我得到一个转换异常

System.InvalidCastException：无法转换类型的对象System.Object的[]'输入'System.Object的[，]。 在Castle.Proxies.ITestProxy.Get2DArray（） 在Scratch.TestFixture.Get2DArray（）在TestTest.cs：17行

System.InvalidCastException : Unable to cast object of type 'System.Object[]' to type 'System.Object[,]'. at Castle.Proxies.ITestProxy.Get2DArray() at Scratch.TestFixture.Get2DArray() in TestTest.cs: line 17

从下面的：

[TestFixture]
public class TestFixture
{
    [Test]
    public void Get2DArray()
    {
        Substitute.For<ITest>().Get2DArray().Returns(new object[1,1]);
    }
}

public interface ITest
{
    object[,] Get2DArray();
}

任何人都可以抛出任何光线对此怎么看？我想这是一个 NSubstitute 错误？

推荐答案

NSubstitute取决于城堡，它依赖于Reflection.Emit的，所以他们指责Reflection.Emit的。

NSubstitute depends on Castle, which depends on Reflection.Emit, so they blame Reflection.Emit.

的解决方法，你的问题，看起来你无法使用多维数组。请注意，您的异常实际发生在 Get2DArray（），不是返回。

For a workaround to your problem, looks like you cannot use multidimensional arrays. Note that your exception actually occurs on Get2DArray(), not Returns.

请注意，我个人而言，我工作的一个嘲弄框架不使用Reflection.Emit的（也不城堡为此事），这将需要几个星期前，甚至是Alpha是准备好了，但它是一个相当强大的工具。在很多情况城堡失败，我不会（我的网站会列出这些）。如果您有兴趣，请按照 HTTP：//smug.$c$cplex.com

Please note that I, personally, am working on a mocking framework that does NOT use Reflection.Emit (nor Castle for that matter) It's going to take a few weeks before even an Alpha is ready, but it is quite a powerful tool. There are many scenarios Castle fails that I don't (my site will list these). If you are interested, please follow http://smug.codeplex.com
