Question

我的网络应用程序调用外部DLL。在dll中我想访问system.net/mailSettings/smtp部分中的specifiedPickupDirectory pickupDirectoryLocation值。如何从dll代码中获取它？

像

这样的东西

System.Configuration.ConfigurationSettings.GetConfig("configuration/system.net/mailSettings/smtp/specifiedPickupDirectory/pickupDirectoryLocation")

但这不起作用

Answer 1

您可以使用：

public string GetPickupDirectory()
{
    var config = ConfigurationManager.GetSection("system.net/mailSettings/smtp") as SmtpSection;

    return (config != null) ? config.SpecifiedPickupDirectory : null;
}

Answer 2

我想你可以简单地使用PickupDirectoryLocation属性。

// if .NET 4.0 don't forget that SmtpClient is IDisposable
SmtpClient client = new SmtpClient();
string pickupLocation = client.PickupDirectoryLocation;

通过这种方式，您不会在代码中使用魔术字符串，如果在框架的未来版本中此属性更改配置文件中的名称或位置，则不必担心。

Answer 3

使用它：

using System.Configuration;
using System.Web.Configuration;
using System.Net.Configuration;

然后：

Configuration config = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
MailSettingsSectionGroup settings = (MailSettingsSectionGroup)config.GetSectionGroup("system.net/mailSettings");

然后你就可以访问

了

//settings.Smtp.SpecifiedPickupDirectory;

当然，这也应该在System.Net.Mail.SmtpClient.PickupDirectoryLocation属性中找到

C＃从外部dll中读取web.config中的<system.net> <mailsettings> </mailsettings> </system.net>
