使用代码将附件添加到Outlook日历邀请 [英] Add Attachment to an outlook calender invite using code

问题描述

大家好，

  我可以使用c＃代码创建和发送Outlook邀请。我现在想要
为会议邀请添加附件并使用代码发送而不会丢失当前结构作为Outlook邀请电子邮件。请帮我解决。

<请注意，我的会议请求就像普通的Outlook邀请，而不是电子邮件的附件。

解决方案1我尝试过：当我使用下面的注释代码添加附件时，我丢失了outlook邀请格式并获得邀请，就像我带有附件的电子邮件一样。

 附件附件=新附件（"我的文件位置在这里"）;  
  msg.Attachments.Add（附件）;  

解决方案2我试过：没有帮助我获得附件和邀请但不会破坏邀请

您是否可以使用嵌入式附件？请参阅派生自AttachmentBase的类LinkedResource。

Hi All,

   I am able to create and send outlook invite using c# code. i now want to add an attachment to the meeting invite and send using code without losing the current structure as outlook invitation email.Please help me how.

Note my meeting request goes like an normal outlook invite and not like an attachment to an email.

Solution 1 i tried :When i add an attachment using the commented code below i lost the outlook invitation format and get the invitation like an email with the attachment which i have given.

Attachment attachment = new Attachment("my file location goes here");
msg.Attachments.Add(attachment);

Solution 2 i tried : doesnt help me get the attachment along with invite but doesn't spoil the invite

 string filepath ="C:\\RamCharan\\Projects\\temp\\Invitation_MeetingID_GOES_HERE.mht";
 str.AppendLine(string.Format("ATTACH;FMTTYPE=message/rfc822:{0}",filepath)); 

public string BookMeeting()
 {
 SmtpClient sc = new SmtpClient();
 sc.Host = "<smtp ip address goes here>";


 MailMessage msg = new MailMessage();
 msg.From = new MailAddress("emailid goes here", "name goes here");

 msg.To.Add("sender email address goes here");

 Guid meetingID = Guid.NewGuid();

 msg.Subject = "Create Meeting ID" + meetingID + "at " + DateTime.Now.ToString();
 msg.Body = "Please let me know when you get my emails.Here is the Body Content . ";
 msg.BodyEncoding = System.Text.Encoding.UTF8 ;

 StringBuilder str = new StringBuilder();

 str.AppendLine("BEGIN:VCALENDAR");
 str.AppendLine("PRODID:-//Ahmed Abu Dagga Blog");
 str.AppendLine("VERSION:2.0");
 str.AppendLine("METHOD:REQUEST");
 str.AppendLine("BEGIN:VEVENT");
 str.AppendLine(string.Format("DTSTART:{0:yyyyMMddTHHmmssZ}", DateTime.Now)); //startTime
 str.AppendLine(string.Format("DTSTAMP:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow));
 str.AppendLine(string.Format("DTEND:{0:yyyyMMddTHHmmssZ}", DateTime.Now.AddMinutes(31)));//endTime
 str.AppendLine("LOCATION: Method 1 location is ram desk again");
 str.AppendLine(string.Format("UID:{0}", meetingID));
 str.AppendLine(string.Format("DESCRIPTION:{0}", msg.Body));
 str.AppendLine(string.Format("X-ALT-DESC;FMTTYPE=text/html:{0}", msg.Body));
 str.AppendLine(string.Format("SUMMARY:{0}", msg.Subject));
 str.AppendLine(string.Format("ORGANIZER:MAILTO:{0}", msg.From.Address));

 for (int i = 0; i < msg.To.Count; i++)
 {
 str.AppendLine(string.Format("ATTENDEE;ROLE=REQ-PARTICIPANT;CN=\"{0}\";RSVP=TRUE:mailto:{1}", msg.To[i].DisplayName, msg.To[i].Address));
 //str.AppendLine(string.Format("ATTENDEE;CN=\"{0}\";RSVP=TRUE:mailto:{1}", msg.To[1].DisplayName, msg.To[1].Address));
 }

 //Adding organizer to send email 
 msg.To.Add(new MailAddress(msg.From.Address, msg.From.DisplayName));
 str.AppendLine(string.Format("ATTENDEE;PARTSTAT=ACCEPTED;CN=\"{0}\":mailto:{1}",
 msg.To[msg.To.Count - 1].DisplayName, msg.To[msg.To.Count - 1].Address));

 //Adding this attachment below is spoiling the invite
 //Attachment attachment = new Attachment("my file location goes here");
 //msg.Attachments.Add(attachment);
 
 //below doesnt help me get the attachment along with invite but doesn't spoil the invite
 // string filepath ="C:\\RamCharan\\Projects\\temp\\Invitation_MeetingID_GOES_HERE.mht";
 //str.AppendLine(string.Format("ATTACH;FMTTYPE=message/rfc822:{0}",filepath)); 

 

 str.AppendLine("BEGIN:VALARM");
 str.AppendLine("TRIGGER:-PT15M");
 str.AppendLine("ACTION:DISPLAY");
 str.AppendLine("DESCRIPTION:Reminder");
 str.AppendLine("END:VALARM");
 str.AppendLine("END:VEVENT");
 str.AppendLine("END:VCALENDAR");
 System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType("text/calendar");
 ct.Parameters.Add("method", "REQUEST");
 AlternateView avCal = AlternateView.CreateAlternateViewFromString(str.ToString(), ct);
 msg.AlternateViews.Add(avCal);
 
 sc.Send(msg);

 return "Meeting id is " + meetingID + " : Created Sucessfully at " + DateTime.Now.ToString();
 }

Will you be OK with embedded attachment instead? See class LinkedResource that derives from AttachmentBase.
