C# app.config format issue

Question

Hello everyone,

If the app.config format is wrong, for example, not a correct format XML file, application will fail from loading. Are there any ways to let me know such issue -- for example, receiving some events (so that I could write file log and event log to record this issue) if app.config loads error because of a mal-formatted XML file?

thanks in advance, George

My code and app.config looks like this, but no exception is thrown.

    class Program
    {
        public static void MyEventHandler(object sender, EventArgs e)
        {
            return;
        }

        static void Main(string[] args)
        {
            AppDomain currentDomain = AppDomain.CurrentDomain;
            currentDomain.UnhandledException += MyEventHandler;

            return;
        }
    }

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configuration>

Within your application start up, e.g. within a static constructor of the main class. you can define it as

  AppDomain currentDomain = AppDomain.CurrentDomain;
  currentDomain.UnhandledException += MyHandler; // define MyHanlder somewhere.

to catch the ConfigurationErrorsException due to the config.
