在C＃和非托管C ++之间传递自定义对象

[英]Passing custom objects between C# and unmanaged C++

原文 2009-01-25 17:27:48 5 3 c#/ c++/ .net-2.0/ pinvoke/ unmanaged

I have a legacy DLL which contains a couple of methods I need to call from C# code. 我有一个旧版DLL，其中包含一些我需要从C＃代码调用的方法。 One of these methods takes in a pointer to another C++ class that lives within other C++ programs, not the DLL. 这些方法之一采用了指向其他C ++类（而不是DLL）中存在的另一个C ++类的指针。

I'm pretty sure I need to use pinvoke to marshal the objects back and forth, but I haven't found anything on marshaling custom objects. 我非常确定我需要使用pinvoke来回封送对象，但是在封送处理自定义对象时还没有发现任何东西。

What would be the best way of accomplishing this? 做到这一点的最佳方法是什么？

3 个解决方案

Are you sure it's a class and not a struct? 您确定这是一类而不是结构吗？ After all, different compilers could choose to lay the class out differently in memory which would break the target DLL. 毕竟，不同的编译器可能会选择将类放置在内存中的方式不同，这将破坏目标DLL。

Have you considered using a Managed C++ wrapper? 您是否考虑过使用托管C ++包装器？

我会看C ++ / CLI，尽管COM互操作可能会更容易，具体取决于C ++代码的形状。

如果只是几种方法使用Swig

在C＃库和C ++（CLR）之间传递对象 - Passing objects between C# library and C++ (CLR)

将数组从非托管 C++ 传递到 C# - Passing an array from unmanaged C++ to C#

将C＃结构传递给非托管C ++ DLL时出现SafeArrayTypeMismatchException - SafeArrayTypeMismatchException when passing c# struct to unmanaged C++ DLL

将C＃回调函数传递到托管和非托管C ++库中 - Passing a C# callback function into managed and unmanaged C++ libraries

非托管导出，将字符串数组从C ++传递到C＃ - Unmanaged Exports, passing an array of strings from C++ to C#

将struct从非托管C ++传递到C＃ - Passing struct from unmanaged C++ to C#

C＃-调用传递LPVARIANT的非托管C ++函数 - C# - Calling unmanaged C++ function passing LPVARIANT

从C ++非托管DLL传递C＃函数 - Passing C# function from C++ unmanaged dll

将向量/数组从非托管C ++传递到C＃ - Passing a vector/array from unmanaged C++ to C#

将指向class的指针传递给C＃中的非托管c ++代码 - Passing a pointer to class into unmanaged c++ code from C#
