Hi,
Try the below code,
Configuration configurationFile = WebConfigurationManager
.OpenWebConfiguration("~/web.config");
MailSettingsSectionGroup mailSettings = configurationFile
.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;
if (mailSettings != null)
{
int port = mailSettings.Smtp.Network.Port;
string host = mailSettings.Smtp.Network.Host;
string password = mailSettings.Smtp.Network.Password;
string username = mailSettings.Smtp.Network.UserName;
}
or can also use,
Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
Hope this helps.
