C# Program to order array elements

Use ThenBy() method to order array elements. Let’s say we have the following string array.

string[] str = { "Sandler", "Jack", "Tom", "Matt", "Henry", "Johnny" };

Now, use Lambda Expressions and set a condition inside the ThenBy() method to sort the strings according to the number of characters they have.

IEnumerable<string> res = str.AsQueryable().OrderBy(alp => alp.Length).ThenBy(alp => alp);

Here is the entire example to order array elements using ThenBy() method.

Example

 Live Demo

using System; using System.Linq; using System.Collections.Generic; public class Demo {    public static void Main() {       string[] str = { "Sandler", "Jack", "Tom", "Matt", "Henry", "Johnny" };       IEnumerable<string> res = str.AsQueryable().OrderBy(alp => alp.Length).ThenBy(alp => alp);       foreach (string arr in res)       Console.WriteLine(arr);    } }

Output

Tom Jack Matt Henry Johnny Sandler
