Question

I have a class Referrals. When you create an object in the class, it checks that the input strings are unique (and therefore never allows duplicate objects). But when I find that input string str1 is equal to that of a previously created object, instead of creating a new object or just returning false, i want to change a property of the already created object. But i can’t figure out how to do this, as the method has no way of knowing the name of the object. But I know something unique about it! I feel like this must be enough to somehow call it, and do what I need to do.

Any ideas?
THANKS!

Here is the class:

public class Referral
{
    public class Referral
    {
        public string URL;
        public Dictionary<string, int> Keywords = new Dictionary<string, int>();

        private static Dictionary<string, string> URLs = new Dictionary<string, string>();
        private int HowManyURLs;
        private bool UniqueURL;
        private bool UniqueKeyword;

        public Referral(string MyURL, string MyKeyword, int MyOccurrences)   //Constructor
        {
    if (HowManyURLs == 0)
    {
        URL = MyURL;
        Keywords.Add(MyKeyword, MyOccurrences);
        URLs.Add(MyURL, MyKeyword);
        HowManyURLs++;
    }

    else
    {
        // RESET FLAGS
        UniqueURL = true;
        UniqueKeyword = true;

        for ( int i = 0; i < HowManyURLs; i++ )
        {
        if ( URLs.ContainsKey( MyURL ) )
        {
            // TRIP URL FLAG
            UniqueURL = false;

            // NOW CHECK KEYWORDS OF URL << THIS IS WHAT I CAN'T DO!
            if ( URLs.ContainsKey( MyKeyword ) )
            {
            // TRIP KEYWORD FLAG
            UniqueKeyword = false;

             // ADD TO OCCURRENCES
    //      Referral[MyURL].Occurrences += MyOccurrences;
            }
        }
        }

    // IF BOTH FLAGS TRUE
    if  ( UniqueURL == true && UniqueKeyword == true )
    {
        URL = MyURL;
        Keywords.Add(MyKeyword, MyOccurrences);
        URLs.Add(MyURL, MyKeyword);
        HowManyURLs++;
    }

    }

        }
    }

Why don’t you create a List of Referral objects outside of the Referral object itself? That way you can check the List to see if the object with your criteria already exists. If so, update that object. If not, create a new one and add it to the list.

Either that or use a static list, also declared outside of the Referrals class.

I’m not 100% sure where you’re going with this, so hopefully one of those approaches will work for you.
