UploadDataCompletedEventHandler Delegate
Represents the method that will handle the UploadDataCompleted event of a WebClient.
Assembly: System (in System.dll)
public delegate void UploadDataCompletedEventHandler( Object sender, UploadDataCompletedEventArgs e )
Parameters
- sender
- Type: System.Object
The source of the event.
- e

A UploadDataCompletedEventArgs containing event data.
When you create a UploadDataCompletedEventHandler 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 D98FD58B-FA4F-4598-8378-ADDF4355A115.
The following code example demonstrates asynchronously uploading data.
public static void UploadDataInBackground2 (string address)
{
WebClient client = new WebClient ();
Uri uri = new Uri(address);
string text = "Time = 12:00am temperature = 50";
byte[] data = System.Text.Encoding.UTF8.GetBytes (text);
string method = "POST";
client.UploadDataCompleted += new UploadDataCompletedEventHandler (UploadDataCallback2);
client.UploadDataAsync (uri, method, data);
}
The following method is called when the upload completes.
