DownloadProgressChangedEventHandler Delegate

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

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

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

Syntax

'Declaration
Public Delegate Sub DownloadProgressChangedEventHandler ( _
    sender As Object, _
    e As DownloadProgressChangedEventArgs _
)

public delegate void DownloadProgressChangedEventHandler(
    Object sender,
    DownloadProgressChangedEventArgs e
)

Parameters

sender
Type: System.Object
The source of the event.

e
Type: System.Net.DownloadProgressChangedEventArgs
A DownloadProgressChangedEventArgs containing event data.

Remarks

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.

Note:
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.
