How do I create a Dictionary that holds different types in C#

Question

I need some sort of way to store key/value pairs where the value can be of different types.

So I like to do:

 int i = 12;
 string s = \"test\";
 doub         


        

Answer 1

You could declare a Dictionary containing just the type object and then cast your results; .e.g.

Dictionary storage = new Dictionary();

storage.Add("age", 12);
storage.Add("name", "test");
storage.Add("bmi", 24.1);

int a = (int)storage["age"];
string b = (string)storage["name"];
double c = (double)storage["bmi"];

However, this isn't that elegant. If you know you are always going to be storing age, name, bmi I would create an object to encapsulate those and store that instead. E.g.

public class PersonInfo
{
    public int Age { get; set; }
    public string Name { get; set; }
    public double Bmi { get; set; }
}

And then use that insead of the Dictionary... e.g.

PersonInfo person1 = new PersonInfo { Name = "test", Age = 32, Bmi = 25.01 };

int age = person1.Age;

etc.
