How to convert my PHP code to C# dimensional array

I have a data from database, that I want to put into an array for later process.

php version:

$data = [];
// $data[date][id] = [name, age];
$data["09/10/2023"][10] = ['name' => 'John Smith', 'age' => 50];
$data["09/10/2023"][11] = ['name' => 'Amie Kim', 'age' => 30];

How can I write the above code in C# ?
Later I want to loop through that data.

>Solution :

Use a C# Dictionary to hold Person objects:

// Define a class to hold the name and age
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

// Then in your method or constructor
var data = new Dictionary<string, Dictionary<int, Person>>();

// Initialize the inner dictionary for the date "09/10/2023"
data["09/10/2023"] = new Dictionary<int, Person>();

// Add the persons
data["09/10/2023"][10] = new Person { Name = "John Smith", Age = 50 };
data["09/10/2023"][11] = new Person { Name = "Amie Kim", Age = 30 };
