C# – How to Print a Dictionary

This post shows you how to print a Dictionary object in C#. We will need to do this when we want to print the data of the Dictionary object to View, or even print data to Output window of Visual Studio for debugging purposes, etc.

Let’s consider the below code.

using System;
using System.Collections.Generic;

namespace ByteNota
{
    class Program
    {
        static void Main(string[] args)
        {
            Dictionary<string, int> animalAges = new Dictionary<string, int>();
            animalAges.Add("Lion", 35);
            animalAges.Add("Elephant", 70);
            animalAges.Add("Rabbit", 9);
            animalAges.Add("Macaw", 50);
            animalAges.Add("Fox", 14);

            // print the dictionary to console
            string output = "";
            foreach (KeyValuePair<string, int> kvp in animalAges)
            {
                output += string.Format("Name = {0}, Age = {1}", kvp.Key, kvp.Value);
                output += "\n";
            }
            Console.WriteLine(output);
        }
    }
}

In the above code, we define a sample animalAges Dictionary object, iterate through the object and print the data out to Console window.

Output:

Name = Lion, Age = 35
Name = Elephant, Age = 70
Name = Rabbit, Age = 9
Name = Macaw, Age = 50
Name = Fox, Age = 14
