How to use C# Array

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 :
[csharp] using System; [/csharp]


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 :
[csharp] 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; } } } [/csharp]

Output :

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

Output :

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

Output :

Display :
[csharp] 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]); } } [/csharp]

Output :
