你需要像这样设置NetworkCredential。

client.Credentials = new NetworkCredential（“username”，“password”）;

您的代码应该是这样的。

    MailMessage myMessage = new MailMessage();
    myMessage.Subject = "Test Message";
    myMessage.Body = "Hello World";
    myMessage.From = new MailAddress("willrathlou3@gmail.com", "Will");
    myMessage.To.Add(new MailAddress("willrathlou3@gmail.com", "Will"));

    SmtpClient mySmtpClient = new SmtpClient("smtp.gmail.com");
    mySmtpClient .Credentials=new NetworkCredential("username", "password");

    mySmtpClient.Send(myMessage);

Gmail Smtp消息无法发送。
