(轉)CString轉爲unsigned char

1）CString轉unsigned char *：

   CString str("abcd");
   unsigned char *source = (unsigned char*)str.GetBuffer(0);

2）CString轉unsigned char數組：

    CString str("abcd");
    unsigned char source[1024] = {0};
    memcpy(source, (unsigned char *)str.GetBuffer(0), str.GetLength() * 2);

3）打印source

   for (int i = 0; i < str.GetLength(); i ++)
   {
      printf("%c", source[i]);
   }
