As others pointed, you can use Reflection to do it, and Rick explains this perfectly in his papers. However, have in mind that in many cases you have other means to solve this. VFP developers are very accustomed to use this as it is easy and performs well enough in most cases, but non-VFP developers never had such a feature so readily available and didn't need it.

My recommendation would be to think about other approaches, and use dynamic code as a last resort. It is not only a performance issue. In many situations the performance impact is negliglible, but the problem is that you relax many many analysis features, as the ability to parse and refactor that code, leverage compiler checking, etc.
