Asp.net: HTML preview docx document content

Since Gmail launched the Office document preview function, various mailboxes have followed up, but they cannot find mature documents, which is incredible and trade confidential?

A small requirement is to preview the doc document on the webpage,

One solution is to use code to operate the word "Save as" function and save it as HTML when uploading a DOC file,

For more information, see the Google "Asp.net preview Doc" keyword.

This method is limited
1. Each document generates an HTML copy and resource folder, causing serious space waste.

2. The server must install the office. Of course, you can also try to introduce the necessary DLL and copy the DCOM configuration according to the error message. Every time I go crazy, the last step is to install the office...

3. docx is not tested currently.

The general implementation is as follows. We sincerely remind you that it is best to install the office and try again.

After the related DLL (such as Word or Excel) is introduced, refer to the following code:

Using system; using system. data; using system. configuration; using system. collections; using system. web; using system. web. security; using system. web. ui; using system. web.

==================

Now the Chinese resources are unavailable, so I continued to look for it and found a foreigner's implementation, but only word2007 is supported. Because office2007 is based on openxml, of course it can be parsed by myself.

In this case, the URL at the end of .docx can be directly previewed and the download link generation rules are provided.
