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;
10
11 // 打开文件
12 Type docsType = docs.GetType();
13 Word.Document doc = (Word.Document)docsType.InvokeMember( " Open " , System.Reflection.BindingFlags.InvokeMethod, null , docs, new Object[] { path, true , true });
14
15 // 转换格式，另存为
16 Type docType = doc.GetType();
17
18 string wordSaveFileName = savePath;
19
20 string strSaveFileName = savePath + wordFileName + " .html " ;
21
22 object saveFileName = ( object )strSaveFileName;
23
24 docType.InvokeMember( " SaveAs " , System.Reflection.BindingFlags.InvokeMethod, null , doc, new object [] { saveFileName, Word.WdSaveFormat.wdFormatFilteredHTML });
25
26 docType.InvokeMember( " Close " , System.Reflection.BindingFlags.InvokeMethod, null , doc, null );
27
28 // 退出 Word
29 wordType.InvokeMember( " Quit " , System.Reflection.BindingFlags.InvokeMethod, null , word, null );
30
31 return saveFileName.ToString();
32 }
[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 " ;
10 object ofmt = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml;
11 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);
12 object osave = false ;
13 workbook.Close(osave, Type.Missing, Type.Missing);
14 repExcel.Quit();
15
16 }
[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······
