How to use TryGetValue with Dictionary to test and get value if exists in one statement
The TryGetValue method of Dictionary allows you to test if a key exists in the dictionary and if so, return the value, which makes for code that reads nicely.
using System;
using System.Collections.Generic;

namespace TestDictionary882282
{
    class Program
    {
        static void Main(string[] args)
        {
            Dictionary<int, string> variableNames = new Dictionary<int, string>();

            variableNames.Add(3, "first");
            variableNames.Add(7, "second");
            variableNames.Add(21, "third");
            variableNames.Add(22, "fourth");
            variableNames.Add(24, "fifth");

            int[] keys = { 3, 7, 22, 23, 24, 25 };

            string variableName = "";
            foreach (var key in keys)
            {
                if(variableNames.TryGetValue(key, out variableName))
                    Console.WriteLine("key {0} equals {1}", key, variableName);
                else
                    Console.WriteLine("KEY {0} DOES NOT EXIST", key);
            }

            Console.ReadLine();
        }
    }
}
