C# SendMail发送邮件功能实现

最近因为用的发送邮件的地方，就查询了资料，总结以下几个方法

　　1、利用新浪邮箱发送

　　2、利用公司邮箱发送

　　3、利用CDO发送，这种方式要引用Interop.ADODB.dll（http://www.nodevice.com/dll/Interop_ADODB_dll/item20357.html）和Interop.CDO.dll（）两个文件

具体代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Mail;
using System.Data;

using CDO;
using ADODB;
namespace SendMailTest
{
 class Program
 {
 static void Main(string[] args)
 {
  SendMail();
 }

 public static string SendMsg()
 {
  DataTable dt = new DataTable();
  dt.Columns.Add("name");
  dt.Columns.Add("date");
  dt.Columns.Add("area");
  dt.Columns.Add("orgnizer");
  dt.Columns.Add("keyword");

  for (int i = 0; i < 10; i++)
  {
  DataRow dr = dt.NewRow();
  dr["name"] = "北文中心影视产权交易平台•影视项目路演季---路演项目征集" + i;
  dr["date"] = "2017-06-30";
  dr["area"] = "北京市 北京电影学院文创园（平房园区）" + i;
  dr["orgnizer"] = "北文中心影视产权交易" + i;
  dr["keyword"] = "影视" + i;
  dt.Rows.Add(dr);

  }

  string MailBody = "
以下内容为系统自动发送，请勿直接回复，谢谢。
";
  MailBody += "
";
  MailBody += "
";
  for (int hcol = 0; hcol < dt.Columns.Count; hcol++)
  {
  MailBody += "";
  }
  MailBody += "";

  for (int row = 0; row < dt.Rows.Count; row++)
  {
  MailBody += "";
  for (int col = 0; col < dt.Columns.Count; col++)
  {
   MailBody += "";
  }
  MailBody += "";
  }
  MailBody += "
   ";
  MailBody += dt.Columns[hcol].ColumnName;
  MailBody += "   
   ";
   MailBody += dt.Rows[row][col].ToString();
   MailBody += "   
";
  MailBody += "

"; return MailBody; } public static void SendMail() { MailMessage msg = new MailMessage(); msg.To.Add("[email protected]"); msg.CC.Add("[email protected]"); msg.From = new MailAddress("[email protected]", "ffff", System.Text.Encoding.UTF8); /* 上面3个参数分别是发件人地址（可以随便写），发件人姓名，编码*/ msg.Subject = "这是测试邮件";//邮件标题 msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码 //msg.Body = "邮件内容";//邮件内容 msg.Body = SendMsg(); msg.BodyEncoding = System.Text.Encoding.UTF8;//邮件内容编码 msg.IsBodyHtml = true;//是否是HTML邮件 msg.Priority = MailPriority.High;//邮件优先级 SmtpClient client = new SmtpClient(); //client.Host = "smtp.ctrchina.cn"; client.Host = "210.77.136.200"; client.Port = 465; //client.EnableSsl = true;//经过ssl加密 client.Credentials = new System.Net.NetworkCredential("[email protected]", "password"); object userState = msg; try { //client.SendAsync(msg, userState); client.Send(msg); } catch (System.Net.Mail.SmtpException ex) { return; } } public static void SendSinaMail() { MailMessage msg = new MailMessage(); msg.To.Add("[email protected]"); //msg.To.Add("[email protected]"); msg.CC.Add("[email protected]"); msg.From = new MailAddress("[email protected]", "shao_sks", System.Text.Encoding.UTF8); /* 上面3个参数分别是发件人地址（可以随便写），发件人姓名，编码*/ msg.Subject = "这是测试邮件";//邮件标题 msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码 //msg.Body = "邮件内容";//邮件内容 msg.Body = SendMsg(); msg.BodyEncoding = System.Text.Encoding.UTF8;//邮件内容编码 msg.IsBodyHtml = true;//是否是HTML邮件 msg.Priority = MailPriority.High;//邮件优先级 SmtpClient client = new SmtpClient(); client.Host = "smtp.sina.com"; client.Port = 25; //client.EnableSsl = true;//经过ssl加密 client.Credentials = new System.Net.NetworkCredential("username", "password"); object userState = msg; try { //client.SendAsync(msg, userState); client.Send(msg); } catch (System.Net.Mail.SmtpException ex) { return; } } public static void SenMail1() { try { CDO.Message oMsg = new CDO.Message(); Configuration MyConfig = new ConfigurationClass(); Fields MyFields = MyConfig.Fields; MyFields[@"http://schemas.microsoft.com/cdo/configuration/sendusing"].Value = 2; MyFields[@"http://schemas.microsoft.com/cdo/configuration/smtpserverport"].Value = 465; MyFields[@"http://schemas.microsoft.com/cdo/configuration/smtpserver"].Value = "210.77.136.200"; MyFields.Update(); oMsg.Configuration = MyConfig; oMsg.Subject = "Test SMTP2911111"; oMsg.HTMLBody = SendMsg(); oMsg.From = "[email protected]"; oMsg.To = "[email protected]"; oMsg.Send(); } catch (Exception ex) { return; } } } }
