In this video we will discuss how to reverse each word in a string using c#. This is a common c# interview question.

Reverse the following string
one two three four five

Output should be
eno owt eerht ruof evif

Here is the C# code that can do this
string inputString = “one two three four five”;
string resultString = string.Join(” “, inputString
.Split(‘ ‘)
.Select(x =] new String(x.Reverse().ToArray())));

Console.WriteLine(resultString);

Make sure you have the following using declarations
using System;
using System.Linq;

Here is what is happening with the above code
Split the input string using a single space as the separator. Split() method returns a string array that contains each word of the input string.
Select method, constructs a new string array, by reversing each character in each word.
Join method converts the string array into a string.
