Hi
i am new to c sharp. i am building a simple calculator with a text box and few buttons. i need to store values entered into the text box from string to char array so that i can check for the '+' and perform addition among the elements like 12+22+11. i need to add all this functionality to the = button because i'll be using the + button to just add data into the textbox like 1, 2 buttons etc. This is what i have in the = button
