64到32位的互操作 - 如何？ [英] 64 to 32 bit Interop - how?

问题描述

我需要整合一些旧的32位code - 要我没有源$ C ​​$ C，到项目以这样一种方式，它可以从64位.NET被称为部件。原来的code为实现为在一个DLL 32位COM对象。 Windows不允许直接调用从64到32位的对象，所以我在寻找灵感就如何处理这种情况。

I need to integrate some legacy 32-bit code - for which I don't have the source code, into a project in such a way that it can be called from a 64-bit .NET assembly. The original code is implemented as a 32-bit COM object in a DLL. Windows doesn't allow direct calls from 64 to 32-bit objects, so I'm looking for inspiration on how to deal with this situation.

如何才能传统的32位COM对象可以从64位.NET程序集访问？

How can a legacy 32-bit COM object be accessed from a 64-bit .NET assembly?

更新：我们发现，COM组件本身周围的一些ANSI C，这是我们founf原始源的包装。我们能够编译在Visual Studio作为一个原生的64位DLL，并导入到.NET - ！不好意思移动球门柱

UPDATE: We discovered that the COM component was itself a wrapper around some ANSI C, which we founf the original source for. We were able to compile that in Visual Studio as a native 64-bit dll, and import that into .NET - sorry to move the goalposts!

推荐答案

最好的办法是使出来，它包装的32位DLL进程内COM服务器。然后，您可以从64位code调用此。

The best approach is to make an out of process COM server that wraps your 32-bit DLL. You can then call this from 64bit code.

这是基本概念的解释。
