How to use Dictionary in Unity?

Question

C++ / C#

I'm making a store in my game. I found out that there is such a thing as a Dictionary, looked at how it's all done and wrote the following code in the unit:

var Сell = new Dictionary<string, int>(){
      { "Skin1" : 0},
};

But for some reason Visual Studio highlights this code in red. Why and how to solve it?

Answer 1

Because a syntax error. Specifically, a colon.
And because you must first learn the language, and then climb into the unit.

Answer 2

You have a syntax error here

var Сell = new Dictionary<string, int>(){
      { "Skin1" : 0}, // Вот здесь
};

It should be like this:

var cell = new Dictionary<string, int>() {
    { "Skin1", 0 },
};

Either like this:

var cell = new Dictionary<string, int>() {
    ["Skin1"] = 0,
};
