Generate a thumbnail of a Word document

问题

I have a website where users upload Word documents and I want to display thumbnails of these word documents. If anyone of you knows how to display the first page of a Word file as an image using C# please tell me.

Also if you know a trusted .NET library to convert word files to images that requires no office interop that would be great.

Take a look at this article. It's in VB, but it lets you extract the thumbnail image that Windows Explorer uses for Office documents and regular images.

ShellFile shellFile = ShellFile.FromFilePath(pathToYourFile);
Bitmap shellThumb = shellFile.Thumbnail.ExtraLargeBitmap;

It's Microsoft's API Code Pack

I found this question (7 yrs later) while searching for a similar solution. I'm evaluating 2JPEG and it appears to support 275 formats including Word, Excel, Publisher & Powerpoint files. fCoder recommends running 2JPEG as a scheduled background task. The command line syntax is pretty comprehensive.

Here's a sample snippet to generate a thumbnail for a specific file:

2jpeg.exe -src "c:\files\myfile.docx" -dst "c:\files" -oper Resize size:"100 200" fmode:fit_width -options pages:"1" scansf:no overwrite:yes template:"{Title}_thumb.jpg" silent:yes
