Coldfusion 实例化 .Net 引用时缺少错误信息

Question

所以我正在使用 Microsoft Office Open XML SDK，并尝试在我的 CF 10 实例中实例化它的类。

我开始尝试创建一个DocumentType 类，所以我使用了代码：

writeDump(createObject("dotnet","DocumentFormat.OpenXml.Wordprocessing.DocumentType","C:\Program Files (x86)\Open XML SDK\V2.5\lib\DocumentFormat.OpenXml.dll").DocumentType());abort;

不过，这给了我一个错误，没有有用的信息。

然后我读到您还需要在类信息中包含命名空间。然而，这也会导致错误，但有一些不错的信息：

在指定的程序集列表中找不到类 DocumentFormat.OpenXml.Wordprocessing.DocumentFormat.OpenXml.Wordprocessing.DocumentType。

必须将包含该类的程序集提供给程序集属性。

我现在对此有些困惑。我是不是在做一些明显的错误。

作为第二点，有没有办法转储 DLL 包含的所有我可以引用的类？

编辑

按照 cmets 中@Leigh 的建议将代码更改为：

writeDump(createObject("dotnet","DocumentFormat.OpenXml.Wordprocessing.DocumentType","C:\Program Files (x86)\Open XML SDK\V2.5\lib\DocumentFormat.OpenXml.dll"));abort;

在：C:\ColdFusion10\cfusion\jnbridge\error.log 中产生此错误

Answer 1

我以前遇到过这个问题。发生的情况是 .Net 代码返回了一个没有代理的类，或者抛出了 jnbridge/CF .Net 没有代理的 SomeClass.CustomException 类型的异常。在这两种情况下都返回“ClassNotFound”。

我所做的是提前将这些类添加到程序集列表中并实例化，然后转储它们（这样就构建了类代理）。
