ICommunicationObject.BeginOpen Method (TimeSpan, AsyncCallback, Object)
Begins an asynchronous operation to open a communication object within a specified interval of time.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
IAsyncResult BeginOpen( TimeSpan timeout, AsyncCallback callback, Object state )
- Type: System.TimeSpan
The Timespan that specifies how long the send operation has to complete before timing out.
- Type: System.AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous open operation.
- Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous open operation.
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.Notes to Implementers
The operation must throw a TimeoutException if the specified timeout is exceeded.
