解释哪句呢？？

[tanxiangfeng]

解释 LPBYTE lpByte=(LPBYTE)GlobalLock(hBitmap); LPBITMAPINFOHEADER lpHeader=(LPBITMAPINFOHEADER)lpByte; 这两句，谢谢

[熙风]

  
LPBYTE lpByte=(LPBYTE)GlobalLock(hBitmap);   //分配内存;
LPBITMAPINFOHEADER lpBitmap = (LPBITMAPINFOHEADER)LockResource(hglb); ／／锁定资源

谢谢3楼大哥 LPBYTE lpByte=(LPBYTE)GlobalLock(hBitmap); LPBITMAPINFOHEADER lpHeader=(LPBITMAPINFOHEADER)lpByte; 我是想把这两句翻译成C#的代码是什么
