C # Build a file format conversion Server

File format conversion is required for viewing office documents online, because the browser does not support opening office documents directly, therefore, in many cases, we need to convert these documents into formats that can be played by flash, but another problem arises. Some devices do not support flash. After testing the three versions, I finally got a better solution. First, most people know that flashpaper is used, but unfortunately this software is very old. Second, it uses office COM, but its disadvantages are very obvious, A lot of code is required to complete simple tasks and many configurations are required. The pain is self-evident. The third method is to use OpenOffice and jodconverter.

 

I. Required Software

Because jodconverter is written in Java, I have converted it into a C # class library, which avoids many events and makes no sense.

1. OpenOffice software (http://www.openoffice.org/download/index.html) can be directly installed by default

2. I encapsulated class library (http://files.cnblogs.com/yaozhenfa/jodconverter.net.rar)

 

2. Start OpenOffice

The author installed OpenOffice in c: \ Program Files (x86) \, so you need to run "cmd" in DOS (START-) and enter the following command:

1 C:\>"C:/Program Files (x86)/OpenOffice 4/program/soffice.exe" -accept=socket,hos2 t=0.0.0.0,port=8080;urp;-headless

 

Host indicates the IP address of the listener and port indicates the port. The setting here is 8080.

 

Iii. Test

Create a new console project in Vs and reference all the encapsulated class libraries.

 

Then write the following code:

 1 using com.artofsolving.jodconverter; 2 using com.artofsolving.jodconverter.openoffice.connection; 3 using com.artofsolving.jodconverter.openoffice.converter; 4 using java.io; 5 using System; 6 using System.Collections.Generic; 7 using System.Linq; 8 using System.Text; 9 10 namespace ConsoleApplication111 {12     class Program13     {14         static void Main(string[] args)15         {16             File inputFile = new File("c://test.doc");17             File outputFile = new File("c://test.pdf");18             OpenOfficeConnection connection = new SocketOpenOfficeConnection(8080);19             connection.connect();20             DocumentConverter converter = new OpenOfficeDocumentConverter(connection);21             converter.convert(inputFile, outputFile);22             connection.disconnect();23             System.Console.ReadKey();24         }25     }26 }

 

 

Here, the document to be tested by the pen is stored in the C drive and named as test.doc. The reader needs to modify the file according to his own situation. Here I will convert the doc to PDF, and of course it can also be converted to HTML.

 

I believe that you will need this solution soon.
