dotNet发送邮件

这里介绍两种方式：

1、配置文件(Web.config) + 少量C#代码

在 configuration 节点下添加

  <system.net>
    <mailSettings>
      <smtp from="baidu@163.com">
        <network host="smtp.163.com" password="baidu" port="25" userName="baidu" defaultCredentials="false"/>
      </smtp>
    </mailSettings>
  </system.net>

发送邮件方法：

/// <summary>
/// 发送邮件
/// </summary>
private void SendMail()
{
    System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
    message.From = new System.Net.Mail.MailAddress("baidu@163.com");//发送人邮箱地址，与smtp节点中的from值一致
    message.To.Add(new System.Net.Mail.MailAddress("taobao@163.com"));//接收人邮箱地址
    message.Subject = "hello";
    message.Body = "<b>taobao</b>";
    message.IsBodyHtml = true;

    System.Net.Mail.SmtpClient smtpclient = new System.Net.Mail.SmtpClient();
    smtpclient.Send(message);
}

2、纯 C#代码

/// <summary>
/// 发送邮件
/// </summary>
private void SendMail()
{
    System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
    message.From = new System.Net.Mail.MailAddress("baidu@163.com");//发送人邮箱地址，与smtp节点中的from值一致
    message.To.Add(new System.Net.Mail.MailAddress("taobao@163.com"));//接收人邮箱地址
    message.Subject = "hello";
    message.Body = "<b>taobao</b>";
    message.IsBodyHtml = true;

    System.Net.Mail.SmtpClient smtpclient = new System.Net.Mail.SmtpClient("smtp.163.com", 25);
    smtpclient.Credentials = new System.Net.NetworkCredential("baidu", "baidu");//参数分别是邮箱用户名和密码
    smtpclient.Send(message);
}
