KeyValuePair in C#

The KeyValuePair class stores a pair of values in a single list with C#.

Set KeyValuePair and add elements −

var myList = new List<KeyValuePair<string, int>>();

// adding elements
myList.Add(new KeyValuePair<string, int>("Laptop", 20));
myList.Add(new KeyValuePair<string, int>("Desktop", 40));
myList.Add(new KeyValuePair<string, int>("Tablet", 60));

Here is the code to learn how to work with KeyValuePair and display the keys and values −

Example

Using System;
using System.Collections.Generic;
class Program {
   static void Main() {
      var myList = new List<KeyValuePair<string, int>>();
      // adding elements
      myList.Add(new KeyValuePair<string, int>("Laptop", 20));
      myList.Add(new KeyValuePair<string, int>("Desktop", 40));
      myList.Add(new KeyValuePair<string, int>("Tablet", 60));
      foreach (var val in myList) {
         Console.WriteLine(val);
      }
   }
}
