The following is our Dictionary with some elements −

Dictionary<int, string> d = new Dictionary<int, string>() {
   {1,"Electronics"},
   {2, "Clothing"},
   {3,"Toys"},
   {4,"Footwear"},
   {5, "Accessories"}
};

Now to display the first element, set the key like this.

d[1];

The above displays the first element.

Example

using System;
using System.Collections.Generic;
public class Program {
   public static void Main() {
      Dictionary<int, string> d = new Dictionary<int, string>() {
         {1,"Electronics"},
         {2, "Clothing"},
         {3,"Toys"},
         {4,"Footwear"},
         {5, "Accessories"}
      };
      foreach (KeyValuePair<int, string> ele in d) {
         Console.WriteLine("Key = {0}, Value = {1}", ele.Key, ele.Value);
      }
      Console.WriteLine("First element: "+d[1]);
   }
}

Output

Key = 1, Value = Electronics
Key = 2, Value = Clothing
Key = 3, Value = Toys
Key = 4, Value = Footwear
Key = 5, Value = Accessories
First element: Electronics
