使用OpenFileDialog C＃WPF将PDF复制到其他文件夹

Question

I tried complete my program, with this code:

private void btnBuscar_Click(object sender, RoutedEventArgs e)
        {
            FileInfo f = null;
            OpenFileDialog dlg;
            dlg = new OpenFileDialog();
            dlg.Filter = "Document Files (*.doc;*pdf)|*.doc;*pdf";
            dlg.InitialDirectory = Environment.SpecialFolder.UserProfile.ToString();
            dlg.Title = "Seleccione su archivo de cotización.";
            //Open the Pop-Up Window to select the file
            bool? result = dlg.ShowDialog();
            if (result == true)
            {
                f = new FileInfo(dlg.FileName,);
                using (Stream s = dlg.OpenFile())
                {
                    TextReader reader = new StreamReader(s);
                    string st = reader.ReadToEnd();
                    txtPath.Text = dlg.FileName;
                }
                File.Copy(dlg.FileName,@"C:\Formatos\m1");
            }

        }

The problem is when select the file with OpenFileDialog the program Crash automatically. I need copy the files only, and save the path of the copy file in the DB.

Thank you for you help!

Change bool? result = dlg.ShowDialog(); bool? result = dlg.ShowDialog(); to if (dlg.ShowDialog() == DialogResult.OK)

Also, remove the extra comma from f = new FileInfo(dlg.FileName,);
