如何将RAR文件附加到c＃中的电子邮件？ [英] How to attach a RAR file to an email in c#?

问题描述

欲发送具有用下面的代码多个附件的电子邮件，但它不为RAR文件工作。问题是什么？
。对于每个附件我有一个包含附件文件的一些属性，其内容的类：

 公共类AttachmentFile 
 {
 [StringLength（200）] 
公共字符串文件名{获得;组; } 
 [StringLength（15）] 
公共字符串扩展{搞定;组; } 
 [StringLength（100）] 
公共特征码{搞定;组; } 
公众的byte []内容{搞定;组; } 
 [StringLength（500）] 
公共字符串FULLPATH {搞定;组; } 
} 
  

Send方法如下所示：

 公共无效发送（字符串从，列表<串> recivers，串smtpHostName，弦乐主题，绳体，ICollection的< AttachmentFile> attachmentFiles）
 {
 MAILMESSAGE变种新= MAILMESSAGE（）; 
的foreach（在recivers VAR reciver）
 {
 mailMessage.To.Add（reciver）; 
} 
 
 mailMessage.Subject =主体; 
 mailMessage.From =新的MailAddress（@from）; 
 mailMessage.Body = RenderBody（体）; 
如果（attachmentFiles！= NULL）
 {
的foreach（在attachmentFiles VAR attachmentFile）
 {
变种的contentType =新System.Net.Mime.ContentType（系统。 Net.Mime.MediaTypeNames.Application.Octet）; 
 mailMessage.Attachments.Add（新附件（新的MemoryStream（attachmentFile.Content），应用程序/ RAR））; 
} 
} 
 
 mailMessage.IsBodyHtml = TRUE; 
 mailMessage.SubjectEncoding = Encoding.UTF8; 
变种SMTP =新SmtpClient {主机= smtpHostName}; 
 smtp.Send（MAILMESSAGE）; 
} 
  

解决方案

请写你的问题，因为短越好！龙的问题引起的独立的答案。
我不纠正你的代码，但你可以使用这个简单的代码附加一个RAR文件：

  VAR attachmentToSend =新的附件（pathOfYourFile）; 
 mailMessage.Attachments.Add（attachmentToSend）; 
  

I want to send an email that has multiple attachments using the following code but it doesn't work for RAR files. What is the problem? For every attachment I have a class that contains some properties of the attached file and its content:

public class AttachmentFile
{
    [StringLength(200)]
    public string FileName { get; set; }
    [StringLength(15)]
    public string Extension { get; set; }
    [StringLength(100)]
    public string Signature { get; set; }
    public byte[] Content { get; set; }
    [StringLength(500)]
    public string FullPath { get; set; } 
}

The Send method is shown here:

public void Send(string from, List<string> recivers, string smtpHostName, string subject, string body, ICollection<AttachmentFile> attachmentFiles)
{
    var mailMessage = new MailMessage();
    foreach (var reciver in recivers)
    {
        mailMessage.To.Add(reciver);
    }

    mailMessage.Subject = subject;
    mailMessage.From = new MailAddress(@from);
    mailMessage.Body = RenderBody(body);
    if (attachmentFiles != null)
    {
        foreach (var attachmentFile in attachmentFiles)
        {
            var contentType = new System.Net.Mime.ContentType(System.Net.Mime.MediaTypeNames.Application.Octet);
            mailMessage.Attachments.Add(new Attachment(new MemoryStream(attachmentFile.Content), "application/rar"));
        }
    }

    mailMessage.IsBodyHtml = true;
    mailMessage.SubjectEncoding = Encoding.UTF8;
    var smtp = new SmtpClient { Host = smtpHostName };
    smtp.Send(mailMessage);
}

解决方案

Please write your problem as short as possible! Long questions cause independent answers. I don't correct your code but you can attach a rar file using this simple code:

var attachmentToSend = new Attachment(pathOfYourFile);
mailMessage.Attachments.Add(attachmentToSend);
