The principle is actually very simple. For example, if you click "Save as", many formats will appear for you to choose from. This interface is called here. I have tried to use Apache OpenOffice for transcoding. Word, Execel, and Ppt can barely be converted (no complicated graphics), but the effect is not good. OpenOffice is powerless for other document types, later, we used the original Office interface for simplicity. The purpose of transcoding (Benefit): You can preview the document directly in the browser (because of the need for project team document sharing, so we developed such a thing, in combination with WebServer, transcode the file immediately after it is uploaded. Click this document to return to the transcoded file. The browser can directly browse the file, which is very convenient ~) This article briefly summarizes the advantages of using C #: 100% Perfect transcoding, Perfect! Insufficient: Only windows servers can be deployed ~ Advantages of using OpenOffice: cross-platform. Insufficient: the transcoding effect is not satisfactory ~ The preceding code is the core code. During the call, the following problems may occur, causing transcoding failure: 1. the document is in use. Solution: copy a copy before transcoding, and then transcode the copy ~ 2. The document is damaged. Solution: Change it after fixing ~ 3. The document has a password. Solution: no attempt ~ 4 .......
