C# Sharp Exercises: Reverse the case of all characters of given string

C# Sharp String: Exercise-48 with Solution

Write a C# Sharp program to reverse the case (upper->lower, lower->upper) of all the characters of given string.

Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;
namespace exercises
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Original string: PHP");
            Console.WriteLine("After reversing the case of all characters of the said string: " + test("PHP"));
            Console.WriteLine("\nOriginal string: JavaScript");
            Console.WriteLine("After reversing the case of all characters of the said string: " + test("JavaScript"));
            Console.WriteLine("\nOriginal string: Python 3.0");
            Console.WriteLine("After reversing the case of all characters of the said string: " + test("Python 3.0"));

        }
        public static string test(string text)
        {
            return string.Concat(text.Select(x => char.IsUpper(x) ? char.ToLower(x) : char.ToUpper(x)));
        }
    }
}

Sample Output:

Original string: PHP
After reversing the case of all characters of the said string: php

Original string: JavaScript
After reversing the case of all characters of the said string: jAVAsCRIPT

Original string: Python 3.0
After reversing the case of all characters of the said string: pYTHON 3.0

Previous: Write a C# Sharp program to find the length of the longest substring without repeating characters from a given string.
Next: Write a C# Sharp program to find the middle character(s) of a given string. Return the middle character if the length of the string is odd and return two middle characters if the length of the string is even.
