C＃WCF System.Configuration.ConfigurationErrorsException：无法识别的元素’ManagedService’
在WCF应用程序中，我有一些自定义配置类可供app.config使用。 但是，我从WCF服务主机获取以下堆栈跟踪（它尝试在WCF服务的构造函数中检索自定义配置）：
System.Reflection.TargetInvocationException：调用目标抛出了exception。 —> System.Configuration.ConfigurationErrorsException：无法识别的元素’ManagedService’。 （Service.dll.config第8行）在System.Configuration.BaseConfigurationRecord.EvaluateOne（String []键，SectionInput输入，Boolean isTrusted，FactoryRecord factoryRecord，SectionRecord sectionRecord，Object parentResult）处于System.Configuration.BaseConfigurationRecord.Evaluate（FactoryRecord factoryRecord， SectionRecord sectionRecord，Object parentResult，Boolean getLkg，Boolean getRuntimeObject，Object＆result，Object＆resultRuntimeObject）at System.Configuration.BaseConfigurationRecord.GetSectionRecursive（String configKey，Boolean getLkg，Boolean checkPermission，Boolean getRuntimeObject，Boolean requestIsHere，Object＆result，Object＆resultRuntimeObject）at System System.Configuration.BaseConfigurationRecord.GetSectionRecursive（String configKey，Boolean getLkg，Boolean chec）.Configuration.BaseConfigurationRecord.GetSectionRecursive（String configKey，Boolean getLkg，Boolean checkPermission，Boolean getRuntimeObject，Boolean requestIsHere，Object＆result，Object＆resultRuntimeObject） 位于ManagementService.cs中ManagementService..ctor（）的System.Configuration.ConfigurationManager.GetSection（String sectionName）的System.Configuration.BaseConfigurationRecord.GetSection（String configKey）中的kPermission，Boolean getRuntimeObject，Boolean requestIsHere，Object＆result，Object＆resultRuntimeObject）：第42行—内部exception堆栈跟踪的结束—在System.Reflection.RuntimeConstructorInfo.Invoke的System.RuntimeMethodHandle._InvokeConstructor（IRuntimeMethodInfo方法，Object [] args，SignatureStruct＆signature，RuntimeType declaringType）中（BindingFlags invokeAttr，Binder binder， Object []参数，CultureInfo文化）

（抱歉讨厌的堆栈跟踪）。
我在这里看了很多关于这个错误的教程和其他问题，并没有提出任何建议或解决方案。
这是app.config的相关部分
基本上，此WCF服务用于管理在启动时动态加载和启动的其他服务（通过此配置通知）。
来自ManagedServicesSection ，它inheritance自ConfigurationSection
public class ManagedServicesSection : ConfigurationSection { [ConfigurationProperty("services", IsDefaultCollection = true)] public ManagedServiceCollection ServiceCollection { get { return (ManagedServiceCollection) base["services"]; } } }
从中可以看出， 是一个MangedServiceCollection ，它inheritance自ConfigurationElementCollection
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; } }
此集合包含inheritance自ConfigurationElement ManagedService ：
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"]; } } }

我无法完成您的示例，ServiceParameterCollection丢失了…所以我已经为您准备了我的工作样本。 开始了…
首先让我们创建配置类，注意AddItemName ConfigurationCollection参数（我认为这是你在代码中缺少的）：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Configuration; namespace GP.Solutions.WF.DocumentProvider.Entities.SharePoint { /// /// Base SharePoint 2010 provider contiguration /// [Serializable] public class SharePoint2010Settings : ConfigurationSection { /// /// DocumentStorageRoot /// [ConfigurationProperty("SiteUrl", IsRequired = true, DefaultValue = "")] public string SiteUrl { get { return (string)base["SiteUrl"]; } set { base["SiteUrl"] = value; } } /// /// TitleProperty /// [ConfigurationProperty("TitleProperty", IsRequired = true, DefaultValue = "Title")] public string TitleProperty { get { return (string)base["TitleProperty"]; } set { base["TitleProperty"] = value; } } /// /// ProvideFileAsLink /// [ConfigurationProperty("ProvideFileAsLink", IsRequired = true, DefaultValue = true)] public bool ProvideFileAsLink { get { return (bool)base["ProvideFileAsLink"]; } set { base["ProvideFileAsLink"] = value; } } /// /// DocumentCategories /// [ConfigurationProperty("DocumentCategories")] public SharePointDocumentCategoryCollection DocumentCategories { get { return (SharePointDocumentCategoryCollection)base["DocumentCategories"]; } set { base["DocumentCategories"] = value; } } } /// /// Configuration element that holds SharePointDocumentCategory collection /// [ConfigurationCollection(typeof(SharePointDocumentCategory), AddItemName = "DocumentCategory", CollectionType = ConfigurationElementCollectionType.BasicMap)] public class SharePointDocumentCategoryCollection : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { return new SharePointDocumentCategory(); } protected override object GetElementKey(ConfigurationElement element) { return ((SharePointDocumentCategory)element).CategoryName; } } /// /// Configuration element that holds information for specific document category /// [Serializable] public class SharePointDocumentCategory: ConfigurationElement { /// /// CategoryName /// [ConfigurationProperty("CategoryName", IsRequired = true, DefaultValue = "")] public string CategoryName { get { return (string)base["CategoryName"]; } set { base["CategoryName"] = value; } } /// /// FolderName /// [ConfigurationProperty("FolderName", IsRequired = true, DefaultValue = "")] public string FolderName { get { return (string)base["FolderName"]; } set { base["FolderName"] = value; } } /// /// TitleProperty /// [ConfigurationProperty("OverwriteFiles", IsRequired = true, DefaultValue = true)] public bool OverwriteFiles { get { return (bool)base["OverwriteFiles"]; } set { base["OverwriteFiles"] = value; } } /// /// DocumentCategories /// [ConfigurationProperty("CategoryFields")] public SharePointCategoryFieldsCollection CategoryFields { get { return (SharePointCategoryFieldsCollection)base["CategoryFields"]; } set { base["CategoryFields"] = value; } } } /// /// Configuration element that holds SharePointDocumentCategory collection /// [ConfigurationCollection(typeof(SharePointDocumentCategory), AddItemName = "CategoryField", CollectionType = ConfigurationElementCollectionType.BasicMap)] public class SharePointCategoryFieldsCollection : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { return new SharePointCategoryField(); } protected override object GetElementKey(ConfigurationElement element) { return ((SharePointCategoryField)element).FieldName; } } /// /// Class that determines specific field /// [Serializable] public class SharePointCategoryField : ConfigurationElement { /// /// FolderName /// [ConfigurationProperty("FieldName", IsRequired = true, DefaultValue = "")] public string FieldName { get { return (string)base["FieldName"]; } set { base["FieldName"] = value; } } } }
