VS环境下 C++版本：

1 int GetPreviewImage(const TCHAR* prtFile, const TCHAR* imageFile)
2 {
3 IStorage* pStorage = NULL;
4 HRESULT hResult = StgOpenStorage(prtFile, NULL, STGM_READ | STGM_SHARE_DENY_WRITE, NULL, 0, &pStorage);
5 if (hResult != S_OK)
6 {
7 return -1;
8 }
9
10 IStorage* pSubStorage = NULL;
11 hResult = pStorage->OpenStorage(_T("images"), NULL, STGM_READ | STGM_SHARE_EXCLUSIVE, NULL, 0, &pSubStorage);
12 if (hResult != S_OK)
13 {
14 return -1;
15 }
16
17 IStream *pStream = NULL;
18 hResult = pSubStorage->OpenStream( L"preview", NULL, STGM_READ | STGM_SHARE_EXCLUSIVE, 0, &pStream );
19 if (hResult != S_OK)
20 {
21 return -1;
22 }
23
24 const int nLen = 10*1024*1024;// 准备读入的长度
25 byte* image = new byte[nLen];
26 if (NULL == image)
27 {
28 return -1;
29 }
30
31 ULONG actRead;
32 pStream->Read(
33 image, // 存放放入的数据的缓冲区
34 nLen, // 要读入数据的长度，如不清楚可以设为较大的数
35 &actRead // 实际读入的长度
36 );
37
38 pStream->Release();
39 pStorage->Release();
40 pSubStorage->Release();
41
42 ofstream outfile(imageFile, ios::binary);
43 outfile.write((char*)image, actRead);
44 outfile.close();
45 delete image;
46 return 0;
47 }

业内还盛传一个C#版本，封装好了一个叫“ThumbnailCreator”的类，用法如下：

1 static void GetPartBmp(string sFileName)
2 {
3 string sOutputFileName = "";
4 if (!File.Exists(sFileName))
5 {
6 return;
7 }
8 sOutputFileName = sFileName.Substring(0, sFileName.LastIndexOf(".")) + ".bmp";
9 ThumbnailCreator thumbnail = new ThumbnailCreator();
10 Image img = thumbnail.GetThumbnail(sFileName);
11 if (img != null)
12 {
13 if (!File.Exists(sOutputFileName))
14 {
15 File.Delete(sOutputFileName);
16 }
17 img.Save(sOutputFileName, ImageFormat.Bmp);
18 }
19 }

ThumbnailCreator类实现：
