自定义C＃config无法识别的元素exception

我在App.config中有以下针对.NET 3.5 Windows服务的位：

我在configurationServiceSection.config中有这个：

这是代码：

 using System.Configuration; namespace SomeApp.Framework.Configuration { public sealed class ConfigurationServiceSection : ConfigurationSection { [ConfigurationProperty("ConfigurationServices", IsDefaultCollection = true, IsRequired = true)] [ConfigurationCollection(typeof(ConfigurationServices))] public ConfigurationServices ConfigurationServices { get { return (ConfigurationServices)base["ConfigurationServices"]; } } } public sealed class ConfigurationServices : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { return new ConfigurationService(); } protected override object GetElementKey(ConfigurationElement element) { ConfigurationService configService = (ConfigurationService) element; return configService.Name; } } public sealed class ConfigurationService : ConfigurationElement { /// 
 /// name /// 
 [ConfigurationProperty("name", IsKey = true, IsRequired = true)] public string Name { get { return (string)this["name"]; } set { this["name"] = value; } } /// 
 /// host /// 
 [ConfigurationProperty("host", IsKey = false, IsRequired = true)] public string Host { get { return (string)this["host"]; } set { this["host"] = value; } } /// 
 /// port /// 
 [ConfigurationProperty("port", IsKey = false, IsRequired = true)] public string Port { get { return (string)this["port"]; } set { this["port"] = value; } } /// 
 /// location /// 
 [ConfigurationProperty("location", IsKey = false, IsRequired = true)] public string Location { get { return (string)this["location"]; } set { this["location"] = value; } } } } 

当我尝试使用以下内容访问配置时：

 var configurationServiceSection = (ConfigurationServiceSection)configuration.GetSection("ConfigurationServiceSection"); 

我得到这个例外：

 Unrecognized element 'ConfigurationService'. (C:\Code\branches\ConfigurationService\SomeApp\Src\ConfigService\SomeApp.ConfigService.WindowsService\bin\Debug\ConfigSections\configurationServiceSection.config line 3) 

一切都看起来对我来说？

有什么想法吗？ 谢谢。

好了到底：

我将’AddItemName’添加到ConfigurationServiceSection类，如下所示：

 public sealed class ConfigurationServiceSection : ConfigurationSection { [ConfigurationProperty("ConfigurationServices", IsDefaultCollection = true, IsRequired = true)] [ConfigurationCollection(typeof(ConfigurationServices), AddItemName = "ConfigurationService")] public ConfigurationServices ConfigurationServices { get { return (ConfigurationServices)base["ConfigurationServices"]; } } } 

另一种方法是覆盖CollectionType和ElementName属性，如下所示：

 public override ConfigurationElementCollectionType CollectionType { get { return ConfigurationElementCollectionType.BasicMap; } } protected override string ElementName { get { return "ConfigurationService"; } }
