互操作的自动化错误 [英] Automation error with interop

问题描述

我最近不得不重建为从VB6调用而创建的C＃互操作。我已经用regasm注册了它（使用代码库开关），并将tlb添加为对VB6项目的引用，但是当我尝试调用它时，出现以下自动化错误：-2146232832（0x80131600）

I have recently had to rebuild a C# interop created for calling from VB6. I have registered it with regasm (using codebase switch) and added the tlb as a reference to the VB6 project but when I attempt to call it I get the following automation error: -2146232832 (0x80131600)

如果我以完全相同的方式注册现有的interop dll并将其添加到我的项目中，则可以正常工作。我能想到的唯一区别是该项目从VS8升级到了VS9（虽然是相同的.net版本），并且我现在正在64位计算机上编译（我知道这是有问题的）。我将项目设置为x86，但是仍然出现自动化错误。

If I register the existing interop dll in exactly the same way and add to my project, it works fine. The only differences I can think of are that the project has since been upgraded from VS8 to VS9 (same .net version though), and I'm now compiling on a 64-bit machine (which I know there are issues around this). I have set the project to compile as x86 but I still get the automation error.

任何想法？

推荐答案

您的C＃代码引发了异常，没有被捕获。具体来说就是ApplicationException。这是框架代码永远不会抛出的异常，它必须位于您的C＃源代码中。

Your C# code is throwing an exception and it isn't being caught. Specifically an ApplicationException. That's an exception that the framework code never throws, it must be located in your C# source code.

如果找不到该代码，则需要调试代码。问题。使用项目+属性的调试选项卡来执行此操作。选择启动外部程序，然后将其指向c：\program files\microsoft visual studio\vb98\vb6.exe。然后，单击调试+异常，选中 CLR异常的抛出复选框。

You'll need to debug the code if you can't locate the problem. Do so with Project + Properties, Debug tab. Select "Start external program" and point it to c:\program files\microsoft visual studio\vb98\vb6.exe. Then Debug + Exceptions, tick the Thrown checkbox for CLR exceptions.

现在可以按F5键，VB6 IDE开始运行。加载您的VB6项目并重现该问题。调试器在引发异常的C＃代码行处停止。

You can now press F5 and the VB6 IDE start running. Load your VB6 project and reproduce the problem. The debugger stops at the line of C# code that throws the exception.
