How to pull the key value based on the key that is inside the Dictionary?

Question

Let's say I did the following:

Dictionary<string,NetworkStream> dictionary = new Dictionary<string,NetworkStream>();
dictionary.add("Matt",network);
dictionary.add("Mike",network);
dictionary.add("Jack",network);

How do I pull the Networkstream of Jack? Assuming I have multiple of lines likes this.

UPDATE: I didn't explain myself well, sorry. If the name is already exists I'm not going to add him to the dictionary.. I meant if I have different names.

it is not possible that you have multiple lines containing the key "Jack" - you'd get `key already exists exception`. To retrieve by key: `dictionary["Jack"]` — Gilad Green, Nov 24 '16 at 18:19
Multiple lines of what? You can't have more than one "Jack" as a key. Dictionary keys are unique — SteelSoul, Nov 24 '16 at 18:19
@NateS that's still unclear ; if you have different name of what ? — Sehnsucht, Nov 24 '16 at 18:25
@NateS after you updated the question, Sajeetharan's answer is correct. You should try and learn how to use a class before trying to use it :) — SteelSoul, Nov 24 '16 at 18:25

Dictionary cannot have more than one key with same name, still you can access the value of 'Jack' like this,

value = dictionary["Jack"];

@NateS if you are updating keys with different names, above solution should work – Sajeetharan Nov 24 '16 at 18:26
