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：
1 private void TransHTMLEncoding(string strFilePath)
2 {
3 try
4 {
5 System.IO.StreamReader sr = new System.IO.StreamReader(strFilePath, Encoding.GetEncoding(0));
6 string 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 }
14 catch (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
