UploadStringCompletedEventHandler Delegate
Represents the method that will handle the UploadStringCompleted event of a WebClient.
Assembly: System (in System.dll)
'Declaration Public Delegate Sub UploadStringCompletedEventHandler ( _ sender As Object, _ e As UploadStringCompletedEventArgs _ ) 'Usage Dim instance As New UploadStringCompletedEventHandler(AddressOf HandlerMethod)
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 Events and Delegates.
The following code example demonstrates asynchronously uploading a string.
Public Shared Sub UploadStringInBackground2(ByVal address As String) Dim client As WebClient = New WebClient() Dim data As String = "Time = 12:00am temperature = 50" AddHandler client.UploadStringCompleted, AddressOf UploadStringCallback2 Dim uri as Uri = New Uri(address) client.UploadStringAsync(uri, data) End Sub
void UploadStringInBackground2 (String* address)
{
WebClient* client = new WebClient ();
String* data = S"Time = 12:00am temperature = 50";
client->UploadStringCompleted += new UploadStringCompletedEventHandler (UploadStringCallback2);
client->UploadStringAsync (address, data);
}
The following method is called when the upload completes.
Private Shared Sub UploadStringCallback2(ByVal sender As Object, ByVal e As UploadStringCompletedEventArgs) Dim reply As String = CStr(e.Result) Console.WriteLine(reply) End Sub
void UploadStringCallback2 (Object* /*sender*/, UploadStringCompletedEventArgs* e)
{
String* reply = dynamic_cast<String*>(e->Result);
Console::WriteLine (reply);
}
