Definition

Inserts processing after a communication object transitions to the closing state due to the invocation of an asynchronous close operation.
protected:
abstract IAsyncResult ^ OnBeginClose(TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state);
protected abstract IAsyncResult OnBeginClose (TimeSpan timeout, AsyncCallback callback, object state);
abstract member OnBeginClose : TimeSpan * AsyncCallback * obj -> IAsyncResult
Protected MustOverride Function OnBeginClose (timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResult
Parameters
- timeout
- TimeSpan
The TimeSpan that specifies how long the on close operation has to complete before timing out.
- callback
- AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous on close operation.
- state
- Object
An object, specified by the application, that contains state information associated with the asynchronous on close operation.
Returns
The IAsyncResult that references the asynchronous on close 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
The BeginClose method calls OnBeginClose if the communication object is initially in the Opened state.
To insert processing after a communication object transitions to a closing state due to the invocation of a synchronous Close operation, use the OnClose(TimeSpan) method.
