- timeout
- TimeSpan
The TimeSpan that specifies how long the on open operation has to complete before timing out.
- callback
- AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous on open operation.
- state
- Object
An object, specified by the application, that contains state information associated with the asynchronous on open operation.
Returns
The IAsyncResult that references the asynchronous on open operation.
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
To insert processing after a communication object transitions to a opening state due to the invocation of a synchronous Open operation, use the Open method.
