今天在做发送邮件功能时,开始用qq邮箱和163邮箱都可以正常发送,后再改用我公司的邮箱和smtp时竟然报错了。 异常提示-----“根据验证过程,远程证书无效”,后来通过查询资料解决该问题,上代码: 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; ///
/// 发送者邮箱 /// public string From { get; set; } ///
/// 接收者邮箱列表 /// public List
To { get; set; } /// /// 抄送者邮箱列表 /// public string[] Cc { get; set; } /// /// 秘抄者邮箱列表 /// public string[] Bcc { get; set; } /// /// 邮件主题 /// public string Subject { get; set; } /// /// 邮件内容 /// public string Body { get; set; } /// /// 是否是HTML格式 /// public bool IsBodyHtml { get; set; } /// /// 附件列表 /// public string[] Attachments { get; set; } /// /// 邮箱服务类型(Pop3,SMTP,IMAP,MAIL等),默认为SMTP /// public string ServiceType { get { return _serviceType; } set { _serviceType = value; } } /// /// 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 /// public string Host { get { return _host; } set { _host = value; } } /// /// 邮箱账号(默认为发送者邮箱的账号) /// public string UserName { get; set; } /// /// 邮箱密码(默认为发送者邮箱的密码),默认格式GB2312 /// public string Password { get; set; } /// /// 邮箱优先级 /// public MailPriority MailPriority { get; set; } /// /// 邮件正文编码格式 /// public Encoding Encoding { get; set; } /// /// 构造参数,发送邮件,使用方法备注:公开方法中调用 /// 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; } } } } 本文由职坐标整理并发布,希望对同学们有所帮助。了解更多详情请关注职坐标编程语言C#.NET频道!
