从web.config中的asp.net smtp客户端配置中获取“from”属性值

Question

如何从web.config文件中的asp.net SMTP客户端配置中获取“from”属性值？

<mailSettings>
  <smtp deliveryMethod="Network" from="administrator@somewebsite.com">
    <network host="somehosting" userName="someusername" password="somepassword"/>
  </smtp>
</mailSettings>

Answer 1

像这样：

var mailSettings = (MailSettingsSectionGroup)WebConfigurationManager.GetSection("system.net/mailSettings");
string from = mailSettings.From;

Answer 2

另一种方法是使用命名部分：

应用程序配置：

<configuration>
  <configSections>
   <sectionGroup name="mailSettings">
    <section name="DefaultSmtpProvider" type="System.Net.Configuration.SmtpSection"/>
   </sectionGroup>
  </configSections>

 <mailSettings>
  <DefaultSmtpProvider from="YourAddress@YourDomain.com">
   <network host="@host" userName="@userName" password="@password" defaultCredentials ="false" />
  </DefaultSmtpProvider>
 </mailSettings>
</configuration>

初始代码：

SmtpSection smtpSettings = (SmtpSection)ConfigurationManager.GetSection("mailSettings/DefaultSmtpProvider");
var message= new MailMessage(smtpSettings.From, recipientAddress};

这也允许您在一个配置中有多个smtp设置，以防您需要切换smtpClients。我忘了陈述，如果使用这种方法，你必须手动建立smtp客户端：

new SmtpClient
        {
            DeliveryMethod = smtpSettings.DeliveryMethod,
            Host = smtpSettings.Network.Host,
            UseDefaultCredentials = smtpSettings.Network.DefaultCredentials,
            Credentials = new NetworkCredential(smtpSettings.Network.UserName, smtpSettings.Network.Password)
        };
