我在 .NET 3.5 的 Windows Service 的 App.config 中有以下的配置:
<configSections>
<section name="ConfigurationServiceSection" type="SomeApp.Framework.Configuration.ConfigurationServiceSection, SomeApp.Framework"/>
</configSections>
<ConfigurationServiceSection configSource="ConfigSections\configurationServiceSection.config" />
我在configurationServiceSection.config文件中找到了以下内容:
<ConfigurationServiceSection>
<ConfigurationServices>
<ConfigurationService name="LocalConfig" host="localhost" port="40001" location="LON"/>
</ConfigurationServices>
</ConfigurationServiceSection>
以下是代码:
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
{
/// <summary>
/// name
/// </summary>
[ConfigurationProperty("name", IsKey = true, IsRequired = true)]
public string Name
{
get { return (string)this["name"]; }
set { this["name"] = value; }
}
/// <summary>
/// host
/// </summary>
[ConfigurationProperty("host", IsKey = false, IsRequired = true)]
public string Host
{
get { return (string)this["host"]; }
set { this["host"] = value; }
}
/// <summary>
/// port
/// </summary>
[ConfigurationProperty("port", IsKey = false, IsRequired = true)]
public string Port
{
get { return (string)this["port"]; }
set { this["port"] = value; }
}
/// <summary>
/// location
/// </summary>
[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文件时:
var configurationServiceSection = (ConfigurationServiceSection)configuration.GetSection("ConfigurationServiceSection");
我收到了这个异常:
Unrecognized element 'ConfigurationService'. (C:\Code\branches\ConfigurationService\SomeApp\Src\ConfigService\SomeApp.ConfigService.WindowsService\bin\Debug\ConfigSections\configurationServiceSection.config line 3)
我觉得一切看起来都没问题了?
有什么想法吗?谢谢。
