smtp发送带附件的邮件代码分享

前端技术 2023/09/09 .NET

该方式直接保存为HTML文件，也可以是文本文件，其它格式效果不是很好

accept@qq.com\");//接收邮箱
    byte[] bytes = System.Text.Encoding.Default.GetBytes
        (@\"<table><tr><td width=150>1234567891234567
        </td><td width=80>12345678</td></tr></table>\");
    MemoryStream ms = new MemoryStream(bytes);
    ContentType ct = new ContentType();
    //附件文件类型
    ct.MediaType = MediaTypeNames.Text.Html;
    //附件名称，可以是其它后缀名
    ct.Name = \"附件名称\" + DateTime.Now.ToString() + \".html\";
    mmsg.Attachments.Add(new Attachment(ms, ct));
    //SMTP简单邮件协议
    System.Net.Mail.SmtpClient sc
        = new System.Net.Mail.SmtpClient();
    sc.Host = \"127.0.0.1\";//主机地址
    sc.Port = 25;//端口
    //发送邮箱账号和密码
    sc.Credentials =
        new System.Net.NetworkCredential(\"account\", \"password\");
    //发送邮箱
    mmsg.From = new MailAddress(\"account@qq.com\");
    sc.Send(mmsg);
    //释放流资源
    ms.Close();
    ms.Dispose();

另附上一个.net使用smtp发送带附件邮件的实例

**********@gmail.com\"/>//Email Address
<add key=\"EmailPassword\" value=\"*********\"/> //Emial PWD
<add key=\"SmtpServer\" value=\"smtp.gmail.com\"/>
<add key=\"SmtpPort\" value=\"587\"/>
<--带附件版本->
var fromAddress = \"allenyinj@gmail.com\";
string fromPassword = \"yj1989120\";
const string subject = \"CV\";
var smtp = new SmtpClient
{
Host = \"smtp.gmail.com\",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress, fromPassword)
};
MailMessage email=new MailMessage(fromAddress, \"allen.yin.jun@gmail.com\");
email.Subject = \"INLINE attachment TEST\";
email.IsBodyHtml = true;
string attachmentPath = \"C:\\\\3.jpeg\";
Attachment inline = new Attachment(attachmentPath);
inline.ContentDisposition.Inline = true;
inline.ContentDisposition.DispositionType = DispositionTypeNames.Inline;
//inline.ContentId = \"1\";
//inline.ContentType.MediaType = \"image/png\";
inline.ContentType.Name = Path.GetFileName(attachmentPath);
email.Attachments.Add(inline);
email.Body = \"test\";
smtp.Send(email);
email.Dispose();
//如果没有路径，用Stream
Attachment letter = new Attachment(FileUploadLetter.FileContent, FileUploadLetter.PostedFile.ContentType);
letter.ContentDisposition.Inline = true;
letter.ContentDisposition.DispositionType = DispositionTypeNames.Inline;
//inline.ContentId = \"1\";
letter.ContentType.MediaType = FileUploadLetter.PostedFile.ContentType;
letter.ContentType.Name = Path.GetFileName(FileUploadLetter.PostedFile.FileName);
letter.Name = Path.GetFileName(FileUploadLetter.PostedFile.FileName);
