Office系列在线预览

最近客户有个需求，需要在线预览PPT、Excel、Word,开始打算用第三方组建去读取 office系列，然后生成html,这样的话样式相当于丢了，只剩下数据，而且第三方组件对office版本支持不够完善，最关键的是还是样式丢了！

最后决定，用户在上传的过程中调用office API里面的saveAs，自动生成了静态html,预览的时候就直接访问的该html页面。

[a].WordToHtml

 1  public static string WordToHtml(string path, string savePath, string wordFileName)

 2         {

 3 

 4             //在此处放置用户代码以初始化页面

 5             Microsoft.Office.Interop.Word.Application word = new Word.Application();

 6 

 7             Type wordType = word.GetType();

 8 

 9             Word.Documents docs = word.Documents;

 

             //打开文件

             Type docsType = docs.GetType();

             Word.Document doc = (Word.Document)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { path, true, true });

 

             //转换格式，另存为

             Type docType = doc.GetType();

 

             string wordSaveFileName = savePath;

 

             string strSaveFileName = savePath+wordFileName + ".html";

 

             object saveFileName = (object)strSaveFileName;

 

             docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { saveFileName, Word.WdSaveFormat.wdFormatFilteredHTML });

 

             docType.InvokeMember("Close", System.Reflection.BindingFlags.InvokeMethod, null, doc, null);

 

             //退出 Word

             wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null);

 

             return saveFileName.ToString();

         }

 

[b].ExcelToHtml

 1  public static void ExcelToHtml(string path,string savePath, string wordFileName)

 2         {

 3             string str = string.Empty;

 4             Microsoft.Office.Interop.Excel.Application repExcel = new Microsoft.Office.Interop.Excel.Application();

 5             Microsoft.Office.Interop.Excel.Workbook workbook = null;

 6             Microsoft.Office.Interop.Excel.Worksheet worksheet = null;

 7             workbook = repExcel.Application.Workbooks.Open(path, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

 8             worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];

 9             object htmlFile =savePath+wordFileName+ ".html";

             object ofmt = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml;

             workbook.SaveAs(htmlFile, ofmt, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

             object osave = false;

             workbook.Close(osave, Type.Missing, Type.Missing);

             repExcel.Quit();

            

         }

 

[c].PPTToHtml

 public static  void PPTToHtml(string path, string savePath, string wordFileName)

        {

            Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application();

            string strSourceFile = path;

            string strDestinationFile = savePath+wordFileName+".html";

            Microsoft.Office.Interop.PowerPoint.Presentation prsPres = ppApp.Presentations.Open(strSourceFile, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse);

            prsPres.SaveAs(strDestinationFile, Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsHTML, MsoTriState.msoTrue);

            prsPres.Close();

            ppApp.Quit();



        }

 

当完成该功能的时候，上帝那边传来噩耗，他们表示不愿意在服务器上安装office，所以我们继续寻找解决方案······
