using System;
using System.IO;

            using (StreamReader sr = new StreamReader(path))

                     string [] split = s.Split(';');

                     //now loop through split array
                     //split[0] is server

        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }

What are you trying to achieve? Read connection string from text file? Why would you want to do that?

Actually if you are working with Asp.Net, you must store your connection strings in web.config and read it through WebConfigurationManager and if you working in desktop then a similar file named app.config exists.

You must store your connection strings in these xml files rather than storing it in text file and trying to parse it. Hope it helps you.
