[C#] Adding Event Listener to static void Main() fails, why?

Hi All,

Trying to download some strings from a webpage, then fires an event for each download that completes. However, when trying to add the event listener, the program throws the following error:

An object reference is required for the non-static field, method, or property 'Test.Program.client_OpenReadCompleted(object, System.Net.OpenReadCompletedEventArgs)'

Code is here: http://codepad.org/mAZVd4DJ

The line with the error is line 22.

How can I get around this?

Please let me know if you require more information, thanks!

Just pull the work into a non-static method.

Code:

---

class Program
{
        static void Main( string [ ] args )
        {
            var program = new Program();

            program.ProcessConnections( );
        }

        public void ProcessConnections()
        {
            List<string> dataList = new List<string>( );

            for ( int index = 0; index < 5; index++ )
            {
                try
                {
                    WebClient client = new WebClient( );
                    client.OpenReadCompleted += Client_OpenReadCompleted;
                    Stream stream = client.OpenRead( new Uri( "http://graph.facebook.com/347971448616743/photos?limit=30&offset=" + index * 10 ) );

                    StreamReader streamReader = new StreamReader( stream );
                    dataList.Add( streamReader.ReadToEnd( ) );
                }
                catch ( WebException webException )
                {
                    Console.WriteLine( webException.Message );
                }
            }

            Console.WriteLine( "Finished downloading, showing results..." );

            foreach ( string data in dataList )
            {
                Console.WriteLine( data.Substring( 0, 50 ) );
            }

            Console.ReadLine( );


        }

        public void Client_OpenReadCompleted( object sender, OpenReadCompletedEventArgs e )
        {
            Console.WriteLine( "Finished a download" );        }
}

Perfect, thank you very much!
