C# program to check if a string is palindrome or not
To check if a string is palindrome or not, you need to first find the reverse of the string using −
Array.reverse()
After that use the equals() method to match the original string with the reversed. If the result is true, that would mean the string is Palindrome.
Example
Let us try the complete example. Here, our string is “Malayalam”, which is when reversed gives the same result.
using System;
namespace palindromecheck {
class Program {
static void Main(string[] args) {
string string1, rev;
string1 = "Malayalam";
char[] ch = string1.ToCharArray();
Array.Reverse(ch);
rev = new string(ch);
bool b = string1.Equals(rev, StringComparison.OrdinalIgnoreCase);
if (b == true) {
Console.WriteLine("" + string1 + " is a Palindrome!");
} else {
Console.WriteLine(" " + string1 + " is not a Palindrome!");
}
Console.Read();
}
}
}Output
Malayalam is a Palindrome!
