The Media class represents a single item in the media tree.
The Media class represents a single item in the media tree, its values are fetched directly from the database, not from the cache. Notice the Media class should strictly be used for CRUD operations. Media is already stored in cache, so for querying Media you'd want to use the IUmbracoContext.IPublishedMediaCache to get the media. Then one would use LINQ to query and filter the collection.

new Media(string name, IMedia parent, IMediaType mediaType)
Constructor for creating a new Media object where the necessary parameters are the name of the Media, the parent of the Media as an IMedia object and the MediaType as an IMediaType object for the Media being created.
new Media(string name, IMedia parent, IMediaType mediaType, IPropertyCollection properties)
Constructor for creating a new Media object where the necessary parameters are the name of the Media, the parent of the Media as an IMedia object, the MediaType as an IMediaType object and a IPropertyCollection for the Media being created.
new Media(string name, int parentId, IMediaType mediaType)

Properties
.CreateDate
Gets or Sets a DateTime object, indicating then the given Media was created.
// Given a `MediaService` object get Media by its Id and return CreateDatevar media =mediaService.GetById(1234);returnmedia.CreateDate;
.CreatorId
Gets or Sets the Id of the User as an int who created the Media.
// Given a `MediaService` object get Media by its Id and return the Id of the Creatorvar media =mediaService.GetById(1234);returnmedia.CreatorId;
.ContentType

// Given a `MediaService` object get Media by its Id and return the Id of the MediaTypevar media =mediaService.GetById(1234);returnmedia.ContentTypeId;
.Id
Returns the unique Media Id as a Int, this ID is based on a Database identity field, and is therefore not safe to reference in code which are moved between different instances, use Key instead.
.Key
Returns the Guid assigned to the Media during creation. This value is unique, and should never change, even if the Media is moved between instances.
// Given a `MediaService` object get Media by its Id and return the Keyvar media =mediaService.GetById(1234);returnmedia.Key;
.Level
Gets or Sets the given Media level in the site hierarchy as an Int. Media placed at the root of the tree, will return 1, Media right underneath will return 2, and so on.
// Given a `MediaService` object get Media by its Id and return the Levelvar media =mediaService.GetById(1234);returnmedia.Level;
.Name
Gets or Sets the name of the Media as a String.

.Path
Gets or Sets the path of the Media as a String. This string contains a comma separated list of the ancestors Ids including the current medias own id at the end of the string.
// Given a `MediaService` object get Media by its Id and return the Pathvar media =mediaService.GetById(1234);returnmedia.Path;
.Properties
Gets or Sets the PropertyCollection object, which is a collection of Property objects. Each property corresponds to a PropertyType, which is defined on the MediaType.
// Given a `MediaService` object get Media by its Id and loop through all Propertiesvar media =mediaService.GetById(1234);foreach(var property inmedia.Properties){string alias =property.Alias;object value =property.GetValue();}

// Given a `MediaService` object get Media by its Id and return UpdateDatevar media =mediaService.GetById(1234);returnmedia.UpdateDate;
.Version
Returns the current Version Id as a Guid, For each change made to a Media item, its values are stored under a new Version. This version is identified by a Guid.
Methods
.ChangeContentType(IMediaType mediaType)
Changes the IMediaType for the current Media object and removes PropertyTypes and Properties, which are not part of the new MediaType. Please use with caution as this remove differences between the new and old MediaType.
// Given a `ContentTypeService` object get the MediaType that we're changing to,// get the Media from the `MediaService` for which we want to change MediaType for,// and then save the Media through the MediaService.var mediaType =contentTypeService.GetMediaType(1122);var media =mediaService.GetById(1234);media.ChangeContentType(mediaType);mediaService.Save(media);
.GetCreatorProfile()

// Given a `MediaService` object get Media by its Id and get the `IProfile` of the Creatorvar media =mediaService.GetById(1234);var profile =media.GetCreatorProfile();var id =profile.Id;string name =profile.Name;
.GetValue(string propertyTypeAlias)
Gets the value of a Property as an Object.
// Given a `MediaService` object get Media by its Id and get a value by aliasvar media =mediaService.GetById(1234);object value =media.GetValue("height");int text =int.Parse(value.ToString());
.GetValue< TPassType >(string propertyTypeAlias)
Gets the value of a Property as the defined type 'TPassType'.
// Given a `MediaService` object get Media by its Id and get a value by alias while specifying the return typevar media =mediaService.GetById(1234);int value =media.GetValue<int>("height");
.HasProperty(string propertyTypeAlias)

// Given a `MediaService` object get Media by its Id and check if certain properties existvar media =mediaService.GetById(1234);bool tagsExists =media.HasProperty("myTagProperty");bool textExists =media.HasProperty("altText");
.SetValue(string propertyTypeAlias, object value)
Sets the value of a property by its alias.
// Given a `MediaService` object get Media by its Id, set a few values// and saves the Media through the `MediaService`var media =mediaService.GetById(1234);media.SetValue("altText","Alternative text for this media item");media.SetValue("date",DateTime.Now);mediaService.Save(media);
It is worth noting that it is also possible to pass a HttpPostedFile, HttpPostedFileBase or HttpPostedFileWrapper to the SetValue method, so it can be used for uploads.
.ToXml()
Returns an XElement containing the Media data, based off the latest changes. When the Media item is saved the xml is stored in the database.
