot' only they are shown in the create dialog at the root level in the backoffice.
// Given a `ContentTypeService` object get ContentType by its Id and return AllowedAsRootvar contentType =contentTypeService.Get(1234);returncontentType.AllowedAsRoot;
.AllowedContentTypes
Gets or Sets an Enumerable list of ContentTypeSort objects of the ContentTypes allowed under the current ContentType.
The ContentTypeSort is an object with a lazy Id, int SortOrder and string Alias used to sort the MediaTypes within the list of AllowedContentTypes.
// Given a `ContentTypeService` object get ContentType by its Id and return AllowedContentTypesvar contentType =contentTypeService.Get(1234);returncontentType.AllowedContentTypes;
.AllowedTemplates
Gets or Sets an Enumerable list of ITemplates which are allowed for the current ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return AllowedTemplatesvar contentType =contentTypeService.Get(1234);returncontentType.AllowedTemplates;
.ContentTypeComposition
Gets a list of ContentTypes as IContentTypeComposition objects that make up a composition of PropertyGroups and PropertyTypes for the current ContentType.
The ContentTypeComposition provides a mixin-type functionality in that you can compose a ContentType of one or more other ContentTypes in a complex structure. But please be aware that the backoffice does not fully support these complex structures yet.
// Given a `ContentTypeService` object get ContentType by its Id and return ContentTypeCompositionvar contentType =contentTypeService.Get(1234);returncontentType.ContentTypeComposition;
.CompositionPropertyGroups
Gets a list of all 'PropertyGroup` objects from the composition including PropertyGroups from the current ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return CompositionPropertyGroupsvar contentType =contentTypeService.Get(1234);returncontentType.CompositionPropertyGroups;
.CompositionPropertyTypes
Gets a list of all PropertyType objects from the composition including PropertyTypes from the current ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return CompositionPropertyTypesvar contentType =contentTypeService.Get(1234);returncontentType.CompositionPropertyTypes;
.CreateDate
Gets or Sets a DateTime object, indicating then the given ContentType was created.
// Given a `ContentTypeService` object get ContentType by its Id and return CreateDatevar contentType =contentTypeService.Get(1234);returncontentType.CreateDate;
.CreatorId
Gets or Sets the Id of the User who created the ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return the Id of the Creatorvar contentType =contentTypeService.Get(1234);returncontentType.CreatorId;
.Description
Gets or Sets the Description as a String for the ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return the Descriptionvar contentType =contentTypeService.Get(1234);returncontentType.Description;
.DefaultTemplate
Gets the default Template set as an ITemplate object for this ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return the DefaultTemplatevar contentType =contentTypeService.Get(1234);returncontentType.DefaultTemplate;
.Icon
Gets or Sets the Icon as a String for the ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return the Iconvar contentType =contentTypeService.Get(1234);returncontentType.Icon;
.Id
Gets the unique ContentType Id as an Int. The ID, derived from a database identity field, isn't safe for code references as they are moved across instances. Therefore it's recommended to use Key instead.
.Key
Gets the Guid assigned to the ContentType during creation. This value is unique, and should never change, even if the content is moved between instances.
// Given a `ContentTypeService` object get ContentType by its Id and return the Keyvar contentType =contentTypeService.Get(1234);returncontentType.Key;
.Level
Gets or Sets the given ContentType level in the site hierarchy as an Int. ContentTypes placed at the root of the tree, will return 1, content right underneath will return 2, and so on.
// Given a `ContentTypeService` object get ContentType by its Id and return the Levelvar contentType =contentTypeService.Get(1234);returncontentType.Level;
.Name
Gets or Sets the name of the ContentType as a String.
// Given a `ContentTypeService` object get ContentType by its Id and return its Namevar contentType =contentTypeService.Get(1234);returncontentType.Name;
.ParentId
Gets or Sets the parent ContentType Id as an Int.
// Given a `ContentTypeService` object get ContentType by its Id and return the Id of the Parent ContentTypevar contentType =contentTypeService.Get(1234);returncontentType.ParentId;
.Path
Gets or Sets the path of the ContentType as a String. This string contains a comma separated list of the ancestors Ids including the current ContentTypes own id at the end of the string.

// Given a `ContentTypeService` object get ContentType by its Id and return its SortOrdervar contentType =contentTypeService.Get(1234);returncontentType.SortOrder;
.Thumbnail
Gets or Sets the Thumbnail as a String for the ContentType.
// Given a `ContentTypeService` object get ContentType by its Id and return the Thumbnailvar contentType =contentTypeService.Get(1234);returncontentType.Thumbnail;
