title: Convert string into mathematical expression
body: <p>I'm trying to convert a text from textbox in a WinForms. I have an application which is drawing charts from linear equation (fe x^2+2x+3) and I need to have output in mathematical expression to make it work. </p>
  
  <p>Main problem I'm facing is I can't find way to convert string "Math.pow(x,2)" to (I don't know if I'm doing this correct) dynamic answer = Math.pow(x,2); </p>
  
  <p>Can you please help me? </p>
