The entity that is a media link entry with a related media resource.
- Type: System.String
The eTag value sent as part of the HTTP request that is sent to the data service.
- Type: System.Nullable<Boolean>
A nullable Boolean value that determines what kind of conditional request was issued to the data service, which is true when the eTag was sent in an If-Match header, false when the eTag was sent in an If-None-Match header, and null when the request was not conditional and no eTag was included in the request.
eTag is the value of an If-Match or If-None-Match header.
The method is called by the data service runtime to acquire the stream that the data service returns to the client when the client requests the media resource for the specified entity, which is a media link entry. For more information, see Streaming Provider (WCF Data Services).
