You might can get the connection string and then split it into an array like below:

using System.Configuration;

string s = ConfigurationManager.ConnectionStrings["aspnetdbConnectionString"].ConnectionString;
        string[] arr = s.Split(';');
        Dictionary<string, string> keypairs = new Dictionary<string, string>();
        foreach (string st in arr)
        {
            string[] kp = st.Split('=');
            if (kp.Length > 1)
            {
                keypairs.Add(kp[0], kp[1]);
            }
        }
       string servername = keypairs["Data Source"]; //access the items using the keys

Note: There should be an easy way but this was what I came up with

If you are working with SQL server you may find the SqlConnectionStringBuilder Class helpful.

The following is the msdn doco with example

Hope that helps
