在Web应用程序中，我希望能够使用如下配置部分定义一些映射：
<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>
我正在努力实现这一目标，特别是在定义我的馆藏集时。为实现这一目标，我需要实现哪些类？
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，这并没有像预期的那样发挥作用。

我终于找到了这个人的榜样。它被编码并开箱即用。

我要在这里粘贴代码......只是因为当有人说“你的答案在这里”时，我无法忍受它，并且链接已经死了。
请先试试他的网站，如果有效，请留下“谢谢”。

答案 1 :(得分：7)
由于我的其他答案很受欢迎，我使用美国和美国县编写了一个自定义示例。一个更容易理解的例子。
我还添加了一些接口，允许对单元测试进行一些模拟，这是我在撰写原始答案时并不完全清楚的。
我还添加了将设置放在自己的文件中，因此你的app.config文件中没有十亿个东西。
我还添加了一个＆＃34; Finder＆＃34;封装搜索集合中的特定项目。
我还添加了一个自定义枚举。
