C#使用MailAddress类发送html格式邮件的实例代码
1.首先引入命名空间using system.net.mail;
2.将发送的邮件的功能封装成一个类,该类中包含了发送邮件的基本功能:收件人(多人),抄送(多人),发送人,主题,邮件正文,附件等,封装的email类如下:
public class email
{
/// <summary>
/// 发送者
/// </summary>
public string mailfrom { get; set; }
/// <summary>
/// 收件人
/// </summary>
public string[] mailtoarray { get; set; }
/// <summary>
/// 抄送
/// </summary>
public string[] mailccarray { get; set; }
/// <summary>
/// 标题
/// </summary>
public string mailsubject { get; set; }
/// <summary>
/// 正文
/// </summary>
public string mailbody { get; set; }
/// <summary>
/// 发件人密码
/// </summary>
public string mailpwd { get; set; }
/// <summary>
/// smtp邮件服务器
/// </summary>
public string host { get; set; }
/// <summary>
/// 正文是否是html格式
/// </summary>
public bool isbodyhtml { get; set; }
/// <summary>
/// 附件
/// </summary>
public string[] attachmentspath { get; set; }
public bool send()
{
//使用指定的邮件地址初始化mailaddress实例
mailaddress maddr = new mailaddress(mailfrom);
//初始化mailmessage实例
mailmessage mymail = new mailmessage();
//向收件人地址集合添加邮件地址
if (mailtoarray != null)
{
for (int i = 0; i < mailtoarray.length; i++)
{
mymail.to.add(mailtoarray[i].tostring());
}
}
//向抄送收件人地址集合添加邮件地址
if (mailccarray != null)
{
for (int i = 0; i < mailccarray.length; i++)
{
mymail.cc.add(mailccarray[i].tostring());
}
}
//发件人地址
mymail.from = maddr;
//电子邮件的标题
mymail.subject = mailsubject;
//电子邮件的主题内容使用的编码
mymail.subjectencoding = encoding.utf8;
//电子邮件正文
mymail.body = mailbody;
//电子邮件正文的编码
mymail.bodyencoding = encoding.default;
mymail.priority = mailpriority.high;
mymail.isbodyhtml = isbodyhtml;
//在有附件的情况下添加附件
try
{
if (attachmentspath != null && attachmentspath.length > 0)
{
attachment attachfile = null;
foreach (string path in attachmentspath)
{
attachfile = new attachment(path);
mymail.attachments.add(attachfile);
}
}
}
catch (exception err)
{
throw new exception("在添加附件时有错误:" + err);
}
smtpclient smtp = new smtpclient();
//指定发件人的邮件地址和密码以验证发件人身份
smtp.credentials = new system.net.networkcredential(mailfrom, mailpwd);
//设置smtp邮件服务器
smtp.host = host;
try
{
//将邮件发送到smtp邮件服务器
smtp.send(mymail);
return true;
}
catch (system.net.mail.smtpexception ex)
{
return false;
}
}
}
3.页面调用发送邮件的类
protected void send_click(object sender, eventargs e)
{
email email = new email();
email.mailfrom = "发送人的邮箱地址";
email.mailpwd = "发送人邮箱的密码";
email.mailsubject = "邮件主题";
email.mailbody = "邮件内容";
email.isbodyhtml = true; //是否是html
email.host = "smtp.126.com";//如果是qq邮箱则:smtp:qq.com,依次类推
email.mailtoarray = new string[] { "******@qq.com","12345678@qq.com"};//接收者邮件集合
email.mailccarray = new string[] { "******@qq.com" };//抄送者邮件集合
if (email.send())
{
response.write("<script type='text/javascript'>alert('发送成功!');history.go(-1)</script>");//发送成功则提示返回当前页面;
}
else
{
response.write("<script type='text/javascript'>alert('发送失败!');history.go(-1)</script>");
}
}
