那么，您如何期望SQLServer的PDF存储文件可以作为图像检索呢?
您需要一个转换器将PDF转换为图像，然后显示它.
看看这些:
PDF到Image Converter SDK的VB.NET示例 [如何使用Ghostscript API将PDF转换为图像 [
Well, how can you expect that PDF stored file from SQLServer can be retrieved as Image?
You need a converter to convert PDF to image and then display the same.
Have a look at these:
VB.NET Example for PDF to Image Converter SDK[^]
How To Convert PDF to Image Using Ghostscript API[^]
Once you have converted it, you can store/use the image as needed.
