@Padmanabhan, Venkatesh You will need to add System.Configuration assembly reference to access configuration settings, using ConfigurationManager. To add the reference, just right click References and click to add references. In C# application you can use the following code:

var applicationSettings = ConfigurationManager.GetSection("TestSIS") as NameValueCollection; // for reading MatchMMDS replace TestSIS to MatchMMDS

    if (applicationSettings.Count == 0)
    {
        Console.WriteLine("Application Settings are not defined");
    }
    else
    {
        foreach (var key in applicationSettings.AllKeys)
        {
            Console.WriteLine(key + " = " + applicationSettings[key]);
        }
    }
