No, not at all. It’s a wrapper for a normal dictionary, the keys that I use are just so its easy to track through the demo. Take my code and give it a shot. You could just as well call

_dictionary.Add(“some-key”, “some value”);
string someVar = _dictionary["some-key"]

Heck, you could even use this as an extension method to a normal IDictionary

public dynamic Get(this IDictionary dictionary, string key) {
return dictionary[key];
}
var d = new Dictionary();
d["string-key"] = “a string”;
d["float-key"] = 123.03f;
string s = d.Get(“string-key”);
float f = d.Get(“float-key”);
