UploadStringCompletedEventHandler Delegate

 

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

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

public delegate void UploadStringCompletedEventHandler(
	Object^ sender,
	UploadStringCompletedEventArgs^ e
)

Parameters

sender
Type: System::Object^

The source of the event.

e
Type: System.Net::UploadStringCompletedEventArgs^

A UploadStringCompletedEventArgs containing event data.

When you create a UploadStringCompletedEventHandler 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 NIB: Events and Delegates.

The following code example demonstrates asynchronously uploading a string.

void UploadStringInBackground2( String^ address )
{
   WebClient^ client = gcnew WebClient;
   Uri ^uri = gcnew Uri(address);
   String^ data = "Time = 12:00am temperature = 50";

   client->UploadStringCompleted += gcnew UploadStringCompletedEventHandler( UploadStringCallback2 );
   client->UploadStringAsync( uri, data );
}


The following method is called when the upload completes.

void UploadStringCallback2( Object^ /*sender*/, UploadStringCompletedEventArgs^ e )
{
   String^ reply = dynamic_cast<String^>(e->Result);
   Console::WriteLine( reply );
}
