protected abstract IAsyncResult OnBeginOpen(
	TimeSpan timeout,
	AsyncCallback callback,
	Object state
)

Parameters

timeout: Type: System.TimeSpan
The Timespan that specifies how long the on open operation has to complete before timing out.

callback: Type: System.AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous on open operation.
