C# .NET 4.0 expression eval

Question

Possible Duplicates:
C# eval equivalent?
How can I evaluate a C# expression dynamically?

How can I evaluate a valid C# code and get results inside a compiled program (dynamically)? I know this is not very clear, i'll try to show that with a code snippet:

Visual C# 2010.

double x = 3.0;//this is function argument, we'll take 3
string str = "Math.Pow(x,2)+2*x+4";//value with written function in C#,equals: x^2+2x+4
double y = eval(str);
/* this is the idea! something like JS.I want to make string parsed into parameter,i.e
y=19 - this is what double y should became after eval(str) */

Hope you got the idea.

Thanks.

No, LINQ won't do this for you.

The closest you can easily get at the moment is to use CSharpCodeProvider which allows you to compile a whole assembly - but you'll need to wrap your expression in all the other source code required to make it a complete class.
