实现邮件发送功能

 

1：用到的命名空间

using System.Net.Mail;

using System.Net;

2：实现的静态类

public static class SendMail

{

    /// <summary>

    /// 发送邮件

    /// </summary>

    /// <param name="to">收件人邮件地址</param>

    /// <param name="from">发件人邮件地址</param>

    /// <param name="subject">邮件主题</param>

    /// <param name="body">邮件内容</param>

    /// <param name="username">登录smtp主机时用到的用户名,注意是邮件地址'@'前部分 </param>

    /// <param name="password">登录smtp主机时用到的用户密码</param>

    /// <param name="smtpHost">发送邮件用到的smtp主机</param>

    public static void Send(string to, string from, string subject, string body, string userName, string password, string smtpHost)

    {

        MailAddress from1 = new MailAddress(from);

        MailAddress to1 = new MailAddress(to);

        MailMessage message = new MailMessage(from1, to1);

        message.Subject = subject;//设置邮件主题

        message.IsBodyHtml = true;//设置邮件正文为html格式

        message.Body = body;//设置邮件内容

        SmtpClient client = new SmtpClient(smtpHost);

        //设置发送邮件身份验证方式

        //注意如果发件人地址是abc@def.com，则用户名是abc而不是abc@def.com

        client.Credentials = new NetworkCredential(userName, password);

        client.Send(message);

    }

}
