How to create class at runtime from file

Question

Is it possible to create a class at runtime from a file without parsing it?

If not what would be the best approach to retrieve class properties, constructors and methods from a file? Taking into account that a file could have more than one class just like a typical cs file.

What does this question have to-do with regex? Also duplicate of this question: http://stackoverflow.com/questions/826398/is-it-possible-to-dynamically-compile-and-execute-c-code-fragments — Simeon Pilgrim, Nov 19 '09 at 22:53

If you are using ASP.NET take a look at BuildManager.GetCompiledAssembly.

Here's an example usage:

Assembly a = BuildManager.GetCompiledAssembly("~/TestClass.cs");
foreach (Type t in a.GetExportedTypes()) {
    object obj = Activator.CreateInstance(t)
    // Do something with obj...
}
