DownloadProgressChangedEventHandler Delegate

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

Represents the method that will handle the WebClient.DownloadProgressChanged event of a WebClient.

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

public delegate void DownloadProgressChangedEventHandler (
	Object^ sender, 
	DownloadProgressChangedEventArgs^ e
)
/** @delegate */
public delegate void DownloadProgressChangedEventHandler (
	Object sender, 
	DownloadProgressChangedEventArgs e
)
JScript supports the use of delegates, but not the declaration of new ones.

Parameters

sender

The source of the event.

e

A DownloadProgressChangedEventArgs containing event data.

When you create a DownloadProgressChangedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates. Events and Delegates

NoteNote

If the server does not send the size of the downloaded file (such as in the case of a passive FTP connection), ProgressPercentage may always be zero.

The following code example demonstrates setting an event handler for the WebClient.DownloadProgressChanged event.

No code example is currently available or this language may not be supported.
