Unsubscribe Method

Removes an existing subscription.

Syntax

int Unsubscribe(const QString& qsId);

Remarks

This method removes an existing subscription identified by the given Id, unsubscribing the class from the destination associated with the subscription.

Once unsubscribed, the relevant item will be removed from the Subscription* properties and the Unsubscribed event will fire.

Basic Subscriptions Example

stomp1.OnMessageIn += (s, e) => {
  Console.WriteLine("Received message from destination '" + e.Destination + "':");
  Console.WriteLine(e.Data);
};

string subId = stomp1.Subscribe("test/a/b", false);
// Some time later...
stomp1.Unsubscribe(subId);

Error Handling

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
