int size = Mat.total() * Mat.elemSize();
byte * bytes = new byte[size];
std::memcpy(bytes, Mat.data, size * sizeof(byte));

// convert native byte array to managed Byte array
array<Byte> ^byteArray = gcnew array<Byte>(size + 2);
Marshal::Copy((IntPtr)bytes, byteArray, 0, size);

You can do it this way:

char buf[] = "Native String";
int len = strlen(buf);
array<Byte> ^byteArray = gcnew array<Byte>(len + 2);
Marshal::Copy( (IntPtr)buf, byteArray, 0, len );

You can find some more info in this MSDN article.
