Asp.net 自动发送邮件的方法

Asp.net 自动发送邮件的方法
今天有一个模块需要自动发送邮件的功能，就随便写了一个，记录一下作为积累。

一、首先需要配置web.config文件：

<system.net>
<mailSettings>
<smtp from="Emailname">
<network host="smtp.163.com" userName="Emailname" password="Emailpassword"
port="25" defaultCredentials="false"/>
</smtp>
</mailSettings>
</system.net>

二、然后编写发送邮件的函数：

//// <summary>
/// 邮件发送方法(带附件)
/// </summary>
/// <param name="mailto">收件人地址。如：receiver@163.com</param>
/// <param name="mailsubject">邮件标题</param>
/// <param name="mailbody">邮件正文</param>
/// <param name="mailFrom">邮件发送人地址。如：sender@163.com</param>
/// <param name="list">附件路径</param>
/// <returns></returns>
public bool MySendMail(string mailto, string mailsubject, string mailbody, string mailFrom, ArrayList list)
{
try
{
//邮件发送人地址
System.Net.Mail.MailAddress from = new System.Net.Mail.MailAddress(mailFrom);
//如test@163.com,初步测试，用test@sina.com不行，用163的邮件服务器，就必须用163邮箱的用户名
//收件人地址
System.Net.Mail.MailAddress to = new System.Net.Mail.MailAddress(mailto);//如test@tom.com
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage(from, to);
mail.Subject = mailsubject;
mail.Body = mailbody;
//以下设置服务器
System.Net.Mail.SmtpClient mySmth = new System.Net.Mail.SmtpClient();
//以下为增加附件
int count = list.Count;
for (int i = 0; i < count; i++)
{
System.Net.Mail.Attachment data = new System.Net.Mail.Attachment(list[i].ToString());
mail.Attachments.Add(data);
}
mySmth.Send(mail);
mail.Dispose();
return true;
}
catch
{
return false;
}
}

三、最后就是对函数的调用了：

//自动发送邮件
string mailSubject = "会员注册确认函";
string mailBody = "正文内容。";
string mailFrom = ConfigurationManager.AppSettings["SendMail"];
ArrayList List = new ArrayList();
List.Add(Server.MapPath(ConfigurationManager.AppSettings["SendMailText"]));
if (MySendMail(this.txtEmail.Text, mailSubject, mailBody, mailFrom, List))
{
...
//发送成功，进行相应处理
}
else
{
...
//发送失败，进行相应处理
return;
}
