Class name as a string variable

[ADi]

Hello,

I'm wondering it is possible somehow in C# to make that operation
possible:

abstract class ParentClass { };
class ClassA : ParentClass { };
class ClassB : ParentClass { };
class ClassC : ParentClass { };

ParentClass object; // declare an abstract object

string[] Classes = new String[] { "ClassA", "ClassB", "ClassC" };

object = new Classes[0](); // defining "ClassA" object
^^^^^^^^^^

....in other words, how to make object which name is given as string
variable? It's possible AT ALL?

You have to use reflection. Check out System.Reflection namespace. And also,
just do a search on Google. You will find tons of sample code.

I think you're looking for Activator.CreateInstance and possibly
Type.GetType as well.

Thnx for the clue, System.Reflection is exactly what I need...

thanks again
