How to rewrite a statement "WordCount[word] += 1;"?

Is it "WordCount[word] = WordCount.key + 1;"?

LexicalAnalysis.cs 
using System.Collections.Generic;

namespace Treehouse.CodeChallenges
{
    public class LexicalAnalysis
    {
        public Dictionary<string, int> WordCount = new Dictionary<string, int>();


        public void AddWord(string word)
        {
           if(WordCount.ContainsKey(word))
           {
             WordCount[word] +=  1;
           }
           else 
           {
               WordCount.Add(word, 0);
               WordCount[word] += 1;

           }


        }
    }
}

This code should pass task 1 as it is. But if you want to make it more compact, when you add a new word you can give it the value "1" at the same time and then skip the increment:

           else 
           {
               WordCount.Add(word, 1);
           }
