How to evaluate expression. Maybe like:

int a=1;
int b=3;
int c=Eval("a+b");

or

int c=int.parse("1+3*(2+3)");

This seems stupid to me. is it possible in c#?

Answer 1

You can take code, and using the CSharpCodeProvider write an Eval function that actually compiles your code into an in-memory assembly and then executes that code.

See this CodeProject article for sample source.
