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
