您可以使用从C ++到C#转换器的演示版进行一次最多2000行的文件夹转换和一次最多200行的代码段转换.

Hi Hellexx,

You can use the Demo Edition of C++ to C# Converter for folder conversions up to 2000 lines and code snippet conversions up to 200 lines at a time.

您是否尝试过GlobalAlloc()或GlobalHandle ()?

do you have tried GlobalAlloc() or GlobalHandle()?

IntPtr可以引用C ++的常规指针，无论它是什么:void *，int *，long *，float *，等等.
如果您要调用返回指针的C ++函数或需要引用的指针参数，请

您肯定像您编写的那样在C#代码中需要IntPtr.

IntPtr can refer to a conventional pointer of C++, whatever it is : void*, int*, long*, float*, so on.

If you are gonna call a C++ function which returns a pointer or need a referenced pointer parameter,

you surely needs IntPtr in your C# code like you wrote.
