IDataServiceStreamProvider.GetReadStreamUri Method

Definition

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

public:
 Uri ^ GetReadStreamUri(System::Object ^ entity, System::Data::Services::DataServiceOperationContext ^ operationContext);
public Uri GetReadStreamUri (object entity, System.Data.Services.DataServiceOperationContext operationContext);
abstract member GetReadStreamUri : obj * System.Data.Services.DataServiceOperationContext -> Uri
Public Function GetReadStreamUri (entity As Object, operationContext As DataServiceOperationContext) As Uri

Parameters

entity
Object

The entity that is a media link entry with a related media resource.

operationContext
DataServiceOperationContext

The DataServiceOperationContext instance used by the data service to process the request.

Returns

Uri

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

Remarks

The GetReadStreamUri method is called by the data service runtime to obtain the URI that clients should use when they make retrieve (that is, 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.
