Got to repo.

02. EventHandler

In the previouse chapter you have seen a way to read arguments by fetching them one by one.

This approach could be expensive especially when you have many argument as you my see the code in the prevouse chapter with many loops.

So maybe we want to execute a code especially when an argument is set.

This is what we are going to do using EventHandler.

using System.Collections.Generic;
using System.Linq;
using The_Morpher;

        static void Main(string[] args)
        {
            string commandLine = "start 5 3,6 true T --verbose --noClip --showStats -p driver=steave -p age=30 -c players=steave|john|clark -xc players=steave:21|john:15|clark:30";

            ECLP eCLP = new ECLP(commandLine);
            eCLP.AddedArgs += ECLP_AddedArgs;
            eCLP.AddedCollections += ECLP_AddedCollections;
            eCLP.AddedExCollections += ECLP_AddedExCollections;
            eCLP.AddedFlags += ECLP_AddedFlags;
            eCLP.AddedProperties += ECLP_AddedProperties;
            eCLP.Parse();

            Console.ReadKey();
        }

        private static void ECLP_AddedArgs(object sender, The_Morpher.Events.AddedArgsEvents e)
        {

        }

            // to do job when a specific property is triggered
            if (e.Property.Key == "driver")

            // to loop true sub values
            foreach (object o in e.Collections.Value)
            {
                Console.WriteLine("sub property is " + o + " and its type is " + o.GetType());

            // loop true the sub properties
            foreach (KeyValuePair sub in e.ExCollections.Value)
            {
                Console.WriteLine("sub property name is " + sub.Key + " and it's value is " + sub.Value + " and value type is " + sub.Value.GetType());
            }
        }
    }
