  • 12 years ago

    using System;
    using System.Collections.Generic;
    using System.Text;
    using System.Configuration;

    namespace ConsoleApplication111
        class Program
            static void Main(string[] args)

                String s = ConfigurationManager.AppSettings["Test"];
                Int32 foo = Int32.Parse(s);
    <?xml version="1.0" encoding="utf-8" ?>
            <add key="Test" value="12"/>

     with this code I get a
    Unhandled Exception: System.ArgumentNullException: Value cannot be null, Error. The name of the file is appconfig and it is in the same directory as the executable...
