答
HGLOBAL hMem = GlobalAlloc(GMEM_MOVEABLE, dataSize);
LPVOID pImage = GlobalLock(hMem);
memcpy(pImage, pngData, dataSize);
GlobalUnlock(hMem);
ATL::CComPtr<IStream> pStream;
CreateStreamOnHGlobal(hMem, TRUE, &pStream);
Gdiplus::Bitmap *pBitmap = new Gdiplus::Bitmap(pStream);
HICON YOUR_HICON = pBitmap->GetHICON();
