So I'm trying to learn more about lambda expressions. I read this question on stackoverflow, concurred with the chosen answer, and have attempted to implement the algorithm using a console app in C# using a simple LINQ expression.

My question is: how do I translate the "var result" of the lambda expression into a usable object that I can then print the result?

I would also appreciate an in-depth explanation of what is happening when I declare the outer => outer.Value.Frequency

(I've read numerous explanations of lambda expressions but additional clarification would help)

C#
//Input : {5, 13, 6, 5, 13, 7, 8, 6, 5}

//Output : {5, 5, 5, 13, 13, 6, 6, 7, 8}

//The question is to arrange the numbers in the array in decreasing order of their frequency, preserving the order of their occurrence.

//If there is a tie, like in this example between 13 and 6, then the number occurring first in the input array would come first in the output array.

      List<int> input = new List<int>();
      input.Add(5);
      input.Add(13);
      input.Add(6);
      input.Add(5);
      input.Add(13);
      input.Add(7);
      input.Add(8);
      input.Add(6);
      input.Add(5);      

      Dictionary<int, FrequencyAndValue> dictionary = new Dictionary<int, FrequencyAndValue>();

      foreach (int number in input)
      {
        if (!dictionary.ContainsKey(number))
        {
          dictionary.Add(number, new FrequencyAndValue(1, number) );
        }
        else
        {
          dictionary[number].Frequency++;
        }
      }

      var result = dictionary.OrderByDescending(outer => outer.Value.Frequency);

      // How to translate the result into something I can print??
