Hi Experts

I have a rather research type of question for which I googled a lot but could not find any solution. May be anybody here can throw a some light on this.

In a website solution with app.config in a class library project and web.config in website project, is it possible that the class library project can directly use the connection string from web.config ? If yes, then what are the probable solutions ?

there isn't any direct solution for this, but you can use a web service in your web application that get the web.config connection strings.

XML

namespace test
{
    /// <summary>
    /// Summary description for WebService1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    // [System.Web.Script.Services.ScriptService]
    public class WebService1 : System.Web.Services.WebService
    {

        [WebMethod]
        public List<string> Conns()
        {
            var items = System.Configuration.ConfigurationManager.ConnectionStrings.Cast<string>().ToList();
            return items;
        }
    }
}

this web service return all connections in a list!
this is a base for you, go ahead and read online resources for help and if you have question about this ask again!
