调用发送邮件的方法:
static void Main(string[] args)
{
//获得各种参数，不需要的用空字符串
string path = Directory.GetCurrentDirectory();
string file = path + @"\Excel.xlsx"; //附件1
string file2 = path + @"\Excel2.xlsx";//附件2
string smtpServer = "smtp.163.com";//163邮箱的smtp服务器
int port = 25;//端口
string mailFrom = "******@163.com";//发件人邮箱
string pwd = "*********";//密码
string mailTo = "123@163.com,456@qq.com";//收件人邮箱,多个用户用逗号隔开
string mailCC = "";//抄送人,多个用户用逗号隔开
string mailBcc = "";//密送
string mailSubject = "测试邮件";//主题
string mailContent = "HI,这是我发给你的一个测试邮件";//内容
string ah = file+","+file2; //附件-文件路径
if (EmailHelper.SendEmail(smtpServer, port, mailFrom, pwd, mailTo, mailCC, mailBcc, mailSubject, mailContent, ah) == true)
{
Console.WriteLine("发送成功!");
}
else
Console.WriteLine("发送失败");
Console.ReadKey();
}
注意:
- 确认发件人的邮箱已开通smtp;
- 对应邮箱的smtp填写正确，例:126邮箱:smtp@126.com
- 对应的邮箱SendEmail 中是否要使用SSL加密连接
