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