1. using System;
2. using System.Collections.Generic;
3. class GFG {
4. // Driver code
5. public static void Main()
6. {
7. // Create a new dictionary
8. // of strings, with string keys.
9. Dictionary<string, string> myDict =
10. new Dictionary<string, string>();
11. // Adding key/value pairs in myDict
12. myDict.Add("Australia", "Canberra");
13. myDict.Add("Belgium", "Brussels");
14. myDict.Add("Netherlands", "Amsterdam");
15. myDict.Add("China", "Beijing");
16. myDict.Add("Russia", "Moscow");
17. myDict.Add("India", "New Delhi");
18. // To get count of key/value
19. // pairs in myDict
20. Console.WriteLine("Total key/value pairs in"+
21. " myDict are : " + myDict.Count);
22. // Displaying the key/value
23. // pairs in myDict
24. Console.WriteLine("The key/value pairs"+
25. " in myDict are : ");
26. foreach(KeyValuePair<string, string> kvp in myDict)
27. {
28. Console.WriteLine("Key = {0}, Value = {1}",
29. kvp.Key, kvp.Value);
30. }
31. }
32. }
Output:

Total key/value pairs in myDict are : 6
The key/value pairs in myDict are :
Key = Australia, Value = Canberra
Key = Belgium, Value = Brussels
Key = Netherlands, Value = Amsterdam
Key = China, Value = Beijing
Key = Russia, Value = Moscow
