在C#中调用C ++函数 [英] calling c++ function in c#

问题描述

您好，下面是代码示例.请建议我该怎么做才能将c ++编写的函数调用为c#函数.
预先谢谢你
C ++代码

Hi following is the code example. Please suggest what should I do to call c++ written function to a c# function.
Thank you in advance
c++ code

// type defs. for Graphic Gemms Code - see later

#define BYTE_IMAGE

#ifdef BYTE_IMAGE
typedef unsigned char kz_pixel_t;        /* for 8 bit-per-pixel images */
#define uiNR_OF_GREY (256)
#else
typedef unsigned short kz_pixel_t;       /* for 12 bit-per-pixel images (default) */
# define uiNR_OF_GREY (4096)
#endif
static int CLAHE (kz_pixel_t* pImage, unsigned int uiXRes, unsigned int uiYRes,
         kz_pixel_t Min, kz_pixel_t Max, unsigned int uiNrX, unsigned int uiNrY,
              unsigned int uiNrBins, float fCliplimit)
 {
...
...
}

C#调用代码

c# calling code

csharpfunction()
{
CLAHE((byte*)im, 0, 0, 0, 0, 0, 0, 0, 0.02);
}

我是图像实例. C ++代码获取字节格式的指针.如何将引用转换为我的图像对象以将函数作为字节*传递.

im is image instance. the c++ code gets the pointer in byte formate. how can I convert the referece to my image object to pass in the function as byte*.
Please help will be very thankful to you.

推荐答案

据我了解，您需要使用C ++代码创建一个程序集，然后使用以下代码:

http://msdn.microsoft.com/en-us/library/aa984739％28v = vs.71％29.aspx [ ^ ]

我不是100％知道这一点，但是在使用Windows DLL时，这就是我的工作.

From what I understand, you need to create an assembly with you C++ code and then use the following:

http://msdn.microsoft.com/en-us/library/aa984739%28v=vs.71%29.aspx[^]

Im not 100% sure of this, but when using the Windows DLLs thats what I do.

您可以做的是....
创建一个c ++代码的程序集，然后
通过在C#代码中实现属性在C#中使用它...

尝试使用DLLImport，然后提供已创建的DLL的名称，然后在C#代码中以这种方式引用该dll文件....

快乐编码...

What you can do is ....
Create a assembly of the c++ code and then
use it in C# by implementing Attributes in your C# code...

Try using DLLImport and then give the name of the DLL that you have created and then refer to that dll file this way in your C# code....

Happy Coding...

如果图像是位图，请使用msdn.microsoft.com/en-us/library/5ey6h79d.aspx只需将IntPtr替换为字节*.

If image is a bitmap use msdn.microsoft.com/en-us/library/5ey6h79d.aspx just replace IntPtr wíth byte*.
