How to generate an instance of an unknown type at runtime?

Question

i've got the following in C#:

string typename = "System.Int32";
string value = "4";

theses two strings should be taken to generate an object of the specified type with the specified value...

result should be:

object o = CreateUnknownType(typename, value);
...
Int32 test = (Int32)o;

Answer 1

Is this what are you are thinking?

object result = Convert.ChangeType("4", Type.GetType("System.Int32"));
