Parsing a C# string statement and executing it via reflection to get a value

Is there a utility that can take a C# string like this:

'Utils.ComputeValue('Myval1', 'Myval2');'

And execute the underlying function via reflection and return a value?

I can parse and trigger via reflection myself, but am trying to avoid that.

The idea is also to restrict ability to call functions into one specific namespace... to avoid abuse.
