Select Random String From An Array In .NET Core and C#

How to select a random string from an array of strings

 

This article demonstrates how to pick a random string an array of strings.

 

We can use the random number generator to pick a random item from an array. The following code snippet has an array of author names (strings). We can pick a random author by generating a random number that is less than the number of items in the array and use the random index to pick a random author name in the string.

 

The Random.Next method generates a random integer and by passing the maximum length of the array means the random number cannot be greater than the number of items in the array. 

using System;
public class RandomStringInArraySample
{
public static void Main()
{
// A array of authors
string[] authors = { "Mahesh Chand", "Jeff Prosise", "Dave McCarter", "Allen O'neill",
"Monica Rathbun", "Henry He", "Raj Kumar", "Mark Prime",
"Rose Tracey", "Mike Crown" };

// Create a Random object
Random rand = new Random();
// Generate a random index less than the size of the array.
int index = rand.Next(authors.Length);
// Display the result.
Console.WriteLine($"Randomly selected author is {authors[index]}");

Console.ReadKey();
}
}
