How to use C# Array

Description :

Hi Friends, let me give you a intro about “Array”. It stores a fixed-size sequential collection of elements of the same type. And its indexes start at zero. Arrays are declared much like variables, with a set of [] brackets after the datatype. 

 

Namespace :


using System;

 

Step1 :

Please open visual studio, right now i have visual studio 2013 i just opened my visual studio and click on new project.

Step2 :

In the new project window please click on templates visual c# and then click on windows  and on the right side panel just click on console application. Please give a name for the console application and click ok button.

Step3 :

If you see the visual studio will gives you a predefined template program  for us.

Step4 :

Lets, Build simple console application to Find Count, Sort and  Display items from List.

Main Method :


public static string[] stringArray = new string[5] { "A", "C", "B", "E", "D" };
 public static Boolean flag = true;
 static void Main(string[] args)
 {
 while (flag)
 {
 Console.WriteLine("\n1. Lenght \t\t2. Sort \n3. Display\t\t4. Exit");
 Console.Write("Please enter your Choice: ");
 string choice = Console.ReadLine();
 switch (choice)
 {
 case "1":
 Length(stringArray);
 break;
 case "2":
 Sort(stringArray);
 break;
 case "3":
 Display(stringArray);
 break;
 case "4":
 flag = false;
 break;
 default:
 Console.WriteLine("Enter correct choice !!");
 break;
 }
 }
 }

Output :

Length :


private static void Length(string[] stringArray)
 {
 int count = stringArray.Length;
 Console.WriteLine("Count of Array : " + count);
 }

Output :

Sort :


private static void Sort(string[] stringArray)
 {
 Array.Sort(stringArray);
 Display(stringArray);
 }

Output :

Display :


private static void Display(string[] stringArray)
 {
 Console.WriteLine("Items in Array : ");
 for (int i = 0; i < stringArray.Length; i++)
 {
 Console.WriteLine("Index " + i + "\t: " + stringArray[i]);
 }
 }

Output :
