IDataServiceStreamProvider.GetReadStreamUri Method

Returns the URI that is used to request the media resource that belongs to the specified entity.

Namespace:  System.Data.Services.Providers
Assembly:  Microsoft.Data.Services (in Microsoft.Data.Services.dll)

Uri GetReadStreamUri(
	Object entity,
	DataServiceOperationContext operationContext
)

Parameters

entity
Type: System.Object
The entity that is a media link entry with a related media resource.
operationContext
Type: System.Data.Services.DataServiceOperationContext
The DataServiceOperationContext instance used by the data service to process the request.

Return Value

Type: System.Uri
A Uri value that is used to request the binary data stream.

The GetReadStreamUri method is called by the data service runtime to obtain the URI that clients should use when they make retrieve (i.e., GET) requests for the media resource.

The Uri value returned by the GetReadStreamUri method implementation is used as the edit-media link in the media link entry to references the location of the media resource.

When the method implementation returns null, the data service will construct a default Uri, which is usually the URI of the entity appended with /$value.
