I want to calculate all the number of characters I have used in a textbox.
For example: If I write this equation in textbox:
so what code or line should I write for counting all the parenthesis used here?
var strEquation=textbox1.Text; //5x-2(3y+2)*3y(8)
int x = strEquation.Count(c => Char.IsNumber(c)); // 6 int y = strEquation.Count(c => Char.IsLetter(c)); // 3 int total=x+y;
Let me know if it works?
