正确执行嵌套集的自定义配置节？ [英] Correct implementation of a custom config section with nested collections?
本文介绍了正确执行嵌套集的自定义配置节？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在Web应用程序中，我希望能够通过定义一些映射配置部分是这样的：
In a web application, I want to be able to define some mapping using a config section like this:
<configuration>
<configSections>
<sectionGroup name="MyCustomer">
<section name="CatalogMappings" type="MyCustom.MyConfigSection" />
</sectionGroup>
</configSections>
<MyCustomer>
<catalogMappings>
<catalog name="toto">
<mapping value="1" displayText="titi" />
<mapping value="2" displayText="tata" />
</catalog>
<catalog name="toto2">
<mapping value="1" displayText="titi2" />
<mapping value="2" displayText="tata2" />
</catalog>
</catalogMappings>
</MyCustomer>
</configuration>
我竭力要实现这一目标，我的定义收藏集时尤其如此。什么是我需要执行实现这一目标的课吗？
I'm struggling to achieve this goal, especially when defining my collection of collections. What are the classes that I need to implement to achieve this?
目前，我有：
public class CatalogMappingSection : System.Configuration.ConfigurationSection
{
public class Mapping : ConfigurationElement
{
[ConfigurationProperty("externalKey")]
public string ExternalKey { get; set; }
[ConfigurationProperty("displayText", IsRequired=true)]
public string DisplayText { get; set; }
[ConfigurationProperty("value", IsRequired=true, IsKey=true)]
public int Value { get; set; }
}
public class Catalog : ConfigurationElementCollection
{
[ConfigurationProperty("name", IsRequired=true, IsKey=true)]
public string Name { get; set; }
protected override ConfigurationElement CreateNewElement()
{
return new Mapping();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((Mapping)element).Value;
}
}
public class CatalogCollection : ConfigurationElementCollection
{
[ConfigurationProperty("catalog")]
[ConfigurationCollection(typeof(Catalog))]
public Catalog CatalogMappingCollection
{
get
{
return (Catalog)base["catalog"];
}
}
protected override ConfigurationElement CreateNewElement()
{
return new Catalog();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((Catalog)element).Name;
}
}
[ConfigurationProperty("catalogMappings")]
[ConfigurationCollection(typeof(CatalogCollection))]
public CatalogCollection CatalogMappings
{
get
{
return (CatalogCollection)base["catalogMappings"];
}
}
}
但是，这是行不通的预期。
But, this is not working as expected.
在此先感谢您的帮助。
推荐答案
我终于找到了这家伙的例子。这是$ C $的CD和工作的权利开箱。
I finally found this guy's example. It was coded and worked right out of the box.

我要在这里贴上code ......仅仅是因为当有人说你的答案就在这里我无法忍受，和链接已经死了。
I am going to paste the code here......only because I cannot stand it when someone says "Your answer is here", and the link is dead.
请先试试他的网站，并留下了谢谢，如果它工作。
Please try his website first, and leave a "thank you" if it works.

和配置code
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="TunnelSection" type="SSHTunnelWF.TunnelSection,SSHTunnelWF" />
</configSections>
<TunnelSection>
<host SSHServerHostname="tsg.edssdn.net" username="user" SSHport="22" password="pass" privatekey="" privatekeypassphrase="">
<tunnels>
<tunnel name="tfs" localport="8081" remoteport="8080" destinationserver="tfs2010.dev.com" />
<tunnel name="sql" localport="14331" remoteport="1433" destinationserver="sql2008.dev.com" />
<tunnel name="crm2011app" localport="81" remoteport="80" destinationserver="crm2011betaapp.dev.com" />
</tunnels>
</host>
<host SSHServerHostname="blade16" username="root" SSHport="22" password="pass" privatekey="" privatekeypassphrase="">
<tunnels>
<tunnel name="vnc" localport="5902" remoteport="5902" destinationserver="blade1.dev.com" />
</tunnels>
</host>
</TunnelSection>
</configuration>
然后是呼
TunnelSection tunnels = ConfigurationManager.GetSection("TunnelSection") as TunnelSection
