ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString cannot return connection string

    Question

  • Hi,

    I want to use  ConfigurationManager to return my connection string, but I got an error "Object reference not set to an instance of an object."

    The code is

      return (string)System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

    My MyConnectionString is in the app.config saved in the same folder of cs file that issues the command.

    My application is WCF windows application. I am using vs2010.

    Thanks
