random guessing game

Question

This is a windows form application in C#
i have a higher/lower guessing game that is complete but i did not read the question carefully.
the question asks to allow users to keep guessing until thy guess the number. chooses two colors for your game: one should be used to indicate that the value the users guessed is higher than the target; the other is used to indicate that the value the users guessed is lower than the target. with each new guess, change the form color based on whether the guess is higher than the target or lower. keep count of the number of guess. when they hit the target, display a message box indicating the number of guesses it took.
my program only lets the user enter 3 tries, i have no color for the text and my message box says something like "You have won! Would you like to play again ?"
making this program was very difficult for me to make so i would like some help making these corrections.
Thankyou
