Last update on December 20 2024 12:51:39 (UTC/GMT +8 hours)

Write a program in C# Sharp to split a collection of strings into some groups.

Sample Solution:

C# Sharp Code:

using System;
using System.Linq;
using System.Collections.Generic;

class LinqExercise29
{
    static void Main(string[] args)
    {
        // Array of cities
        string[] cities =
        {
            "ROME","LONDON","NAIROBI","CALIFORNIA",
            "ZURICH","NEW DELHI","AMSTERDAM",
            "ABU DHABI", "PARIS","NEW YORK"
        };

        // Displaying the instruction for the operation
        Console.Write("\nLINQ : Split a collection of strings into some groups  : ");
        Console.Write("\n-------------------------------------------------------\n");
        Console.Write("\nThe cities are : 'ROME','LONDON','NAIROBI','CALIFORNIA','ZURICH','NEW DELHI', \n");
        Console.Write("                   'AMSTERDAM','ABU DHABI','PARIS','NEW YORK' \n");
        Console.Write("\nHere is the group of cities : \n\n");

        // Using LINQ to split the array of cities into groups of three
        var citySplit = from i in Enumerable.Range(0, cities.Length)
                        group cities[i] by i / 3;

        // Iterating through each group of cities and displaying them using the cityView method
        foreach (var city in citySplit)
        {
            // Calling cityView method to display each group of cities
            cityView(string.Join(";  ", city.ToArray()));
        }

        Console.ReadLine(); // Wait for user input before closing the console
    }

    // Method to display a group of cities
    static void cityView(string cityMetro)
    {
        Console.WriteLine(cityMetro); // Displaying the group of cities
        Console.WriteLine("-- here is a group of cities --\n"); // Additional separator
    }
}

Sample Output:

LINQ : Split a collection of strings into some groups  :                                                      
-------------------------------------------------------                                                       
    
The cities are : 'ROME','LONDON','NAIROBI','CALIFORNIA','ZURICH','NEW DELHI',                                 
                   'AMSTERDAM','ABU DHABI','PARIS','NEW YORK'                                                 
   
Here is the group of cities :                                                                                 
ROME;  LONDON;  NAIROBI                                                                                       
-- here is a group of cities -- 
                                                                             
CALIFORNIA;  ZURICH;  NEW DELHI                                                                               
-- here is a group of cities --  
                                                                              
AMSTERDAM;  ABU DHABI;  PARIS                                

-- here is a group of cities -- 
                                                                              
NEW YORK
