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：
private void TransHTMLEncoding(string strFilePath)
{
try
{
System.IO.StreamReader sr = new System.IO.StreamReader(strFilePath, Encoding.GetEncoding());
string html = sr.ReadToEnd();
sr.Close();
html = System.Text.RegularExpressions.Regex.Replace(html, @"<meta[^>]*>", "<meta http-equiv=Content-Type content='text/html; charset=gb2312'>", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
System.IO.StreamWriter sw = new System.IO.StreamWriter(strFilePath, false, Encoding.Default); sw.Write(html);
sw.Close();
}
catch (Exception ex)
{
Page.RegisterStartupScript("alt", "<script>alert('" + ex.Message + "')</script>");
}
}
这样就可以正常在页面上正常显示了
