Question

I’ve been handed a Byte[] that contains a file. I need to pass this to another method that is expecting two parameters, a char* to the beginning of the file and a char* to the end of the file.

I’m assuming I need to pin the array first so it doesn’t get collected. I don’t imagine I can then just cast the first and last elements, right?

Old question, but I just found out that you can create a pin_ptr<unsigned char> from such an array and then reinterpret_cast the result.

    pin_ptr<unsigned char> pinned = &buffer[0];
    unsigned char* unsignedBufferPtr = pinned;
    char* bufferPtr = reinterpret_cast<char*>(unsignedBufferPtr);

You can then use a reinterpret_cast on the result
