Instantiating a constructor with parameters in an internal class with reflection

Question

I have something along the lines of this:

object[] parameter = new object[1];
parameter[0] = x;
object instantiatedType =
Activator.CreateInstance(typeToInst         


        

Answer 1

(tested successfully)

object instantiatedType =
   Activator.CreateInstance(typeToInstantiate,
   System.Reflection.BindingFlags.NonPublic |
     System.Reflection.BindingFlags.Instance,
   null, new object[] {parameter}, null);

There are two issues this addresses:

• the new object[] {parameter} helps it handle the issue of passing an object[] as a single parameter of method that takes a params object[] argument
• the BindingFlags helps resolve the non-public constructor

(the two nulls relate to the binder; the default binder behaviour is fine for what we want)
