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);
}
}
///

smtpClient.Send(mailMessage);
}
}
}
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;
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

/// 发件人密码
public MailSender(string to, string from, string body, string subject, string sendAccount, string sendPassword)
{
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;
this.password = sendPassword;
this.user = sendAccount;
}
///
/// 添加附件
///
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
disposition.ModificationDate = System.IO.File.GetLastWriteTime(pathes[i]);//获取附件的修改日期
disposition.ReadDate = System.IO.File.GetLastAccessTime(pathes[i]);//获取附件的读取日期
mail.Attachments.Add(data);//添加到附件中
}
}
