Dear all,

I want to execute mathematical expressions from file at runtime using .net FW 4.0, If any body can share the code, It will be very helpful.

Solution 1

If all you want to do is evaluate mathematical operations, then executing VB code is overkill. Have a look at this:
Math Parser .NET C#[^] You feed ita string, it returns the result.

While you can compile and execute VB code from within a program, it is a lot more complex to do, and a lot more dangerous (since it will have access to all the .NET methods, which is probably not what you want at all!)

Thanks a lot "OriginalGriff" :)
Your solution & suggestions are really nice & helpful, But in my requirement there will be equations like(Sorry i didn't mention) :-

a = add(5, 10) + subt(80, 40) ' Stored in text file

Where add() & subt() are(/has to be) defined in main program.
