Adding two numbers in the same string

Question

Hi there

I had this typed out and clicked "post" and all i got was a cleared post screen, so forgive me if i forget something

Basically i need an answer to a string similar to "2+3" or "9+6/3"

The only way i can see to do this in to seperate the two terms and operation, and then "if (Operation == "+") FirstInt + SecondInt" and so on.

Is there a way to make C# run what is contained in the string as a sort of command?

Thanks in advance.

Hmm To be honest i'm just starting out with C# and that sort of thing is way over my head. What i'm writing is a program that generates a question like those strings in my first post and then finds the answer. Is there an easier way to do that? (generate 2 integers and save them as variables then somehow substitute an operation in there somewhere?) Im not so sure =\

Unless something has been sneaked into v3.5 that I've missed C# doesn't have an 'eval' function but it's possible to build your own using a combination of JScript and CodeDom. See the article below which features some improvements to some earlier code which is also linked to: http://www.egilh.com/blog/archive/2006/10/02/3062.aspx Don't forget to add a reference to Microsoft.JScript (on the .NET tab) to your project in order for this to compile and work.

Ya we are testing the forums and looks like something is not working right. We will try to fix it as soon as we find out what is going on here.
