Question

 string stringValue = "1+2+3";

How can I convert the above string value with operators, "1+2+3", so that it can be assigned to the intvalue as shown below in C#.

 int intValue = 1+2+3;

i.e intValue = 6;

You could compile it with `Microsoft.CSharp.CSharpCodeProvider` of course... — Niels Keurentjes, May 31 '13 at 15:58
Lol that's actually the answer there. My god, what happened to good old stack based processing of a simple mathematical expression? — Niels Keurentjes, May 31 '13 at 15:59
Please try harder to research instead of asking these redundant questions. It's easier to google than to type all those stuff you've typed. — aiapatag, May 31 '13 at 16:07
Define "operators"? Do you want to work with just base 10 integers? — Jodrell, May 31 '13 at 16:07

You need to compile on the fly. See for example Evaluate C# Code or Flee.

I have used this library in many projects: C# calculation engine

It's very simple to use:

var ce = new CalcEngine();
double result = (double)ce.Evaluate("1+2+3");
