在 C# 中以编程方式从 app.config 访问 system.net 设置

发布于 2024-07-14 15:40:09 字数 746 浏览 6 评论 0原文

我正在尝试以编程方式访问 Windows 应用程序 app.config 文件。特别是，我正在尝试访问“system.net/mailSettings” 以下代码

Configuration config = ConfigurationManager.OpenExeConfiguration(configFileName);

MailSettingsSectionGroup settings = 
    (MailSettingsSectionGroup)config.GetSectionGroup(@"system.net/mailSettings");

Console.WriteLine(settings.Smtp.DeliveryMethod.ToString());

Console.WriteLine("host: " + settings.Smtp.Network.Host + "");
Console.WriteLine("port: " + settings.Smtp.Network.Port + "");
Console.WriteLine("Username: " + settings.Smtp.Network.UserName + "");
Console.WriteLine("Password: " + settings.Smtp.Network.Password + "");
Console.WriteLine("from: " + settings.Smtp.From + "");

未能给出主机，来自。它只获取端口号。其余均为空；

I am trying to programmatically access a Windows application app.config file. In particular, I am trying to access the "system.net/mailSettings"
The following code

Configuration config = ConfigurationManager.OpenExeConfiguration(configFileName);

MailSettingsSectionGroup settings = 
    (MailSettingsSectionGroup)config.GetSectionGroup(@"system.net/mailSettings");

Console.WriteLine(settings.Smtp.DeliveryMethod.ToString());

Console.WriteLine("host: " + settings.Smtp.Network.Host + "");
Console.WriteLine("port: " + settings.Smtp.Network.Port + "");
Console.WriteLine("Username: " + settings.Smtp.Network.UserName + "");
Console.WriteLine("Password: " + settings.Smtp.Network.Password + "");
Console.WriteLine("from: " + settings.Smtp.From + "");

fails to give the host, from. it only gets the port number. The rest are null;

你曾走过我的故事 2024-07-21 15:40:09

这对我来说似乎没问题：

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

if (mailSettings != null)
{
    string smtpServer = mailSettings.Smtp.Network.Host;
}

这是我的 app.config 文件：

<configuration>
  <system.net>
    <mailSettings>
      <smtp>
        <network host="mail.mydomain.com" />
      </smtp>
    </mailSettings>
  </system.net>
</configuration>

但是，正如 Nathan 所说，您可以使用应用程序或计算机配置文件来指定所有 SmtpClient 对象。有关详细信息，请参阅 MDSN 上的元素。

This seems to work ok for me:

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

if (mailSettings != null)
{
    string smtpServer = mailSettings.Smtp.Network.Host;
}

Here's my app.config file:

<configuration>
  <system.net>
    <mailSettings>
      <smtp>
        <network host="mail.mydomain.com" />
      </smtp>
    </mailSettings>
  </system.net>
</configuration>

However, as stated by Nathan, you can use the application or machine configuration files to specify default host, port, and credentials values for all SmtpClient objects. For more information, see <mailSettings> Element on MDSN.

不确定这是否有帮助，但如果您尝试创建 SmtpClient，如果您使用默认构造函数，它将自动使用配置文件中的值。

我使用以下命令来访问邮件设置：

var config = ConfigurationManager.OpenExeConfiguration(
    ConfigurationUserLevel.None);

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

I used the following to access the mailSettings:

var config = ConfigurationManager.OpenExeConfiguration(
    ConfigurationUserLevel.None);

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