Accessing SMTP Mail Settings from Web.Config File by using c#

Need to read my SMTP email settings defined under system.net section in my web.config file.

Below is one example of SMTP email setting defined in web.co开发者_JAVA百科nfig file: (Under Section)

<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="testuser@domail.com">
<network defaultCredentials="true" host="localhost" port="25" userName="user” password="testPassword"/>
</smtp>
</mailSettings>
</system.net>

How to Access the SMTP Mail Setting by using c#

Just use the System.Net.Mail classes to send your e-mails. It will automagically pick-up the Mail setting from your web.config.

You can use the WebConfigurationManager:

Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
MailSettingsSectionGroup mailSettings = configurationFile.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;

Response.Write(mailSettings.Smtp.Network.Host);

Configuration config;

bool isWebApp = HttpRuntime.AppDomainAppId != null;

if (isWebApp)
{
    config = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
}
else
{
    config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
}

var mailSettings = config.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;    

You can use this code

Response.Write(ConfigurationManager.GetSection("system.net/mailSettings/smtp").Network.UserName)
Response.Write(ConfigurationManager.GetSection("system.net/mailSettings/smtp").Network.Host)
Response.Write(ConfigurationManager.GetSection("system.net/mailSettings/smtp").Network.Password)
