How to read connection string from web.config in non-web application

In this example, I will use console application but you can use Winform or WCF.


static void Main(string[] args)


  System.Configuration.Configuration cf = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(“/IPMS_RMTR”);

  System.Configuration.ConnectionStringSettings connsetting;


  connsetting = cf.ConnectionStrings.ConnectionStrings[“IPMSConnectionString”];




The key part here is, many developers might not get what is “/IPMS_RMTR”. /IPMS_RTMR is the web application that you configure in your IIS 7, see picture below.




Source code ConAppReadWebConfig.rar is available in my skydrive.
