The AudioStreamingAgent type exposes the following members.


  Name Description
AudioStreamingAgent Creates a new instance of the AudioStreamingAgent class.



  Name Description
Abort Informs the operating system that the agent is unable to perform its intended task and that it should not be launched again until the foreground application mitigates the blocking issue and reenables the agent. (Inherited from BackgroundAgent.)
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetType Gets the Type of the current instance. (Inherited from Object.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
NotifyComplete Informs the operating system that the agent has completed its intended task for the current invocation of the agent. (Inherited from BackgroundAgent.)
NotifyCompleteWithResult Informs the operating system that the agent has completed its intended task for the current invocation of the agent. Call this method after successfully handling an invocation with a result. (Inherited from BackgroundAgent.)
OnBeginStreaming Called when a new track requires audio streaming because it is about to start playing.
OnCancel Tells AudioStreamingAgent that it has been cancelled. (Overrides BackgroundAgent..::.OnCancel()()().)
ToString Returns a string that represents the current object. (Inherited from Object.)



If you want to create an application that uses MediaStreamSource streaming, then you have to extend the AudioStreamingAgent base class.

To release internal resources, OnCancel()()() must be called by derived classes. That is, the streaming agent that you create must call base.OnCancel.


This API is not supported for Silverlight 8.1 apps.
