One Dimensional Array in C#

In this chapter you will learn:

• What is single dimensional array?
• How to declare one dimensional array?
• How to use single dimensional array in C# programming?

The one dimensional array or single dimensional array in C# is the simplest type of array that contains only one row for storing data. It has single set of square bracket (“[]”). To declare single dimensional array in C#, you can write the following code.

string[] Books = new string[5];

Programming Example of One Dimensional Array:

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

namespace One_Dimensional_Array
{
    class Program
    {
        static void Main(string[] args)
        {
            //Declaring single dimensional array
            string[] Books = new string[5];
            Books[0] = "C#";
            Books[1] = "Java";
            Books[2] = "VB.NET";
            Books[3] = "C++";
            Books[4] = "C";

            Console.WriteLine("All the element of Books array is:\n\n");

            int i = 0;
            //Formatting Output
            Console.Write("\t1\t2\t3\t4\t5\n\n\t");
            for (i = 0; i < 5; i++)
            {
                Console.Write("{0}\t", Books[i]);
            }
            Console.ReadLine();
        }
    }
}

Output

All the element of Books array is:



1       2        3              4        5


C#    Java    VB.NET    C++    C
