Palindrome in C# GUI

You can enter any word, number, sentence(without punctuation marks) and this will give the output yes or no.



//my palindrome code
//please enter the input sentence without any symbols like ,.? etc

            //So that everything in lower case

            //RaCeCar is same as RaceCar
            string low = textBox1.Text.ToLower()
            //so that panlindrome sentence can also be chaecked

                    button1.Text = "Try Again";
                    textBox1.Focus()
                    //so that the application does not get closed after braking the loop and u can try again
                    //this is used in the if statement after breaking the loop
                    i = 2;
                    break;
                }
            }
            if (i < 2)
            {
                label1.Visible = true;
                label1.Text = "It is a Palindrome";
                button1.Text = "Try Another";
                textBox1.Focus();
            }
            else
            {
                //the value is reset to 0
                //or else the application will get stucked
                i = 0;
            }
        }
    }
}

uses array ,first index and last index 

this is the one and only GUI version of palindrome available on-line  checking word and sentences
