从网上找了一个封装.Net的Smtp邮件发送的类

[csharp]

class MailSender

{

private MailMessage mailMessage;

private SmtpClient smtpClient;

private string password;//发件人密码

///

/// 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

/// 发件人密码

public MailSender(string To, string From, string Body, string Title, string Password)

{

mailMessage = new MailMessage();

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

}

}

///

/// 异步发送邮件

///

///

public void SendAsync(SendCompletedEventHandler CompletedMethod)

{

if (mailMessage != null)

{

smtpClient = new SmtpClient();

smtpClient.Credentials = new System.Net.NetworkCredential(mailMessage.From.Address, password);//设置发件人身份的票据

smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;

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

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

smtpClient.SendAsync(mailMessage, mailMessage.Body);

}

}

///

/// 发送邮件

///

public void Send()

{

if (mailMessage != null)

{

smtpClient = new SmtpClient();

smtpClient.Credentials = new System.Net.NetworkCredential(mailMessage.From.Address, password);//设置发件人身份的票据

smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;

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

smtpClient.Send(mailMessage);

}

}

}
