How to iterate over a C# dictionary?

Firstly, add elements −

IDictionary<int, int> d = new Dictionary<int, int>();
d.Add(1,97);
d.Add(2,89);
d.Add(3,77);
d.Add(4,88);

Now, get the keys −

List<int> myList = new List<int>(d.Keys);

To iterate −

foreach (int k in myList) {
   Console.WriteLine("{0}, {1}", k, d[k]);
}

The following is an example −

Example

 Live Demo

using System;
using System.Collections.Generic;

public class Demo {
   public static void Main() {
      IDictionary < int, int > d = new Dictionary < int, int > ();
      d.Add(1, 97);
      d.Add(2, 89);
      d.Add(3, 77);
      d.Add(4, 88);

      List < int > myList = new List < int > (d.Keys);
   
      foreach(int k in myList) {
         Console.WriteLine("{0}, {1}", k, d[k]);
      }
   }
}

Output

1, 97
2, 89
3, 77
4, 88
