c# - Increase Value of Dictionary at a specified Key -

I have a bool variable and a dictionary if this is true, then I will use a special key The price will have to increase.

My code:

  Private zero process (person) {SendMailSuccessful = true; If (SendMailSuccessful) {MyDictionary.Where (i = & gt; i.Key == person.personID); // I have to increase the value of that ID from 1}}    
 
 
 Why are you Using the LINQ picture, and not just the indicator of the dictionary?  
 Something like this  
  MyDictionary [person.personID] + = 1;
