          passw = tbPASSWORD.Text;
          string smtpAddress =" smtp.gmail.com" ;;
          int portNumber = 587;
          bool enableSSL = true;
          string emailFromAddress = email; //发件人电子邮件地址
          string password = passw; //发件人密码
          string emailToAddress = email; //收件人电子邮件地址
          string subject =" Hello";
          string body ="你好，这是使用gmail的电子邮件发送测试。" ;;
         使用（MailMessage mail = new MailMessage（））
          {
              mail.From = new MailAddress（emailFromAddress）;
              mail.To.Add（emailToAddress）;
              mail.Subject = subject;
              mail.Body = body;
              mail.IsBodyHtml = true;
              //mail.Attachments.Add(new Attachment（" D：\\TestFile.txt"））; // - 取消注释以发送任何附件
             使用（SmtpClient smtp = new SmtpClient（smtpAddress，portNumber））
              {
                  smtp.Credentials = new NetworkCredential（emailFromAddress，password）;
                  smtp.EnableSsl = enableSSL;
                  smtp.Send（mail）;
              }¥b $ b           }
email = tbFROM.Text;
passw = tbPASSWORD.Text;
string smtpAddress = "smtp.gmail.com";
int portNumber = 587;
bool enableSSL = true;
string emailFromAddress = email; //Sender Email Address
string password = passw; //Sender Password
string emailToAddress = email; //Receiver Email Address
string subject = "Hello";
string body = "Hello, This is Email sending test using gmail.";
using (MailMessage mail = new MailMessage())
{
mail.From = new MailAddress(emailFromAddress);
mail.To.Add(emailToAddress);
mail.Subject = subject;
mail.Body = body;
mail.IsBodyHtml = true;
//mail.Attachments.Add(new Attachment("D:\\TestFile.txt"));//--Uncomment this to send any attachment
using (SmtpClient smtp = new SmtpClient(smtpAddress, portNumber))
{
smtp.Credentials = new NetworkCredential(emailFromAddress, password);
smtp.EnableSsl = enableSSL;
smtp.Send(mail);
}
}
以下一个也无法发送电子邮件
one below also fails to send email
          email = tbFROM.Text;
          passw = tbPASSWORD.Text;
          // MailMessage mail = new MailMessage（tbFROM.Text，tbTO.Text，tbSUBJECT.Text，rtbBODY.Text）;
          MailMessage mail = new MailMessage（电子邮件，电子邮件，电子邮件，电子邮件）;
          SmtpClient smtpClient =新的SmtpClient（"smtp.gmail.com"）;
          smtpClient.Port = 587;
          //smtpClient.Credentials = new NetworkCredential（tbUSERNAME.Text，tbPASSWORD.Text）;
          smtpClient.Credentials = new NetworkCredential（email，passw）;
          smtpClient.EnableSsl = true;
          smtpClient.Send（mail）;
email = tbFROM.Text;
passw = tbPASSWORD.Text;
//MailMessage mail = new MailMessage(tbFROM.Text,tbTO.Text,tbSUBJECT.Text,rtbBODY.Text);
MailMessage mail = new MailMessage(email,email,email,email);
SmtpClient smtpClient = new SmtpClient("smtp.gmail.com");
smtpClient.Port = 587;
//smtpClient.Credentials = new NetworkCredential(tbUSERNAME.Text,tbPASSWORD.Text);
smtpClient.Credentials = new NetworkCredential(email,passw);
smtpClient.EnableSsl = true;
smtpClient.Send(mail);
google无法回复...如何发送电子邮件？
推荐答案
您应该做的第一件事是提供在发送电子邮件失败时收到的错误消息。如果未显示错误消息（应该是），请订阅
SendCompleted事件并检查e.Error。
The first thing you should do is provide the error message received on failure to send an email. If an error message is not presented (which it should be) subscribe to SendCompleted event and inspect e.Error.
登录您的Google电子邮件帐户
关注页面，如果"安全性较低的应用访问权限"关闭，尝试将此设置设置为开，然后重新尝试发送电子邮件。
Login to your Google email account to the follow page, if "Less secure app access" is off, try setting this setting to on then reattempt to send an email.
另请参阅"允许安全性较低的应用程序有什么危险"。
