WebClient.OpenReadCompleted Event

Note: This event is new in the .NET Framework version 2.0.

Occurs when an asynchronous operation to open a stream containing a resource completes.

Namespace: System.Net
Assembly: System (in system.dll)

'Declaration
Public Event OpenReadCompleted As OpenReadCompletedEventHandler
'Usage
Dim instance As WebClient
Dim handler As OpenReadCompletedEventHandler

AddHandler instance.OpenReadCompleted, handler

/** @event */
public void add_OpenReadCompleted (OpenReadCompletedEventHandler value)

/** @event */
public void remove_OpenReadCompleted (OpenReadCompletedEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

This event is raised each time an asynchronous operation to open a stream containing a resource completes. These operations are started by calling the OpenReadAsync methods.

The OpenReadCompletedEventHandler is the delegate for this event. The OpenReadCompletedEventArgs class provides the event handler with event data.

For more information about handling events, see Consuming Events.

The following code example demonstrates setting an event handler for this event.

Public Shared Sub OpenResourceForReading2(ByVal address As String)

    Dim client As WebClient = New WebClient()
    AddHandler client.OpenReadCompleted, AddressOf OpenReadCallback2
                Dim uri as Uri = New Uri(address)
    client.OpenReadAsync(uri)                        
End Sub
