  北大青鸟武汉宏鹏鲁广校区老师解读:.Net使用SmtpClient发送邮件

  从网上找了一个封装。Net的Smtp邮件发送的类

  [csharp]

  class MailSender

  {

198彩票官网   private MailMessage mailMessage;

198彩票官网   private SmtpClient smtpClient;

  private string password;//发件人密码

  ///

  /// 发件人地址

  /// 邮件正文

  /// 邮件的主题

  /// 发件人密码

198彩票官网   public MailSender(string To, string From, string Body, string Title, string Password)

  {

  mailMessage = new MailMessage();

198彩票官网   mailMessage.To.Add(To);

  mailMessage.From = new System.Net.Mail.MailAddress(From);

  mailMessage。Subject = Title;

  mailMessage.Body = Body;

  mailMessage.IsBodyHtml = true;

  mailMessage.BodyEncoding = System.Text.Encoding.UTF8;

  mailMessage.Priority = System.Net.Mail.MailPriority.Normal;

  this.password = Password;

  }

  ///

  /// 添加附件

  ///

  public void Attachments(string Path)

  {

  string[] path = Path.Split(',');

  Attachment data;

  ContentDisposition disposition;

  for (int i = 0; i < path.Length; i++)

  {

  data = new Attachment(path[i], MediaTypeNames.Application.Octet);//实例化附件

  disposition = data。ContentDisposition;

  disposition.CreationDate = System.IO.File.GetCreationTime(path[i]);//获取附件的创建日期

  disposition.ModificationDate = System.IO.File.GetLastWriteTime(path[i]);//获取附件的修改日期

  disposition。ReadDate = System。IO。File。GetLastAccessTime(path[i]);//获取附件的读取日期

  mailMessage。Attachments。Add(data);//添加到附件中

  }

  }

  ///

  smtpClient.Host = "smtp." + mailMessage.From.Host;

198彩票官网   smtpClient.SendCompleted += new SendCompletedEventHandler(CompletedMethod);//注册异步发送邮件完成时的事件

  smtpClient.SendAsync(mailMessage, mailMessage.Body);

  }

  }

198彩票官网   smtpClient.Send(mailMessage);

  }

  }

  }

198彩票官网   使用某些邮箱的时候会报错(如sohu):不允许使用邮箱名称,服务器响应为: xxx.需要设置单独的用户名,故修改了下,并做了一些优化。如下:

  [csharp]

  class MailSender

  {

  private readonly MailMessage mail;

198彩票官网   private readonly string password;//发件人密码

  private readonly string user;

  ///

  /// 处审核后类的实例

  ///

  /// 收件人地址

  /// 发件人地址

  /// 邮件正文

  /// 邮件的主题

  /// 发件人账号

  /// 发件人密码

  public MailSender(string to, string from, string body, string subject, string sendAccount, string sendPassword)

  {

198彩票官网   mail = new MailMessage();

  mail。To。Add(to);

  mail.From = new MailAddress(from);

  mail.Subject = subject;

  mail.Body = body;

  mail.IsBodyHtml = true;

  mail.BodyEncoding = System.Text.Encoding.UTF8;

  mail。Priority = MailPriority。Normal;

198彩票官网   this.password = sendPassword;

  this.user = sendAccount;

  }

  ///

  /// 添加附件

  ///

198彩票官网   public void Attachments(string path)

  {

  string[] pathes = path.Split(',');

  for (int i = 0; i < pathes。Length; i++)

  {

  var data = new Attachment(pathes[i], MediaTypeNames.Application.Octet);//实例化附件

  var disposition = data.ContentDisposition;

  disposition.CreationDate = System.IO.File.GetCreationTime(pathes[i]);//获取附件的创建日期
