在ASP.net中单击按钮后发送电子邮件C＃

嗨，我想在按钮点击Asp.net后发送电子邮件。

将从查询中检索发送电子邮件的电子邮件。

string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; SqlDataReader reader; string sendMessage = "SELECT aspnet_Membership.Email FROM aspnet_Membership join User_Profile on User_Profile.UserId = aspnet_Membership.UserId JOIN Project_List on Project_List.ProfileId = User_Profile.ProfileId WHERE Project_List.ProfileId = 1"; using (SqlConnection myConnection = new SqlConnection(connectionString)) { myConnection.Open(); SqlCommand myCommand = new SqlCommand(sendMessage, myConnection); ArrayList emailArray = new ArrayList(); reader = myCommand.ExecuteReader(); while (reader.Read()) { emailArray.Add(reader["email"]); } foreach (string email in emailArray) 

它没有出现任何错误，我也没有收到任何电子邮件

这段代码应该有效：

 foreach(string email in emailArray) { SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587); smtp.UseDefaultCredentials = false; smtp.Credentials = new NetworkCredential("[e-mail]", "xxxxxxxxx"); smtp.EnableSsl = true; MailMessage msg = new MailMessage("[e-mail]", email); msg.Subject = "Test1"; msg.Body = "Test2"; smtp.Send(msg); } 

您应该在gmail帐户中关闭安全设置。

编辑：就像我说你应该关闭Gmail帐户中的安全设置！ 如果此链接无法帮助您只是谷歌exception！ 检查链接 ！ 或者这个链接
