调用的时候用这个方法
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。</p>" + SendMail.LargeMailBody);
}
catch { MessageBox.Show("没有可以发送的内容！"); }
}
