  Int Casting

  Dec 15, 2003 05:38 AM|LINK

  Hi all, atm I'm trying to do what I've got .. anyone know how I'm supposed to do this ...apart from splitting the string ?

  string test = "(1 + 2 + (65 * 2)) * 2";
  int formula = (int) test;
  int answer = formula;
  Response.Write(formula);

  it's not possible to calculate formulas by this way.... either you have to parse the arithmetic expression (but you don't want) or you use clientside scripting: JavaScript offers a powerful function named "eval" ...

  There are a couple ways of doing something like this. You can import the Excel Namespace and use the functions in Excel to caculate this. That may be an over kill. But it is probably the easiest way. The second way would be to use reflection. This can be tricky if you are not familure with reflection. The third is to use this app that I came across the other day. I don't know if it works but it would probably be your best bet. http://www.codeproject.com/dotnet/evaluator.asp If you need anything else just e-mail me.
