How to update value of a key in dictionary in c#?
c#, c#-4.0, dictionary, key-value
Solution
Have you tried just
dictionary["cat"] = 5;
:)
Update
dictionary["cat"] = 5+2;
dictionary["cat"] = dictionary["cat"]+2;
dictionary["cat"] += 2;
Beware of non-existing keys :)
Problem
I have the following code in c# , basically it's a simple dictionary with some keys and their values. ``` Dictionary<string, int> dictionary = new Dictionary<string, int>(); dictionary.Add("cat", 2); dictionary.Add("dog", 1); dictionary.Add("llama", 0); dictionary.Add("iguana", -1); ``` I want to update the key 'cat' with new value 5. How could I do this?
