有些时候可能需要将Excel,ppt和word转化为html在页面上显示。我从网上查到一些代码，记录在这里以供需要的朋友参考
1.将word转化为html显示
//======================================================================== // 函数名: WordToHtml /// <summary> /// Word转成Html /// </summary> /// <param name="wordfilename">word文件名</param> /*======================================================================= 变更记录 序号 更新日期 开发者 变更内容 0001 2008/07/22 张 新建 =======================================================================*/ public static string WordToHtml(object wordfilename) { //在此处放置用户代码以初始化页面 word.Application word = new word.Application(); Type wordtype = word.GetType(); 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[] { wordfilename, true, true }); //转换格式，另存为 Type doctype = doc.GetType(); string wordsavefilename = wordfilename.ToString(); string strsavefilename = wordsavefilename.Substring(0, wordsavefilename.Length - 3) + "html"; object savefilename = (object)strsavefilename; doctype.InvokeMember("saveas", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { savefilename, Microsoft.Office.Interop.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(); }
2.将PPT转化为html显示
//======================================================================== // 函数名: PPTToHtml /// <summary> /// PPT转成Html /// </summary> /// <param name="pptFilename">PPT文件名</param> /*======================================================================= 变更记录 序号 更新日期 开发者 变更内容 0001 2008/07/22 张 新建 =======================================================================*/ public string PPTToHtml(string pptFilename) { //被转换的html文档保存的位置 string saveFileName = pptFilename + ".html"; Microsoft.Office.Interop.PowerPoint.Application ppt = new Microsoft.Office.Interop.PowerPoint.Application(); Microsoft.Office.Core.MsoTriState m1 = new MsoTriState(); Microsoft.Office.Core.MsoTriState m2 = new MsoTriState(); Microsoft.Office.Core.MsoTriState m3 = new MsoTriState(); Microsoft.Office.Interop.PowerPoint.Presentation pp = ppt.Presentations.Open(pptFilename, m1, m2, m3); pp.SaveAs(saveFileName, Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsHTML, Microsoft.Office.Core.MsoTriState.msoTriStateMixed); pp.Close(); //返回文件名 return saveFileName; }
3.将Excel转化为html显示
//======================================================================== // 函数名: ExcelToHtml /// <summary> /// Excel转成Html /// </summary> /// <param name="excelFileName">Excel文件名</param> /*======================================================================= 变更记录 序号 更新日期 开发者 变更内容 0001 2008/07/22 张 新建 =======================================================================*/ public string ExcelToHtml(string excelFileName) { //实例化Excel Microsoft.Office.Interop.Excel.Application repExcel = new Microsoft.Office.Interop.Excel.Application(); Microsoft.Office.Interop.Excel.Workbook workbook = null; Microsoft.Office.Interop.Excel.Worksheet worksheet = null; //打开文件，n.FullPath是文件路径 workbook = repExcel.Application.Workbooks.Open(excelFileName, 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); worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1]; string filesavefilename = excelFileName.ToString(); string strsavefilename = filesavefilename.Substring(0, filesavefilename.Length - 3) + "html"; object savefilename = (object)strsavefilename; object ofmt = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml; //进行另存为操作 workbook.SaveAs(savefilename, 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; //逐步关闭所有使用的对象 workbook.Close(osave, Type.Missing, Type.Missing); repExcel.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComObject(worksheet); worksheet = null; //垃圾回收 GC.Collect(); System.Runtime.InteropServices.Marshal.ReleaseComObject(workbook); workbook = null; GC.Collect(); System.Runtime.InteropServices.Marshal.ReleaseComObject(repExcel.Application.Workbooks); GC.Collect(); System.Runtime.InteropServices.Marshal.ReleaseComObject(repExcel); repExcel = null; GC.Collect(); //依据时间杀灭进程 System.Diagnostics.Process[] process = System.Diagnostics.Process.GetProcessesByName("EXCEL"); foreach (System.Diagnostics.Process p in process) { if (DateTime.Now.Second - p.StartTime.Second > 0 && DateTime.Now.Second - p.StartTime.Second < 5) { p.Kill(); } } return savefilename.ToString(); }
以上是转换成为html文件的方法，转换成功后会在文件夹下会生对应的图片文件夹，和样式文件，和html文件。其中如果Excel中包含多个sheet时，转化后的html会包含多个tab,如果想每个sheet转化为一个页面,则需要修改代码
