问题描述

大家好
我想将sample.ics文件作为邮件附件发送.我尝试了以下代码，但无法正常工作.

Hi all
I want to send sample.ics file as an mail attachment. I tried the below code but not working.

            MailMessage m = new MailMessage();
SmtpClient sc = new SmtpClient();
string schLocation = "Conference Room";
string schSubject = "Business visit discussion";
string schDescription = "Schedule description";
System.DateTime schBeginDate = Convert.ToDateTime("7/8/2011 10:00:00 AM");
System.DateTime schEndDate = Convert.ToDateTime("7/8/2011 10:00:00 PM");
String[] contents = { "BEGIN:VCALENDAR",
"PRODID:-//Flo Inc.//FloSoft//EN",
BEGIN:VEVENT",
"DTSTART:" + schBeginDate.ToUniversalTime().ToString("yyyyMMdd\\THHmmss\\Z"), 
"DTEND:" + schEndDate.ToUniversalTime().ToString("yyyyMMdd\\THHmmss\\Z"), 
LOCATION:" + schLocation, 
"DESCRIPTION;ENCODING=QUOTED-PRINTABLE:" + schDescription,
"SUMMARY:" + schSubject, "PRIORITY:3", 
"END:VEVENT", "END:VCALENDAR" };
System.IO.File.WriteAllLines("D:\\mail\\sample1.ics", contents);
            
m.From = new MailAddress("[e-mail]", "displayname");
m.To.Add(new MailAddress("[e-mail]", "displayname");                
m.Subject = "Hi I have attached sample.ics file";
m.IsBodyHtml = true;
m.Body = "This is a Test Mail";
FileStream fs = new FileStream("D:\\mail\\sample1.ics", FileMode.Open, FileAccess.Read);
Attachment a = new Attachment(fs,"sample1.ics", MediaTypeNames.Application.Octet);
m.Attachments.Add(a);

sc.Host = "smtp.gmail.com";
sc.Port = 587;
sc.Credentials = new System.Net.NetworkCredential("[e-mail]","Password");
sc.EnableSsl = true;
sc.Send(m);
Console.WriteLine("Sent");
Console.ReadLine();

如果我注释掉该行，我可以发送邮件
m.Attachments.Add(a);
谁能告诉我我在哪里做错了...

I can able to send mail if i comment out the line
m.Attachments.Add(a);
can anyone please tell me where i had done mistake...

推荐答案

您需要创建MailAttachment，而不仅仅是附件的附件传递对象.

看一下这个技巧:使用C#发送电子邮件带有或不带有附件:通用例程. [ ^ ]

You need to create MailAttachment and not just Attachment object for attachments to pass on.

Have a look at this tip: Sending an Email in C# with or without attachments: generic routine.[^]
