How do I change the SMTP port number dynamically in asp.net
Use below method to set dynamic port while sending the email using SMTP
public static void SendMailwithDynamicPort(string strSmtpHost, int strPort, string strMessageBody, string strFrom, string strTo, string strSubject)
{
// Create and configure the smtp client
SmtpClient smtpClient = new SmtpClient();
if (strSmtpHost != null && strSmtpHost.Length > 0)
{
smtpClient.Host = strSmtpHost;
}
smtpClient.Port = strPort; // you can read from config
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
MailMessage mailMessage = new MailMessage();
mailMessage.Body = strMessageBody;
mailMessage.From = new MailAddress(strFrom);
mailMessage.To.Add(strTo);
mailMessage.Subject = strSubject;
mailMessage.Priority = MailPriority.Normal;//to set the email property
smtpClient.Send(mailMessage);
}
or through Web.Config also we can set port number
public static void SendMailwithDynamicPort(string strSmtpHost, int strPort, string strMessageBody, string strFrom, string strTo, string strSubject)
{
// Create and configure the smtp client
SmtpClient smtpClient = new SmtpClient();
if (strSmtpHost != null && strSmtpHost.Length > 0)
{
smtpClient.Host = strSmtpHost;
}
smtpClient.Port = strPort; // you can read from config
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
MailMessage mailMessage = new MailMessage();
mailMessage.Body = strMessageBody;
mailMessage.From = new MailAddress(strFrom);
mailMessage.To.Add(strTo);
mailMessage.Subject = strSubject;
mailMessage.Priority = MailPriority.Normal;//to set the email property
smtpClient.Send(mailMessage);
}
or through Web.Config also we can set port number
<configuration> <!-- Add the email settings to the <system.net> element --> <system.net> <mailSettings> <smtp> <network host="relayServerHostname" port="portNumber" userName="username" password="password" /> </smtp> </mailSettings> </system.net> <system.web> ... </system.web> </configuration>
How to get the users IP those who are accessing your website using asp.net
Use below code to get the IP of your website users:
<%@ Page Language="C#" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Client IP...</title>
<meta http-equiv="Expires" content="-1">
<meta http-equiv="Cache-Control" content="no-cache">
<meta http-equiv="Pragma" content="no-cache">
<%
string _strClientIP = string.Empty;
string[] _strforwardedIpsList;
// Get exact IP address if proxy available
string _strServerVariable = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (!string.IsNullOrEmpty(_strServerVariable))
{
_strforwardedIpsList = _strServerVariable.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
_strClientIP = _strforwardedIpsList[_strforwardedIpsList.Length - 1];
}
else
{
// Get Proxy IP address
_strClientIP = HttpContext.Current.Request.UserHostAddress;
if (string.IsNullOrEmpty(_strClientIP))
_strClientIP = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}
Response.Write(_strClientIP);
%>
