一、首先需要配置web.config文件：


<system.net>
<mailSettings>
<smtp from="Emailname">

<!--这里的host是你本人的邮箱所在服务器,如新浪就会是smtp.sina.com,

userName为你的邮箱名称,password为你的邮箱密码-->
<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：[email protected]</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：[email protected]</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);
System.Net.Mail.MailAddress to = new System.Net.Mail.MailAddress(mailto);//如[email protected]
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.ToString());
mail.Attachments.Add(data);
}
mySmth.Send(mail);
mail.Dispose();
return true;
}
catch
{
return false;
}
}
