C＃自定义配置元素

Question

我正在开发一种需要位于App / config（Web.config）文件中的高级配置的工具。为实现这一点，我使用了自定义配置部分

App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="webConfiguration" type="MyConfigurationType, MyAssembly" />
  </configSections>

  <webConfiguration>
     <requests>
        <request name="Request-One">
            <!-- details here, but they don't matter -->
        </request>
        <request name="Request-Two" basedOn="Request-One">
            <!-- details here, but they don't matter -->
        </request>
     </requests>
  </webConfiguration>
</configuration>

RequestElement.cs

public class RequestElement : ConfigurationElement
{
    [ConfigurationProperty("name", IsKey = true, IsRequired = true)]
    public string Name
    {
        get { return (string)base["name"]; }
        set { base["name"] = value; }
    }

    [ConfigurationProperty("basedOn", IsRequired = false)]
    public string BasedOn
    {
        get
        {
            return (string)this["basedOn"];
        }
        set
        {
            this["basedOn"] = value;
        }
    }
}

如您所见，这很简单。它正在编译和工作，没有例外。我要问的是，是否可以创建RequestElement类型的配置属性并将其链接到正确的？（如下所示）

RequestElement.cs

public class RequestElement : ConfigurationElement
{
    [ConfigurationProperty("name", IsKey = true, IsRequired = true)]
    public string Name
    {
        get { return (string)base["name"]; }
        set { base["name"] = value; }
    }

    [ConfigurationProperty("basedOn", IsRequired = false)]
    public RequestElement BasedOn
    {
        get
        {
            return (RequestElement)this["basedOn"];
        }
        set
        {
            this["basedOn"] = value;
        }
    }
}

正如您所注意到的，Name是一个密钥，因此在App.config文件中使用名称会导致在打开ConfigurationManager并获得正确的部分后，请求和任何请求，将能够使用BasedOn属性访问真实对象。
