Excel⽂件转HTML，返回相对路径

12
13//打开⽂件，n.FullPath是⽂件路径
14 workbook = repExcel.Application.Workbooks.Open(strFile, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing
15 worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];

22 DateTime dt = DateTime.Now;
23//以yyyymmdd形式⽣成⼦⽂件夹名
24string strFileSubFolder = dt.Year.ToString();
25 strFileSubFolder += (dt.Month < 10) ? ("0" + dt.Month.ToString()) : dt.Month.ToString();
26 strFileSubFolder += (dt.Day < 10) ? ("0" + dt.Day.ToString()) : dt.Day.ToString();
27string strFilePath = strFileFolder + strFileSubFolder + "/";

32 Directory.CreateDirectory(Server.MapPath(strFilePath));
33 }
34string ConfigPath = Server.MapPath(strFilePath + filename + ".html");
35object savefilename = (object)ConfigPath;
36
37object ofmt = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml;
38//进⾏另存为操作
39 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.Mis
40object osave = false;
41//逐步关闭所有使⽤的对象
42 workbook.Close(osave, Type.Missing, Type.Missing);
43 repExcel.Quit();
44 System.Runtime.InteropServices.Marshal.ReleaseComObject(worksheet);
45 worksheet = null;
46//垃圾回收
47 GC.Collect();
48 System.Runtime.InteropServices.Marshal.ReleaseComObject(workbook);
49 workbook = null;
50 GC.Collect();
51 System.Runtime.InteropServices.Marshal.ReleaseComObject(repExcel.Application.Workbooks);
52 GC.Collect();
53 System.Runtime.InteropServices.Marshal.ReleaseComObject(repExcel);
54 repExcel = null;
55 GC.Collect();
56//依据时间杀灭进程
57 System.Diagnostics.Process[] process = System.Diagnostics.Process.GetProcessesByName("EXCEL");
58foreach (System.Diagnostics.Process p in process)
59 {
60if (DateTime.Now.Second - p.StartTime.Second > 0 && DateTime.Now.Second - p.StartTime.Second < 5)
61 {
62 p.Kill();
63 }
64 }
65
66return (strFilePath + filename + ".html");
67 }
这⾥可能会遇到⼀个问题，由于转化为HTML⽂件的页⾯编码可能使得浏览器⽆法正确解读，所以需要转码，转换代码如下：
1privatevoid TransHTMLEncoding(string strFilePath)
2 {
3try
4 {
5 System.IO.StreamReader sr = new System.IO.StreamReader(strFilePath, Encoding.GetEncoding(0));
6string html = sr.ReadToEnd();
7 sr.Close();
8 html = System.Text.RegularExpressions.Regex.Replace(html, @"<meta[^>]*>", "<meta http-equiv=Content-Type content='text/html; charset=gb2312'>", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
9 System.IO.StreamWriter sw = new System.IO.StreamWriter(strFilePath, false, Encoding.Default);
10
11 sw.Write(html);
12 sw.Close();
13 }
14catch (Exception ex)
15 {
16 Page.RegisterStartupScript("alt", "<script>alert('" + ex.Message + "')</script>");
17 }
18 }
这样就可以正常在页⾯上正常显⽰了
