Visual C#中使用Gmail发送邮件

主要是设置Gmail的SMTP地址，端口，SSL加密等参数，代码如下：

private void button1_Click(object sender, EventArgs e)
{
MailMessage msg = new System.Net.Mail.MailMessage();
msg.To.Add("xxx@sina.com");
msg.CC.Add("zzz@gmail.com");

msg.From = new MailAddress("yyy@gmail.comm", "yyy", System.Text.Encoding.UTF8);
msg.Subject = "这是测试邮件";
msg.SubjectEncoding = System.Text.Encoding.UTF8;
msg.Body = "邮件内容";
msg.BodyEncoding = System.Text.Encoding.UTF8;
msg.IsBodyHtml = false;
msg.Priority = MailPriority.High;

SmtpClient client = new SmtpClient();
//设置GMail邮箱和密码
client.Credentials = new System.Net.NetworkCredential("yyy@gmail.com", "xxxxxx");
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
object userState = msg;
try
{
client.Send(msg);
MessageBox.Show("发送成功");
}
catch (System.Net.Mail.SmtpException ex)
{
MessageBox.Show(ex.Message, "发送邮件出错");
}
}
