将托管内存传递给"void **参数"；在托管的C ++代码中 [英] passsing managed memory to "void** argument" in managed c++ code

问题描述

嗨
我有一个托管的c ++类，我使用的主要函数实现了void **参数. void **参数指向2d字节数组，每次调用后都会对其进行大量修改，但不幸的是，该函数经常被调用.

您建议在什么情况下传递可以由托管c ++函数直接修改的C#变量?

亲切的问候.
Ali

Hi
I have a manged c++ class which the main function I use implements a void** parameter. void** parameter points to a 2d array of bytes which is modified a lot after each function call and unfortunately the function is called frequently.

What scenario do you propose to pass a C# variable which can be directly modified by the managed c++ function?

Kind Regards.
Ali

推荐答案

如果将数组的地址传递给C ++类，则只要数组包含基本类型，它就可以直接访问数组中的信息.

If you pass the address of the array to the C++ class then it can directly access the information in the array, as long as the array contains basic types rather than C# class objects.

我什么都没提议.您有问题吗?

I don''t propose anything. Do you have a question?

我的意思是我不需要直接代码.是否有任何建议，如果是您的问题，您将如何处理?

预先感谢

Hi,

I mean I do not need direct code. Any suggestion that if it is your problem how would you approach it?

Thanks in advance
