问题描述

我正在尝试使用gmail发送电子邮件，以下是我的代码

I am trying to send email using gmail, below is my code

SmtpClient smtpClient = new SmtpClient();
MailMessage message = new MailMessage();
MailAddress fromAddress = new MailAddress("[e-mail]", "From Me");
MailAddress toAddress = new MailAddress("[e-mail]", "To You");
message.From = fromAddress;
message.To.Add(toAddress);
message.Subject = "Testing!";
message.Body = "This is the body of a sample message";
smtpClient.Host = "smtp.gmail.com";
smtpClient.Credentials = new System.Net.NetworkCredential("username", "password");

smtpClient.EnableSsl = true;


smtpClient.Port = 587;
   
smtpClient.Send(message);

我收到此错误"SMTP服务器需要安全连接或客户端未通过身份验证.服务器响应为:5.5.1需要身份验证."
密码和用户名都是正确的，我尝试了很多事情，但是不起作用:(

您没有在SmtpClient()对象中指定Smtpclient名称.
只需在新SmtpClient()的声明上方添加此行；对象.

字符串服务器="smtp.gmail.com";

并将字符串参数传递给smtpclient对象，如下所示:
SmtpClient smtpClient =新的SmtpClient(服务器);

而不是"SmtpClient smtpClient = new SmtpClient();"

这将起作用..:)

Hi,

You did not specified Smtpclient name in your SmtpClient() object.
Just add this line above the declaration of new SmtpClient(); object.

String server= "smtp.gmail.com";

and pass the string parameter to smtpclient object like this :
SmtpClient smtpClient = new SmtpClient(server);

instead of "SmtpClient smtpClient = new SmtpClient();"

this will work.. :)
