C# Palindrome Stack not working

Question

i would like your help with my program. I'm trying to check if the user input is a palindrome. This is my code.

        Stack cstack = new Stack();
        Stack rstack = new Stack();
        Console.WriteLine("Enter a palindrome string");
        string input = Console.ReadLine();

        foreach (char c in input)
        {
            cstack.Push(c);
        }

        foreach (var v in cstack)
        {
            rstack.Push(v);
        }

        if (cstack.Equals(rstack))
        {
            Console.Write("String is a palindrome");
        }
        else
        {
            Console.Write("String is not a palindrome");
        }

        Console.ReadLine();

So what i hope my code is doing is getting input from the user. Pushing the user input as characters into the cstack using a foreach loop. Reversing the characters in the cstack (Which should hold the users input) into a new stack called rstack using another foreach loop. Then using an if else statement which will check to see if the c stack which holds the original input is equal to the reverse stack. This comparison will determine if the string is a palindrome.

Cheers everyone for the help. I'm glad i didn't come out as an idiot with no clue as to what he was doing.

Sorry guys but would anyone know how to make it so the palindrome ignores case sensitivity. I assume you convert the string into lowercase with the ToLower, but really i have no idea I've never needed a string to be case insensitive before.

Stack<char> cstack = new Stack<char>();
            string input = "PoP";

            var inputToUpper = input.ToUpper(); /*assuming case senstivity is not to be considered */

            foreach (char c in inputToUpper)
            {
                cstack.Push(c);
            }

            bool isPalindrome = true;
            var noOfItems = cstack.Count;

            for(int i=0; i< noOfItems ; i++)
            {
                if (inputToUpper[i] != cstack.Pop())
                {
                    isPalindrome = false; break;
                }
            }

            if (isPalindrome)
            {
                Console.WriteLine("Palindrome");
            }
            else
            {
                Console.WriteLine("Non Palindrome");
            }
