通过C#发送邮件，可以根据自己的需求更改。
这个是个配置文件的类，可以用，也可以改，也可以不用。

调用的时候用这个方法
复制代码
private void button1_Click(object sender, EventArgs e)
{
t1 = databind(qishishijian.Value, jieshushijian.Value);
t2 = databind1(qishishijian.Value, jieshushijian.Value);
SendMail.LargeMailBody = "";
try
{
SendMail.SendLargeMsg(t1, "测试内容1);
SendMail.SendLargeMsg(t2, "测试内容2");
SendMail.Mail.SendStrMail("<p style="font-size: 10pt">以下内容为系统自动发送，请勿直接回复，谢谢。
}
catch { MessageBox.Show("没有可以发送的内容！"); }
}
复制代码
我在工作中经常用，大家可以改成自己的。
