Ｃ＃ 将Excel,ppt和word转化为html
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>

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>

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>

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
