工作学习 / 学科技术讨论 / c#dll里载入了一幅图像（Btye[] pBuffer）; c++主程序如何得到这个图像的地址？

c# interface: public int GetImageData(ref Byte[] pImageBuffer, ref UInt32 nImageWidth, ref UInt32 nImageHeight, ref UInt32 nImageBPP)

I guess image loaded (initiated) inside the function. then the interface should be public int GetImageData(out Byte[] pImageBuffer, ref UInt32 nImageWidth, ref UInt32 nImageHeight, ref UInt32 nImageBPP) . it will be exactly same as c++ interface.

BTW, in this way can c++ use cs's pImageBuffer directly ?

Yes, same way as using .NET FrameWork in C++.

在c++中如何把c#的 byte[] 转换到从c++的 byte× 中？

我曾经抄过一段代码：MemoryStream ms = new MemoryStream ();
int length=(int)ms.Length;
byte[] bytearr = ms.GetBuffer();
unsafe
{
fixed (byte* pSrc = bytearr)
{
int nTemp = *((int*)(pSrc+i) );
...
}
}
