LSClient.UnsubscribeTables Method
|
Lightstreamer Silverlight Client 1.4.2
|
|
|
Unsubscribes from a set of tables previously subscribed to the Server. The unsubscription requests are sent to the Server in a single connection. If some of the supplied tables are not currently subscribed or have already been unsubscribed, no notification is sent. If the request fails, all the tables have been unsubscribed anyway.
The method is blocking; it returns only after receiving the Server answer upon the request submission; in case a batch is open, this will happen only upon the execution of the batch.
