c# - Extract key value pair from dictionary

Question

I'm at the first step in programming and i'm stuck with a problem with Dictionary(key value) pair. The statement of the problem is:

Write a console application that extracts and prints the key and value on a line. Example: For input data: year:2018

The console will display:

year

2018

here is my code:

        string inputData = Console.ReadLine();
        Dictionary<string, int> dictionary = new Dictionary<string, int>();
        dictionary.Add(inputData, 2018 );

        foreach (KeyValuePair<string, int> kvp in dictionary)
        {
            Console.WriteLine("{0}
{1}", kvp.Key, kvp.Value);
        }

question from:https://stackoverflow.com/questions/65617458/extract-key-value-pair-from-dictionary

Answer 1

// expects year:2018
var inputData = Console.ReadLine();

// split by ':' to get 'year' and '2018' values
var values = inputData.Split(':');

// creates a dictionary
var dictionary = new Dictionary<string, int>();

// add the 'year' string as key and '2018' as value
dictionary.Add(values[0], Convert.ToInt32(values[1]));

// print all the dictionary
foreach (var kvp in dictionary)
{
    Console.WriteLine("{0}
{1}", kvp.Key, kvp.Value);
}

However, the problem description is not asking you to use a dictionary. So, instead of creating a dictionary, you can simply print the values.

var inputData = Console.ReadLine();
var values = inputData.Split(':');
Console.WriteLine(values[0]);
Console.WriteLine(values[1]);
