Reading text from a file as blocks

Try this code.

            int n = 0;

            FileStream stream = File.Open(path, FileMode.Open, FileAccess.ReadWrite);
            StreamReader sr = new StreamReader(stream, Encoding.Default);

            StringCollection myStr = new StringCollection();

            string inputLine = "";
            while ((inputLine = sr.ReadLine()) != null)
            {
                myStr[n] += inputLine.Trim() + '\n';
                if (inputLine.Trim().Length > 0) n++;

            }
            txtbAusgabe.Text = myStr[0];

            sr.Close();
