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

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
