Instances of this class are passed to the UploadStringCompletedEventHandler.

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

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
