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······
