C# Linq ThenBy Method

Orders elements in a sequence using ThenBy() method.

We have the following string array.

string[] str = { "AAA", "AAAA", "A", "AAAAA", "AAAAAAAAA" };

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);

Example

using System;
using System.Linq;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      string[] str = { "AAA", "AAAA", "A", "AAAAA", "AAAAAAAAA" };
      IEnumerable<string> res = str.AsQueryable() .OrderBy(alp => alp.Length).ThenBy(alp => alp);
      foreach (string arr in res)
      Console.WriteLine(arr);
   }
}

Output

A
AAA
AAAA
AAAAA
AAAAAAAAA
