VC.net 中语法如下.

 DWORD checksum1;
      unsigned char *rBuf;
      ....... 
      ..    {
        rBuf=new unsigned char[filelength];
        cfile.Read(rBuf,filelength);
        cfile.Close();
            for (i=0;i<filelength;i++)
            checksum1=checksum1+*(rBuf+i);
        delete rBuf;
    }

QUESTION:
1.如何将 *rBuf 改成VB.net语句?
