c++ - 视觉 C++ : how to pass pointer to array as parameter?

Question

下面显示的代码是用Visual C++编写的

array<Byte>^ b = gcnew array <Byte> (filesize);
fs->Read(b,0,b->Length);
unsigned char *pb;
pb=(byte*)malloc(b->Length);    //pb is unmanaged here.

for(int i=0;i<b->Length;i++)
{
     *(pb+i)=InverseByte(b+i);
}

我想调用下面的函数来反转每个字节。我怎样才能做到这一点？我想对托管数组 b 的每个字节进行逆运算，并将其放入非托管数组 b。

unsigned char InverseByte(unsigned char* PbByte)
{
    //something;
}

Answer 1

修复InverseByte的声明:

unsigned char InverseByte(unsigned char value)

所以你可以像这样使用它:

for (int i=0; i < b->Length; i++)
{
    pb[i] = InverseByte(b[i]);
}
