ChannelFactory.OnBeginOpen Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Begins an asynchronous open operation on the inner channel factory of the current channel factory that has a state object associated with it.

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

Syntax

'Declaration
Protected Overrides Function OnBeginOpen ( _
    timeout As TimeSpan, _
    callback As AsyncCallback, _
    state As Object _
) As IAsyncResult
protected override IAsyncResult OnBeginOpen(
    TimeSpan timeout,
    AsyncCallback callback,
    Object state
)

Parameters

  • timeout
    Type: System.TimeSpan
    The Timespan that specifies how long the operation has to complete before timing out.
  • state
    Type: System.Object
    An object, specified by the application, that contains state information associated with the asynchronous operation.

Return Value

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

Remarks

This method receives notification, through a callback, of the identity of the event handler for the operation. The operation is not complete until either the asynchronous open on the inner channel factory returns or the time-out occurs.
