Activator.CreateInstance with private sealed class

Question

I\'m trying to new up a LocalCommand instance which is a private class of System.Data.SqlClient.SqlCommandSet. I seem to be able to grab the type information just fine:

I might be a little late in responding, but I ran into a similar problem that fits into this topic.
I wanted to instantiate a non public constructor using Activator.CreateInstance and passing it arguments.

public class Node
{
    string name;
    Node parent;

    protected Node(string name,Node parent)
    {
       this.name = name;
       this.parent = parent;
    }

    public static Node Create(string name,Node parent)
    {
       Node result = Activator.CreateInstance(
         type: typeof(Node),
         bindingAttr: BindingFlags.Instance  | BindingFlags.NonPublic,
         binder: null, //default binder
         args: new object[] { name, parent },
         culture: null);
       return (Node)result;
    }
}

The tricky part was the binding flags.

My first instinct was to use BindingFlags.CreateInstance | BindingFlags.NonPublic, however that caused an exception to be thrown: MissingMethodException Constructor on type 'Node' not found.
