Gets the data that is downloaded by a DownloadDataAsync method.
Assembly: System (in System.dll)
You should check the Error and Cancelled properties before using the data that is returned by this property. If the Error property's value is an Exception object or the Cancelled property's value is true, the asynchronous operation did not complete correctly and the property's value will not be valid.
The following code example displays the value of this property.
Private Shared Sub DownloadDataCallback(ByVal sender As Object, ByVal e As DownloadDataCompletedEventArgs) Dim waiter As System.Threading.AutoResetEvent = CType(e.UserState, System.Threading.AutoResetEvent) Try ' If the request was not canceled and did not throw ' an exception, display the resource. If e.Cancelled = False AndAlso e.Error Is Nothing Then Dim data() As Byte = CType(e.Result, Byte()) Dim textData As String = System.Text.Encoding.UTF8.GetString(data) Console.WriteLine(textData) End If Finally ' Let the main application thread resume. waiter.Set() End Try End Sub
