使用PrivateObject.Invoke调用静态转换函数不能在C#中编译 [英] Using PrivateObject.Invoke to call a static conversion function do not compile in C#

问题描述

我有一个测试方法，我在其中调用一个私有函数，该函数将一种转换为另一种.

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

此静态函数具有以下签名:

This static function have the following signature:

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

由于它是私有函数，因此测试仪会给出一个错误消息，表明它无法访问它.所以我到了这一点:

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 } );

最后一行引发编译器错误，并显示消息无法将类型对象转换为Destiny []".我在做什么错了?

That last line throws an compiler error with the message "cannot convert type object to Destiny[]". What I'm doing wrong?

推荐答案

答案很简单. :D

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