Dictionary Csharp

Example

using System;
using System.Collections.Generic;

Dictionary<string, int> ages = new Dictionary<string, int>();

// fill the Dictionary
ages.Add("John", 51);    // using the Add method
ages.Add("Diana", 50);
ages["James"] = 23;      // using array notation
ages["Francesca"] = 21;

// iterate using a foreach statement
// the iterator generates a KeyValuePair item
Console.WriteLine("The Dictionary contains:");

foreach (KeyValuePair<string, int> element in ages)
{
    string name = element.Key;
    int age = element.Value;
    Console.WriteLine($"Name: {name}, Age: {age}");
}
