Private Object "Attempted to access a missing member" exception

Question

I am trying to invoke a private method of an object using private method. This method takes three arguments. Both signature of method i am trying to invoke and the code invoking this method are shown below

Signature of private method:

Public Class Foo
{
  private void SaveCallback(SaveAggregationViewResponse response,
                                         Action rollbackActionIfSaveFails,
                                         Action postSaveActionOnSuccess)
  {}
}

Code I am using to invoke method:

var foo=new Foo()
Private pFoo=new PrivateObject(foo);
var response=new SaveAggregationViewResponse();
pFoo.Invoke("SaveCallback",new object[]{response,(Action)null,(Action)null}); //this line throws exception

Exception Message: Method 'Foo.SaveCallback' not found.

Is there something wrong with the way I am invoking private method or some other setup is wrong?

Thank You

Answer 1

Try calling it with a ParamArray instead of an array of objects

pFoo.Invoke("SaveCallback",response,null,null);

Not sure whether to include the nulls, get rid of them if it doesn't work.
