Program to Check Whether a String Palindrome is or not

If you're looking to explore a detailed explanation of the Palindrome program in C#, check out the following resource: https://www.c-sharpcorner.com/article/explaining-palindrome-program-in-c-sharp/

None of these codes are efficient as mine :p Static bool isPalindrome(string s) { for (int i = 0; i < s.Length / 2; i++) { if (s[i] != s[s.Length - 1 - i]) return false; } return true; }

Before comparing string convert it to upper or lower then it will work for both 'Malayalam'.as its not working for this string like if (revs.ToLower()==s.ToLower()) in the above example

Using System;using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication1 { public class Palindrome { static void Main() { string str = "Aba", rev = ""; foreach (char c in str) { rev = c+rev; } if(str.Equals(rev,StringComparison.OrdinalIgnoreCase)) Console.WriteLine("String is Palindrome"); else Console.WriteLine("String is not Palindrome"); Console.ReadKey(); } } }

Thanks nice explanation ..........................

String GetValue = txtBody.Text(); string ReturnStr = GetValue.SequenceEqual(GetValue .Reverse());

string strVal = "Malayalam".ToLower(); char[] alpha = strVal.ToCharArray(); int i = 0; int strlen = strVal.Length; for ( i = 0; i <= alpha.Length-1; i++) {string FirstVal = alpha.GetValue(i).ToString(); string LastVal = alpha.GetValue(strlen-1).ToString(); if (FirstVal == LastVal){strlen = strlen - 1;} else {Console.WriteLine("this is Not pallindrome");return;} }

Thank u

Here is my code without using any for loops:using System;public class Test{ public static void Main() { string s=Console.ReadLine(); char[] rev=s.ToCharArray(); Array.Reverse(rev); string revs=new string(rev); if(s.Equals(revs)) Console.WriteLine("Palindrome"); else Console.WriteLine("Not Palindrome"); } }

Can any one help me to make a program in c# to find out number of palindrome substring in a string

It works only for Case sensitive string.Like according to above Program 'Malayalam' is Not Palindrome while 'malayalam' is Palindrome.

Here is more efficient code for checking palindrome string public static bool palindrome(string str) { if (str.Length < 2) return false; for (int i = 0, len = str.Length - 1; i < str.Length / 2; i , len--) { if (str[i] == '.') i ;// This code is to ignore . if (str[len] == '.') len--;//this code is to ignore . if (str[i] != str[len]) return false; } return true; }
