Question

I have a test method where I call an private function that converts a kind of to another kind.

This static function have the following signature:

private static Destiny[] Array2Array<Origin,Destiny> (Origin[] OriginVector)

Since it’s a private function, the tester give an error saying it cannot access it. So I got to this point:

Origin[] OriginVector = null; // TODO: Initialize to an appropriate value
Destiny[] expected = null; // TODO: Initialize to an appropriate value
Destiny[] actual;
var dummy = new ConversionClass();
var po = new PrivateObject( dummy, new PrivateType(typeof(ConversionClass)));
var acessor = new ConversionClassAcessor(po);

actual = po.Invoke("Array2Array", 
         new [] { typeof(Origin[]), typeof(Destiny[]) }, 
         new object[] { OriginVector } );

EDIT: That last line throws an compiler error with the message “cannot convert type object to Destiny[]”. What I’m doing wrong?

Answer 1

The answer is simple.. cast it. 😀

actual = (Destiny[]) po.Invoke("Array2Array", 
     new [] { typeof(Origin[]), typeof(Destiny[]) }, 
     new object[] { OriginVector } );
