WPF: UnauthorizedAccessException using anonymous methods.
- by Diego Pacheco Pedemonte
Here is the thing, I want to create a simply app that copy many files from one site, and move them to another; but using async methods and create a new thread.
private void button3_Click(object sender, RoutedEventArgs e)
{
//progressBar1.Maximum = _FileInfoArray.Count;
DispatcherTimer dt1 = new DispatcherTimer();
foreach (FileInfo Fi in _FileInfoArray)
{
Thread t = new Thread(new ThreadStart(delegate()
{
DispatcherOperation _dispOp = progressBar1.Dispatcher.BeginInvoke(DispatcherPriority.Loaded, new Action(delegate()
{
File.Copy(txtdestino.Text, Fi.FullName, true);
//progressBar1.Value = n;
//txtstatus.Content = ("Copiados " + n.ToString() + " archivos");
//Thread.Sleep(100);
}
));
_dispOp.Completed += new EventHandler(_dispOp_Completed);
}
));
t.Start();
}
}
UnauthorizedAccessException is throw! It says that I can't access to txtdestino content. Some clues?
-------------------------------------------------------------------------------Edited
This is the version with all the changes, get the same error :( any clues?
private void button4_Click(object sender, RoutedEventArgs e)
{
//First: Build mynames
List<string> mynames = new List<string>();
foreach (FileInfo fi in _FileInfoArray)
{
mynames.Add(fi.FullName);
}
Thread t = new Thread(new ThreadStart(delegate()
{
foreach (string fullname in mynames)
{
DispatcherOperation _dispOp = progressBar1.Dispatcher.BeginInvoke(DispatcherPriority.Loaded, new Action(delegate()
{
string destino = System.IO.Path.Combine(@"C:\", System.IO.Path.GetFileName(fullname));
File.Copy(fullname, destino, true);
//Some progressbar changes
}
));
_dispOp.Completed += new EventHandler(_dispOp_Completed);
}
}
));
t.Start();
}
File.Copy(txtdestino.Text, Fi.FullName, true); // here the exception is throw
