Begins an asynchronous operation to open a communication object.

| BeginOpen(TimeSpan, AsyncCallback, Object) |
Begins an asynchronous operation to open a communication object within a specified interval of time. |
BeginOpen(AsyncCallback, Object)
- Source:
- CommunicationObject.cs
Begins an asynchronous operation to open a communication object.
public:
virtual IAsyncResult ^ BeginOpen(AsyncCallback ^ callback, System::Object ^ state);public IAsyncResult BeginOpen (AsyncCallback callback, object state);abstract member BeginOpen : AsyncCallback * obj -> IAsyncResult
override this.BeginOpen : AsyncCallback * obj -> IAsyncResultPublic Function BeginOpen (callback As AsyncCallback, state As Object) As IAsyncResultParameters
- callback
- AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous open operation.
- state
- Object
An object, specified by the application, that contains state information associated with the asynchronous open operation.
Returns
The IAsyncResult that references the asynchronous open operation.
Implements
Exceptions
The communication object is in a Faulted state and cannot be modified.
The default interval of time that was allotted for the operation was exceeded before the operation was completed.
Remarks
The OnBeginOpen(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.

- Source:
- CommunicationObject.cs
Begins an asynchronous operation to open a communication object within a specified interval of time.

override this.BeginOpen : TimeSpan * AsyncCallback * obj -> IAsyncResultPublic Function BeginOpen (timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResultParameters
- timeout
- TimeSpan
The TimeSpan that specifies how long the send operation has to complete before timing out.
- callback
- AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous open operation.
- state
- Object
An object, specified by the application, that contains state information associated with the asynchronous open operation.
Returns
The IAsyncResult that references the asynchronous open operation.
