Hi everyone,
I am developing a WinForms application and I need a Math Expression
validator, not an expression evaluator. So I want to be able to say...

if ((sales - tax) > 20)
THEN (x * y * 0.55)

without knowing at runtime what the values of sales, tax, x and y are. Is
there any software out there that will do this validation for me?

Thanks in advance

If, at runtime, you have variables sales, tax, x and y, you can obtain their values exactly as your sample code has done.

Why is it that the following code does not support your needs?

if ((sales - tax) > 20)
return x * y * 0.55;
