WCF アプリケーションには、.NET で使用するカスタム構成クラスがいくつかありますapp.config。ただし、WCF サービス ホストから次のスタック トレースを取得しています (WCF サービスのコンストラクターでカスタム構成を取得しようとします)。

System.Reflection.TargetInvocationException: 呼び出しのターゲットによって例外がスローされました。---> System.Configuration.ConfigurationErrorsException: 要素 'ManagedService' を認識できません。(Service.dll.config 行 8) System.Configuration.BaseConfigurationRecord.EvaluateOne(String[] キー、SectionInput 入力、Boolean isTrusted、FactoryRecord factoryRecord、SectionRecord sectionRecord、Object parentResult) で System.Configuration.BaseConfigurationRecord.Evaluate(FactoryRecord factoryRecord、 System.Configuration.BaseConfigurationRecord.GetSectionRecursive(String configKey, Boolean getLkg, Boolean checkPermission, Boolean getRuntimeObject,
System.ServiceModel.Description.ServiceDescription.CreateImplementation (型 serviceType) で System.ServiceModel.Description.ServiceDescription.GetService (型 serviceType) でSystem.ServiceModel.ServiceHost..ctor の (UriSchemeKeyedCollection baseAddresses) (型 serviceType、Uri[] baseAddresses) Microsoft.Tools.SvcHost.ServiceHostHelper.CreateServiceHost (型の種類、ServiceKind 種類) の Microsoft.Tools.SvcHost.ServiceHostHelper.OpenService ( ServiceInfo 情報) System.Configuration.ConfigurationErrorsException: 要素 'ManagedService' を認識できません。(Service.dll.config 行 8) System.Configuration.BaseConfigurationRecord で。

（厄介なスタックトレースで申し訳ありません）。

このエラーに関する多くのチュートリアルやその他の質問をここで見ましたが、提案や解決策はどこにも行きませんでした.

の関連部分は次のとおりです。app.config

<configSections>
     <section name="ManagedServices" type="Service.Configuration.ManagedServicesSection, Service, Version=1.0.0.0, Culture=neutral " allowLocation="true" allowDefinition="Everywhere" restartOnExternalChanges="false" />
</configSections>
  <ManagedServices>
     <services>
        <ManagedService serviceAssembly="Service" serviceType="Service.Runnables.HostManagerRunner" identifier="HostManager" priority="0">
           <clear />
        </ManagedService>
        <ManagedService serviceAssembly="Service" serviceType="Service.Runnables.TimeoutMonitor" identifier="TimeoutMonitor" priority="0">
           <add key="timeoutLength" value="30" />
           <add key="runInterval" value="30" />
        </ManagedService>
     </services>
  </ManagedServices>

基本的に、この WCF サービスは、起動時に動的に読み込まれて開始される (この構成を介して通知される) 他のサービスを管理するために使用されます。

<ManagedServices>からManagedServicesSection継承されるConfigurationSection

public class ManagedServicesSection : ConfigurationSection
{

  [ConfigurationProperty("services", IsDefaultCollection = true)]
  public ManagedServiceCollection ServiceCollection
  {
     get { return (ManagedServiceCollection) base["services"]; }
  }

}

これからわか​​るように、<services>はMangedServiceCollectionConfigurationElementCollection

public class ManagedServiceCollection : ConfigurationElementCollection
{

  public ManagedServiceCollection()
  {
  }

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

  public ManagedService this[int index]
  {
     get { return BaseGet(index) as ManagedService; }
     set
     {
        if (BaseGet(index) != null)
           BaseRemoveAt(index);

        BaseAdd(index, value);
     }
  }

  public ManagedService this[string name]
  {
     get { return BaseGet(name) as ManagedService; }
     set 
     { 
        if (BaseGet(name) != null)
           BaseRemove(name);

        BaseAdd(value);
     }
  }

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

  protected override object GetElementKey(ConfigurationElement element)
  {
     return ((ManagedService)element).Identifier;
  }
}

このコレクションはManagedServiceから継承する を保持しますConfigurationElement:

public class ManagedService : ConfigurationElement
{
  [ConfigurationProperty("serviceAssembly", IsRequired = true)]
  public string ServiceAssembly
  {
     get { return (string) this["serviceAssembly"]; }
     set { this["serviceAssembly"] = value; }
  }

  [ConfigurationProperty("serviceType", DefaultValue = "IRunnable", IsRequired = true)]
  public string ServiceType 
  { 
     get { return (string) this["serviceType"]; }
     set { this["serviceType"] = value; }
  }

  [ConfigurationProperty("identifier", IsRequired = true, IsKey = true)]
  public string Identifier
  {
     get { return (string) this["identifier"]; }
     set { this["identifier"] = value; }
  }


  [ConfigurationProperty("priority", DefaultValue = 0, IsRequired = false)]
  public int Priority
  {
     get { return (int) this["priority"]; }
     set { this["priority"] = value; }
  }

  [ConfigurationProperty("serviceParameters", IsDefaultCollection = true)]
  public ServiceParameterCollection ServiceParameters
  {
     get { return (ServiceParameterCollection)base["serviceParamters"]; }
  }
}

コードはこのペーストで見やすいかもしれません。pastie.org/private/jkiylqsrklpcdbtfdrajq

サンプルに準拠できませんでした。ServiceParameterCollection がありませんでした...そのため、作業サンプルを準備しました。どうぞ...

まず、構成クラスを作成し、AddItemName ConfigurationCollection パラメーターに注意してください (これは、コードに欠けているものだと思います)。
