Namespace: System.ServiceModel
Assembly: System.ServiceModel (in system.servicemodel.dll)

void Open ()

function Open ()
Not applicable.

Exception typeCondition

CommunicationException

The ICommunicationObject was unable to be opened and has entered the Faulted state.

TimeoutException

The default open timeout elapsed before the ICommunicationObject was able to enter the Opened state and has entered the Faulted state.

When an ICommunicationObject is instantiated, it begins in the Created state. In the Created state, the object can be configured (for example, properties can be set, or events can be registered), but it is not yet usable to send or receive messages. The Open method causes an ICommunicationObject to enter into the Opening state where it remains until the open operation succeeds, the open operation times out or fails and the object becomes faulted, or the ICommunicationObject is aborted.

In the Opened state, the ICommunicationObject is usable (for example, messages can be received), but it is no longer configurable.

There is also an asynchronous version of the open method that is initiated by calling BeginOpen and completed by calling EndOpen.
