Getting the sum of random values from Dictionary

Question

Hello all!

Coding C# question here!

I have inventory with 4 different objects: Lemon, Apple, Coffee, Mango

each object has different score: 20, 40, 60, 80 (respectively).

I want to use dictionary to assign the values. Dictionary<string, float> scoreDictionary = new Dictionary<string, float>()

Now whenever I see only apple, Lemon and Mango (or other combination), I want the method to sum their values

So my plane is to add each value to dictionary and then be able to sum the values based on the Key I get.

      if ((rows[0].stoppedSlot != rows[1].stoppedSlot) && (rows[1].stoppedSlot != rows[2].stoppedSlot))
     {
         for (int i = 0; i < prizeDictionary.Count; i++)
         {
             // here summarize the three values I get
         }
     }

So basically, in other script I assign a string and add it's name + value to a dictionary,

and in the other script I want to say, "take the strings that you get" and sum the values based on the string name.

So I take it you want to add the values of the other three items. Something like this might work, feed the function a string name, the loop goes through each key and compares, adds to the score IF the key doesn't match.

     int FindSum (string thisItem)
     {
         int totalScore = 0;
         foreach (string k in scoreDictionary.Keys)
         {
             if (k != thisItem)
             {
                 totalScore += scoreDictionary[k];
             }
         }
         return totalScore;
     }
