C# AppSettings: Есть ли простой способ поместить набор в <appSetting>
Не уверенный точно, в чем Вы нуждаетесь. Ниже извлечение из одного из моих lo4net.config файлов:
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<param name="File" value="App_Data\log"/>
<param name="DatePattern" value=".yyyy-MM-dd-tt".log""/>
<param name="AppendToFile" value="true"/>
<param name="RollingStyle" value="Date"/>
<param name="StaticLogFileName" value="false"/>
<param name="maxSizeRollBackups" value="60" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%r %d [%t] %-5p %c - %m%n"/>
</layout>
</appender>

I have dealt a similar issue and I did it with this code. Hope this helps in your problem.
In this case List (similar to my URLSection) will have a full configuration Section in web.config which you can get all values from this section then.
<configSections>
<section name="URLSection" type="A.WebConfigSection,A,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null"/>
</configSections>
<appSettings></appSettings>
<URLSection>
<urlCollection>
<add url="1" value="a"/>
<add url="2" value="b"/>
</urlCollection>
</URLSection>
I made three classes for this: ConfigElement, ConfigElementCollection, WebConfigSection.
ConfigElement
using System;
using System.Collections.Generic;
using System.Text;
using System.Configuration;
namespace A
{
public class ConfigElement:System.Configuration.ConfigurationElement
{
[ConfigurationProperty("url",IsRequired=true) ]
public string url
{
get
{
return this["url"] as string;
}
}
[ConfigurationProperty("value", IsRequired = true)]
public string value
{
get
{
return this["value"] as string;
}
}
}
}
ConfigElementCollection
using System;
using System.Collections.Generic;
using System.Text;
using System.Configuration;
namespace A
{
public class ConfigElementCollection:ConfigurationElementCollection
{
public ConfigElement this[int index]
{
get
{
return base.BaseGet(index) as ConfigElement;
}
}
protected override ConfigurationElement CreateNewElement()
{
return new ConfigElement();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((ConfigElement)(element)).url;
}
}
}
WebConfigSection
using System;
using System.Collections.Generic;
using System.Text;
using System.Configuration;
namespace A
{
public class WebConfigSection:ConfigurationSection
{
public WebConfigSection()
{
}
[ConfigurationProperty("urlCollection")]
public ConfigElementCollection allValues
{
get
{
return this["urlCollection"] as ConfigElementCollection;
}
}
public static WebConfigSection GetConfigSection()
{
return ConfigurationSettings.GetConfig("URLSection") as WebConfigSection;
}
}
}
You'd likely be better off putting this information in a separate XML file and having a reference to that file in AppSettings. That would give you a lot more flexibility around how you retrieved the information and consumed it.
The only thing would be that you'd want to create a separate (static?) class for reading the XML in a similar fashion to the System.Configuration.ConfigurationManager.AppSettings class.
If, on the other hand, it HAD to be in your Web.Config file, I would suggest the only way to achieve this simply would be to have a [pipe/comma/semi-colon] delimited array in one "List" setting.
