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：

public class Email
        {
            /// <summary>
            /// 发送者
            /// </summary>
            public string mailFrom { get; set; }

            /// <summary>
            /// 收件人
            /// </summary>
            public string[] mailToArray { get; set; }

            /// <summary>
            /// 抄送
            /// </summary>
            public string[] mailCcArray { get; set; }

            /// <summary>
            /// 标题
            /// </summary>
            public string mailSubject { get; set; }

            /// <summary>
            /// 正文
            /// </summary>
            public string mailBody { get; set; }

            /// <summary>
            /// 发件人密码
            /// </summary>
            public string mailPwd { get; set; }

            /// <summary>
            /// SMTP邮件服务器
            /// </summary>
            public string host { get; set; }

            /// <summary>
            /// 正文是否是html格式
            /// </summary>
            public bool isbodyHtml { get; set; }

            /// <summary>
            /// 附件
            /// </summary>
            public string[] attachmentsPath { get; set; }

            public bool Send()
            {
                //使用指定的邮件地址初始化MailAddress实例
                MailAddress maddr = new MailAddress(mailFrom);
                //初始化MailMessage实例
                MailMessage myMail = new MailMessage();


                //向收件人地址集合添加邮件地址
                if (mailToArray != null)
                {
                    for (int i = 0; i < mailToArray.Length; i++)
                    {
                        myMail.To.Add(mailToArray[i].ToString());
                    }
                }

                //向抄送收件人地址集合添加邮件地址
                if (mailCcArray != null)
                {
                    for (int i = 0; i < mailCcArray.Length; i++)
                    {
                        myMail.CC.Add(mailCcArray[i].ToString());
                    }
                }
                //发件人地址
                myMail.From = maddr;

                //电子邮件的标题
                myMail.Subject = mailSubject;

                //电子邮件的主题内容使用的编码
                myMail.SubjectEncoding = Encoding.UTF8;

                //电子邮件正文
                myMail.Body = mailBody;

                //电子邮件正文的编码
                myMail.BodyEncoding = Encoding.Default;

                myMail.Priority = MailPriority.High;

                myMail.IsBodyHtml = isbodyHtml;

                //在有附件的情况下添加附件
                try
                {
                    if (attachmentsPath != null && attachmentsPath.Length > 0)
                    {
                        Attachment attachFile = null;
                        foreach (string path in attachmentsPath)
                        {
                            attachFile = new Attachment(path);
                            myMail.Attachments.Add(attachFile);
                        }
                    }
                }
                catch (Exception err)
                {
                    throw new Exception("在添加附件时有错误:" + err);
                }

                SmtpClient smtp = new SmtpClient();
                //指定发件人的邮件地址和密码以验证发件人身份
                smtp.Credentials = new System.Net.NetworkCredential(mailFrom, mailPwd);


                //设置SMTP邮件服务器
                smtp.Host = host;
                smtp.EnableSsl = true;
                try
                {
                    //将邮件发送到SMTP邮件服务器
                    smtp.Send(myMail);
                    return true;

                }
                catch (System.Net.Mail.SmtpException)
                {
                    return false;
                }

            }
        }

有上面这个类，直接调用Send访问就好了

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

至此就完成邮件发送功能了，快试试吧
