C# 发送邮件 System.Net.Mail

C#要实现发送邮件功能很简单，微软已经帮我们搞定了大部分事情，话不多说，代码：

  1 public class Email
  2         {
  3             /// <summary>
  4             /// 发送者
  5             /// </summary>
  6             public string mailFrom { get; set; }
  7 
  8             /// <summary>
  9             /// 收件人
 10             /// </summary>
 11             public string[] mailToArray { get; set; }
 12 
 13             /// <summary>
 14             /// 抄送
 15             /// </summary>
 16             public string[] mailCcArray { get; set; }
 17 
 18             /// <summary>
 19             /// 标题
 20             /// </summary>
 21             public string mailSubject { get; set; }
 22 
 23             /// <summary>
 24             /// 正文
 25             /// </summary>
 26             public string mailBody { get; set; }
 27 
 28             /// <summary>
 29             /// 发件人密码
 30             /// </summary>
 31             public string mailPwd { get; set; }
 32 
 33             /// <summary>
 34             /// SMTP邮件服务器
 35             /// </summary>
 36             public string host { get; set; }
 37 
 38             /// <summary>
 39             /// 正文是否是html格式
 40             /// </summary>
 41             public bool isbodyHtml { get; set; }
 42 
 43             /// <summary>
 44             /// 附件
 45             /// </summary>
 46             public string[] attachmentsPath { get; set; }
 47 
 48             public bool Send()
 49             {
 50                 //使用指定的邮件地址初始化MailAddress实例
 51                 MailAddress maddr = new MailAddress(mailFrom);
 52                 //初始化MailMessage实例
 53                 MailMessage myMail = new MailMessage();
 54 
 55 
 56                 //向收件人地址集合添加邮件地址
 57                 if (mailToArray != null)
 58                 {
 59                     for (int i = 0; i < mailToArray.Length; i++)
 60                     {
 61                         myMail.To.Add(mailToArray[i].ToString());
 62                     }
 63                 }
 64 
 65                 //向抄送收件人地址集合添加邮件地址
 66                 if (mailCcArray != null)
 67                 {
 68                     for (int i = 0; i < mailCcArray.Length; i++)
 69                     {
 70                         myMail.CC.Add(mailCcArray[i].ToString());
 71                     }
 72                 }
 73                 //发件人地址
 74                 myMail.From = maddr;
 75 
 76                 //电子邮件的标题
 77                 myMail.Subject = mailSubject;
 78 
 79                 //电子邮件的主题内容使用的编码
 80                 myMail.SubjectEncoding = Encoding.UTF8;
 81 
 82                 //电子邮件正文
 83                 myMail.Body = mailBody;
 84 
 85                 //电子邮件正文的编码
 86                 myMail.BodyEncoding = Encoding.Default;
 87 
 88                 myMail.Priority = MailPriority.High;
 89 
 90                 myMail.IsBodyHtml = isbodyHtml;
 91 
 92                 //在有附件的情况下添加附件
 93                 try
 94                 {
 95                     if (attachmentsPath != null && attachmentsPath.Length > 0)
 96                     {
 97                         Attachment attachFile = null;
 98                         foreach (string path in attachmentsPath)
 99                         {
100                             attachFile = new Attachment(path);
101                             myMail.Attachments.Add(attachFile);
102                         }
103                     }
104                 }
105                 catch (Exception err)
106                 {
107                     throw new Exception("在添加附件时有错误:" + err);
108                 }
109 
110                 SmtpClient smtp = new SmtpClient();
111                 //指定发件人的邮件地址和密码以验证发件人身份
112                 smtp.Credentials = new System.Net.NetworkCredential(mailFrom, mailPwd);
113 
114 
115                 //设置SMTP邮件服务器
116                 smtp.Host = host;
117                 smtp.EnableSsl = true;
118                 try
119                 {
120                     //将邮件发送到SMTP邮件服务器
121                     smtp.Send(myMail);
122                     return true;
123 
124                 }
125                 catch (System.Net.Mail.SmtpException)
126                 {
127                     return false;
128                 }
129 
130             }
131         }

有上面这个类，直接调用Send访问就好了

 1 Email email = new Email();         
 2 email.mailFrom = 账号;         
 3 email.mailPwd = 密码;
 4 email.mailSubject = titile;//标题
 5 email.mailBody = content;//正文
 6 email.isbodyHtml = true;    //是否是HTML
 7 email.host = 邮箱host;//如果是QQ邮箱则：smtp:qq.com,依次类推
 8 email.mailToArray = new string[] { emailaddress };//接收者邮件集合
 9 email.mailCcArray = new string[] { };//抄送者邮件集合  
10 email.Send();

至此就完成邮件发送功能了，快试试吧
