Run Script Files From C# And Listen For Output

Hello, is it possible to run sql script files from c# and listen to messages?

foreach (string aScript in scripts)
{
if (File.Exists(aScript))
{
txtProgress.Text += Environment.NewLine + " Run script: " + aScript + " - Start time: " + DateTime.Now.ToString() + Environment.NewLine;

__streamReader = new StreamReader(aScript);
__myQuery = __streamReader.ReadToEnd();
__cmd.CommandType = CommandType.Text;
__cmd.CommandText = __myQuery;
__cmd.CommandTimeout = 5000000;
__rc = __cmd.ExecuteNonQuery();
txtProgreso.Text += Enviroment.NewLine; // MESSAGE HERE
__streamReader.Close();
}
}

I tried with
// Create a SqlNotificationRequest object.
SqlNotificationRequest notficationRequest = new SqlNotificationRequest();

// Associate the notification request with the command.
__cmd.Notification = notficationRequest;

But I get an error saying I need SQL 9 or later, aldo SQL 2005 Express says it´s version 9

Is there another way?
Thanks!
