C# 含有图片的html邮件发送
在做这种邮件发送的时候,我一般是用html编写一个邮件模板
例:
<html> <head> <title></title> </head> <body> <table> <thead> <tr> <th>Name</th> <th>Age</th> </tr> </thead> <tbody> <tr> <td>$Name$<img src="cid:ico02" /></td> <td>$Age$<img src="cid:ico24" /></td> </tr> </tbody> </table> </body> </html>
这个是邮件模板 ,img标签的图片我和这个html页面放在一个文件夹里面.
再来后台代码
public void Send(string UserAccountMailAddress,string Pwd,List<string> ToUserMailAddress) { string tempfile = Server.MapPath("/mails/MasterHtml.htm"); string strIO = string.Empty; Encoding code = Encoding.GetEncoding("gb2312"); StreamReader sr; try { sr = new StreamReader(tempfile, code); strIO = sr.ReadToEnd(); sr.Close(); } catch(Exception ex) { Response.Write(ex.Message); return; } strIO = strIO.Replace("$Name$","张三"); //这里是对html中的替换 strIO = strIO.Replace("$Age$", "22"); //这里是对html中的替换 MailModel msg = new MailModel(); string Content = strIO; // StrIO替换后的html字符串 string Address = "zhangsan@qq.com"; string Subject = "test"; SendMailMsg(Address,Subject,Content,"123"); } /// <summary> /// 邮件发送 /// </summary> /// <param name="Address"></param> /// <param name="Subject"></param> /// <param name="Content"></param> /// <param name="Pwd"></param> public void SendMailMsg(string AddressSend,string Subject,string Content,string Pwd,string AddressReceive) { try { SmtpClient client = new SmtpClient("mail.sina.com", 25); MailAddress address = new MailAddress(, "mailsend", Encoding.UTF8); client.Credentials = new NetworkCredential(AddressSend,Pwd); client.DeliveryMethod = SmtpDeliveryMethod.Network; MailMessage message = new MailMessage(); message.From = AddressSend; string[] ToAddress = AddressReceive.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries); for (int i = 0; i < ToAddress.Length; i++) { message.To.Add(new MailAddress(ToAddress[i])); } message.Body = msg.Content; message.BodyEncoding = Encoding.UTF8; message.Subject = msg.Subject + "（系统自动邮件,请勿答复）"; #region 邮件发图 message.Attachments.Add(new Attachment(Server.MapPath("/mails/ico02.gif"))); message.Attachments[0].ContentId = "ico02"; message.Attachments[0].ContentDisposition.Inline = true; message.Attachments.Add(new Attachment(Server.MapPath("/mails/ico24.gif"))); message.Attachments[1].ContentId = "ico24"; message.Attachments[1].ContentDisposition.Inline = true; #endregion message.SubjectEncoding = Encoding.UTF8; message.IsBodyHtml = true; message.Sender = new MailAddress("XX", "XX", Encoding.GetEncoding("GB2312")); message.Priority = MailPriority.High; client.Send(message); } catch (Exception ex) { ex.Message.ToString(); } }
总结一下,其实邮件发送图片就是控制内容的格式和附件的发送
