Question

求一个能借鉴的使用C#编写的邮件发送功能的源码

最好有详细注释,十分感谢

Answer 1

给你一个最简洁的，绝对能用！
首先面板上添加一个【Button按钮】把代码粘贴到单击事件中！
代码如下：
try
{
SmtpClient client = new SmtpClient("smtp.sina.com");//用哪里的邮箱发邮件就写哪里的smtp就好了，这个是新浪的
client.UseDefaultCredentials = false;
//百度知道ID:Mr_点耐特 提供
client.Credentials = new System.Net.NetworkCredential("发件箱账号","发件箱密码");//发送邮箱的用户名.发送邮箱的密码
client.DeliveryMethod = SmtpDeliveryMethod.Network;
MailMessage mail = new MailMessage();
mail.From = new MailAddress("xxxxxx@sina.com");//这里是收件箱
mail.To.Add("xxx@sina.com");//抄送给谁，可以不填
mail.Subject = "邮件的标题";
//百度知道ID:Mr_点耐特 提供
mail.BodyEncoding = System.Text.Encoding.Default;
mail.Body = "邮件的内容";
mail.IsBodyHtml = true;
client.Send(mail);
MessageBox.Show("<script>alert('发送成功');</script>");//成功提示
//百度知道ID:Mr_点耐特 提供
}
catch (Exception ex)
{
MessageBox.Show("<script>alert('" + ex.Message + "');</script>");//错误提示
}
亲测过了~...就是自己写的......
你把邮件地址，标题，内容都用TextBox代替就成了！
我这样写是为了方便你去验证可用性！！！
