CommunicationObject.BeginOpen Method (TimeSpan, AsyncCallback, Object)

Begins an asynchronous operation to close a communication object within a specified interval of time.

Namespace:  System.ServiceModel.Channels
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public IAsyncResult BeginOpen(
	TimeSpan timeout,
	AsyncCallback callback,
	Object state
)

Parameters

timeout
Type: System.TimeSpan
The Timespan that specifies how long the send operation has to complete before timing out.
callback
Type: System.AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous open operation.
state
Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous open operation.

Return Value

Type: System.IAsyncResult
The IAsyncResult that references the asynchronous open operation.

Implements

ICommunicationObject.BeginOpen(TimeSpan, AsyncCallback, Object)

ExceptionCondition
ArgumentOutOfRangeException

timeout is less than zero.

InvalidOperationException

The communication object is not in a Opened or Opening state and cannot be modified.

ObjectDisposedException

The communication object is in a Closing or Closed state and cannot be modified.

CommunicationObjectFaultedException

The communication object is in a Faulted state and cannot be modified.

TimeoutException

The interval of time specified by timeout that was allotted for the operation was exceeded before the operation was completed.

The BeginOpen(TimeSpan, AsyncCallback, Object) method calls OnOpening and OnBeginOpen(TimeSpan, AsyncCallback, Object) if the communication object is initially in the Created state.

To insert processing after a communication object transitions to a closing state due to the invocation of a synchronous Open operation, use the Open method.
