Sort characters of a string in alphabetical order in C#

This article illustrates the different techniques to sort characters of a string in alphabetical order in C#.

We can use LINQ to sort characters of a string in alphabetical order in C#. The idea is to use LINQ’s OrderBy() method to create a sorted collection of all characters in the string, and then combine all characters together with the String.Concat() method.

using System;

using System.Linq;

public class Example

{

public static void Main()

{

String s = "SHdRVBAHskaBJSyHfD";

s = String.Concat(s.OrderBy(ch => ch));

Console.WriteLine(s); // ABBDHHHJRSSVadfksy

}

Another option is to convert the string to a character array and sort it, and then pass the sorted character array to the string constructor to get a sorted string instance. The following code example demonstrates this:

using System;

using System.Linq;

public static class StringExtensions

{

public static String Sort(this String input)

{

char[] chars = input.ToCharArray();

Array.Sort(chars);

return new String(chars);

}

public class Example

{

public static void Main()

{

String s = "SHdRVBAHskaBJSyHfD";

s = s.Sort();

Console.WriteLine(s); // ABBDHHHJRSSVadfksy

}
