首先，web.config设置邮件服务器配置

1 <system.net>
2     <mailSettings>
3       <smtp from="" deliveryMethod="Network">
4         <network host="" port="25" userName="" password="" targetName=""/>
5       </smtp>
6     </mailSettings>
7 </system.net>
View Code


当然，其中空白的值，需要根据各自的情况填写

获取配置的代码：

SmtpSection smtpCfg = NetSectionGroup.GetSectionGroup(WebConfigurationManager.OpenWebConfiguration("~/web.config")).MailSettings.Smtp;

接下来创建MailMessage对象，并设置属性

 1 System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();
 2             msg.From = new System.Net.Mail.MailAddress(smtpCfg.From, smtpCfg.Network.TargetName, System.Text.Encoding.UTF8);
 3             //msg.To.Add("收件人地址");
 4             string[] temp = to.Trim(',').Split(',');
 5             foreach (var item in temp)
 6             {
 7                 msg.To.Add(item + "@XX.com.cn");
 8             }
 9             //msg.CC.Add("抄送人地址");
10             if (!string.IsNullOrEmpty(cc))
11             {
12                 temp = cc.Trim(',').Split(',');
13                 foreach (var item in temp)
14                 {
15                     msg.CC.Add(item + "@XX.com.cn");
16                 }
17             }
18             msg.Subject = title;
19             msg.Body = body;
20             msg.BodyEncoding = System.Text.Encoding.UTF8;//正文编码
21             msg.IsBodyHtml = true;
22             msg.Priority = System.Net.Mail.MailPriority.High;//优先级
　　　　　　　　　

完整代码：
此处收件人，抄送人默认是统一的邮箱后缀，默认收件人，抄送人传的只是邮件名，非完整邮箱地址；当然你也可以改进，直接收件人，抄送人是完整邮箱地址

 1  /// <summary>
 2         /// 发送邮件
 3         /// </summary>
 4         /// <param name="to">收件人【多个以','分隔】</param>
 5         /// <param name="title">标题</param>
 6         /// <param name="body">邮件正文</param>
 7         /// <param name="cc">抄送人【多个以','分隔】</param>
 8         private void SendMail(string to, string title, string body, string cc="")
 9         {
10             SmtpSection smtpCfg = NetSectionGroup.GetSectionGroup(WebConfigurationManager.OpenWebConfiguration("~/web.config")).MailSettings.Smtp;
11             
12             System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();
13             msg.From = new System.Net.Mail.MailAddress(smtpCfg.From, smtpCfg.Network.TargetName, System.Text.Encoding.UTF8);
14             //msg.To.Add("收件人地址");
15             string[] temp = to.Trim(',').Split(',');
16             foreach (var item in temp)
17             {
18                 msg.To.Add(item + "@XX.com.cn");
19             }
20             //msg.CC.Add("抄送人地址");
21             if (!string.IsNullOrEmpty(cc))
22             {
23                 temp = cc.Trim(',').Split(',');
24                 foreach (var item in temp)
25                 {
26                     msg.CC.Add(item + "@XX.com.cn");
27                 }
28             }
29             msg.Subject = title;
30             msg.Body = body;
31             msg.BodyEncoding = System.Text.Encoding.UTF8;//正文编码
32             msg.IsBodyHtml = true;
33             msg.Priority = System.Net.Mail.MailPriority.High;//优先级
34 
35             
36             System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient(smtpCfg.Network.Host,smtpCfg.Network.Port);
37             
38             smtp.Credentials = new System.Net.NetworkCredential(smtpCfg.Network.UserName, smtpCfg.Network.Password);
39             try
40             {
41                 //smtp.SendAsync(msg, "");
42                 //smtp.SendMailAsync("发件人地址","收件人地址","邮件主题","邮件正文");
43                 smtp.SendMailAsync(msg);
44             }
45             catch (Exception e)
46             {
47                 smtp.Send(msg);
48                 //throw new Exception(e.ToString());
49             }
50         }
