C#调用QQ_Mail发送邮件实例代码两例
代码案例一:
private void button1_Click(object sender, EventArgs e) { string myMaillAdress = ""; string myMaillPassword = ""; string myMaillMessage = ""; string toMaillAdress = ""; QQEmail qq_mial = new QQEmail(); bool send_status = qq_mial.IsSendEmail(myMaillAdress, toMaillAdress, myMaillMessage, myMaillPassword); } class QQEmail { public bool IsSendEmail(string FromAddress, string ToAddress, string Message, string Pwd) { MailAddress Address = new MailAddress(FromAddress); MailMessage mail = new MailMessage(); mail.SubjectEncoding = System.Text.Encoding.UTF8; mail.Subject = "这是" + FromAddress + "发送的一段信息:"; mail.BodyEncoding = System.Text.Encoding.UTF8; mail.Body = Message; mail.IsBodyHtml = true; mail.Priority = System.Net.Mail.MailPriority.Low; mail.To.Add(ToAddress); mail.From = Address; SmtpClient smtp = new SmtpClient("smtp.qq.com", 25);//smtp支持的服务器是smtp.qq.com,服务器端口是25,587也行 smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; smtp.EnableSsl = true; smtp.UseDefaultCredentials = false; smtp.Credentials = new System.Net.NetworkCredential(FromAddress, Pwd);//切记这两个数据一定要填对 try { smtp.Send(mail); return true; } catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message); return false; } } }
代码案例二:
using log4net; using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.Mail; using System.Net.Security; using System.Security.Cryptography.X509Certificates; using System.Text; namespace BLL { public class emailHandle { private string _serviceType = "SMTP"; private string _host; /// <summary> /// 发送者邮箱 /// </summary> public string From { get; set; } /// <summary> /// 接收者邮箱列表 /// </summary> public List<string> To { get; set; } /// <summary> /// 抄送者邮箱列表 /// </summary> public string[] Cc { get; set; } /// <summary> /// 秘抄者邮箱列表 /// </summary> public string[] Bcc { get; set; } /// <summary> /// 邮件主题 /// </summary> public string Subject { get; set; } /// <summary> /// 邮件内容 /// </summary> public string Body { get; set; } /// <summary> /// 是否是HTML格式 /// </summary> public bool IsBodyHtml { get; set; } /// <summary> /// 附件列表 /// </summary> public string[] Attachments { get; set; } /// <summary> /// 邮箱服务类型(Pop3,SMTP,IMAP,MAIL等),默认为SMTP /// </summary> public string ServiceType { get { return _serviceType; } set { _serviceType = value; } } /// <summary> /// 邮箱服务器,如果没有定义邮箱服务器,则根据serviceType和Sender组成邮箱服务器 /// </summary> public string Host { get { return _host; } set { _host = value; } } /// <summary> /// 邮箱账号(默认为发送者邮箱的账号) /// </summary> public string UserName { get; set; } /// <summary> /// 邮箱密码(默认为发送者邮箱的密码),默认格式GB2312 /// </summary> public string Password { get; set; } /// <summary> /// 邮箱优先级 /// </summary> public MailPriority MailPriority { get; set; } /// <summary> /// 邮件正文编码格式 /// </summary> public Encoding Encoding { get; set; } /// <summary> /// 构造参数,发送邮件,使用方法备注:公开方法中调用 /// </summary> public int Send() { var mailMessage = new MailMessage(); //读取To 接收者邮箱列表 try { if (this.To != null && this.To.Count > 0) { foreach (string to in this.To) { if (string.IsNullOrEmpty(to)) continue; mailMessage.To.Add(new MailAddress(to.Trim())); } } //读取Cc 抄送者邮件地址 if (this.Cc != null && this.Cc.Length > 0) { foreach (var cc in this.Cc) { if (string.IsNullOrEmpty(cc)) continue; mailMessage.CC.Add(new MailAddress(cc.Trim())); } } //读取Attachments 邮件附件 if (this.Attachments != null && this.Attachments.Length > 0) { foreach (var attachment in this.Attachments) { if (string.IsNullOrEmpty(attachment)) continue; mailMessage.Attachments.Add(new Attachment(attachment)); } } //读取Bcc 秘抄人地址 if (this.Bcc != null && this.Bcc.Length > 0) { foreach (var bcc in this.Bcc) { if (string.IsNullOrEmpty(bcc)) continue; mailMessage.Bcc.Add(new MailAddress(bcc.Trim())); } } //读取From 发送人地址 mailMessage.From = new MailAddress(this.From); //邮件标题 Encoding encoding = Encoding.GetEncoding("GB2312"); mailMessage.Subject = this.Subject; //邮件正文是否为HTML格式 mailMessage.IsBodyHtml = this.IsBodyHtml; //邮件正文 mailMessage.Body = this.Body; mailMessage.BodyEncoding = this.Encoding; //邮件优先级 mailMessage.Priority = this.MailPriority; //发送邮件代码实现 var smtpClient = new SmtpClient { Host = this.Host, EnableSsl = true, Credentials = new NetworkCredential(this.UserName, this.Password) }; //加这段之前用公司邮箱发送报错:根据验证过程,远程证书无效 //加上后解决问题 ServicePointManager.ServerCertificateValidationCallback = delegate(Object obj, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors) { return true; }; //认证 smtpClient.Send(mailMessage); return 1; } catch (Exception ex) { var loger = LogManager.GetLogger(typeof(emailHandle)); loger.Info(string.Format("发送邮件异常,收信邮箱:{0}", this.To[0]), ex); return -1; } } } }
