No in my Application, i can upload only a file of type *.txt or *.csv,

so could u tell me how can i display a message to the user, when he is uploading a file of (.txt or .csv)type only when that particular file is open in his machine..

As of now in my application, it makes the application crash if that uploading file is open in user machine..

please check my code here..

private void BtnBrowseClick(object sender, RoutedEventArgs e)
        {
            OpenFileDialog file1 = new OpenFileDialog { Multiselect = false, Filter = "All Supported Files |*.txt;*.csv|Text|*.txt|CSV |*.csv"};
            if (file1.ShowDialog() == true)
            {
                new FileInfo(file1.FileName);
                try
                {
                    using (Stream str = file1.OpenFile())
                    {
                        TextReader reader = new StreamReader(str);
                        reader.ReadToEnd();
                        txtFileName.Text = file1.FileName;
                        txtFileName.IsEnabled = false;

                    }
                }
                catch
                {
                    txtFileName.Text = file1.FileName;
                    txtFileName.IsEnabled = false;
                    MessageBox.Show("Please check the file has been Closed before you upload", "LRM..! Manual Feed File Upload");
                }
            }
        }


It is showing warning message if i change the security of that file,but it i think that is not a right way..
So could u tell me the solution, if it needed ignore my code and tell me with a new sample of code..
