自定义ConfigurationSection

Question

我使用IConfigurationSectionHandler接口来获取有关我的自定义配置节的信息。但是它已经被弃用了，我想用ConfigurationSection代替。

如何使用此视图并使用ConfigurationSection而不是IConfigurationSectionHandler创建自定义ConfigurationSection：

<CustomSectionBlaBla>
   <Parent name="DB">
       <FirstChild value="someValue"/>
       <SecondChild value="someValue"/>
   <Parent/>
    ...
   <Parent name="UI">
       <FirstChild value="someValue"/>
       <SecondChild value="someValue"/>
   <Parent/>
<CustomSectionBlaBla/>

下面是我创建的配置节的一个示例。应该会给你指明正确的方向。

public class ImportConfiguration : ConfigurationSection
{
    [ConfigurationProperty("importMap")]
    public ImportMapElementCollection ImportMap
    {
        get
        {
            return this["importMap"] as ImportMapElementCollection;
        }
    }
}

public class ImportColumnMapElement : ConfigurationElement
{
    [ConfigurationProperty("localName", IsRequired = true, IsKey = true)]
    public string LocalName
    {
        get
        {
            return this["localName"] as string;
        }
        set
        {
            this["localName"] = value;
        }
    }

    [ConfigurationProperty("sourceName", IsRequired = true)]
    public string SourceName
    {
        get
        {
            return this["sourceName"] as string;
        }
        set
        {
            this["sourceName"] = value;
        }
    }
}

public class ImportMapElementCollection : ConfigurationElementCollection
{
    public ImportColumnMapElement this[object key]
    {
        get
        {
            return base.BaseGet(key) as ImportColumnMapElement;
        }
    }

    public override ConfigurationElementCollectionType CollectionType
    {
        get
        {
            return ConfigurationElementCollectionType.BasicMap;
        }
    }

    protected override string ElementName
    {
        get
        {
            return "columnMap";
        }
    }

    protected override bool IsElementName(string elementName)
    {
        bool isName = false;
        if (!String.IsNullOrEmpty(elementName))
            isName = elementName.Equals("columnMap");
        return isName;
    }

    protected override ConfigurationElement CreateNewElement()
    {
        return new ImportColumnMapElement();
    }

    protected override object GetElementKey(ConfigurationElement element)
    {
        return ((ImportColumnMapElement)element).LocalName;
    }
}

下面是它在web.config中的用法：

<importConfiguration>
    <importMap>
        <columnMap localName="PropertyID" sourceName="Detail Number"/>
        <columnMap localName="DateOfOpen" sourceName="Open Date &amp; Time"/>
        <columnMap localName="StartTime" sourceName="Open Date &amp; Time"/>
        <columnMap localName="ClosingTime" sourceName="Close Date &amp; Time"/>
        <columnMap localName="StreetAddress" sourceName="Street Address"/>
    </importMap>
</importConfiguration>
