protected void Button1_Click(object sender, EventArgs e)
{
    MailMessage message = new MailMessage()
    {
        Subject = "Subject",
        Body = "Body"
    };
    message.To.Add(new MailAddress("[email protected]", "Some name"));

    SmtpClient client = new SmtpClient();
    client.EnableSsl = true;
    client.Send(message);
}

配置

<configuration>
  <system.net>
    <mailSettings>
      <smtp from="[email protected]">
        <network host="****" defaultCredentials="false"  port="587" userName="****" password="****" />
      </smtp>
    </mailSettings>
  </system.net>
 <system.web>

修正。现在可以了。谢谢马雷克

您的问题可能是 defaultCredentials 设置为 true。尝试将其设置为 false，然后重试。另外，为什么要在代码中再次设置凭据？ Gmail 还要求通过 SSL（如果我没记错的话）在端口 587 上发送电子邮件。

就在今天，我在代码中实现了 gmail smtp。我的设置和代码：

<system.net>
    <mailSettings>
      <smtp deliveryMethod="Network" from="MY_GMAIL_EMAIL">
        <network defaultCredentials="false" host="smtp.gmail.com" port="587" userName="MY_GMAIL_USERNAME" password="MY_GMAIL_PASSWORD" />
      </smtp>
    </mailSettings>
  </system.net>


MailMessage message = new MailMessage() {
                              Subject = "Subject",
                              Body = "Body"
                          };
message.To.Add(new MailAddress("[email protected]", "Some name"));
SmtpClient smtpClient = new SmtpClient();
smtpClient.EnableSsl = true;
smtpClient.Send(message);

Your problem might be with defaultCredentials set to true. Try setting that to false and try again. Also, why are you setting your credentials again in code? Gmail also requires emails to be sent via SSL (if I remember correctly) on port 587.

Just today I implemented gmail smtp in my code. My settings and code:

<system.net>
    <mailSettings>
      <smtp deliveryMethod="Network" from="MY_GMAIL_EMAIL">
        <network defaultCredentials="false" host="smtp.gmail.com" port="587" userName="MY_GMAIL_USERNAME" password="MY_GMAIL_PASSWORD" />
      </smtp>
    </mailSettings>
  </system.net>


MailMessage message = new MailMessage() {
                              Subject = "Subject",
                              Body = "Body"
                          };
message.To.Add(new MailAddress("[email protected]", "Some name"));
SmtpClient smtpClient = new SmtpClient();
smtpClient.EnableSsl = true;
smtpClient.Send(message);
