app.config的自定义配置 - 部分的集合?

问题描述:

我的头绝对糟糕!我之前做过这些,但没有像这样“深入”或复杂,我尝试了不同的方法来实现这一点,但都失败了。app.config的自定义配置 - 部分的集合?

所以,这是自定义XML我想在App.config:

<Profiles> <!--Collection--> 
<Profile Name="Live"> 
    <Components> 
    <Component Name="Portal" Type="Web" /> 
    <Component Name="Comms" Type="Web" /> 
    <Component Name="Scheduler" Type="WindowsService" ServiceName="LiveScheduler" /> 
    </Components> 
    <Databases> 
    <Database Name="Main" Connection="Data Source=.\SQL2008" /> 
    <Database Name="Staging" Connection="Data Source=SomeSite.co.uk" /> 
    </Databases> 
</Profile> 
<Profile Name="Test"> 
    <Components> 
    <Component Name="Portal" Type="Web" /> 
    <Component Name="Comms" Type="Web" /> 
    <Component Name="Scheduler" Type="WindowsService" ServiceName="TestScheduler" /> 
    </Components> 
    <Databases> 
    <Database Name="Main" Connection="Data Source=.\SQL2008" /> 
    <Database Name="Staging" Connection="Data Source=Internal" /> 
    </Databases> 
</Profile> 
</Profiles> 

因此,与每个配置文件有子元素的集合(组件是一个集合档案的收集,那么组件是元素)

但是我目前除了多个配置文件外都有其他所有的功能。我有点看到问题,但不知道如何“修复”它。

代码:

public class Profile : ConfigurationSection 
{ 
    [ConfigurationProperty("Name", IsRequired=true)] 
    public string Name 
    { 
     get

似乎你想有不同的环境,你为什么不看慢猎豹扩展VS这是本周公布的不同的配置文件。几乎没有你想要的:http://www.sadev.co.za/content/appconfig-transformations-community-shines-where-microsoft-drops-ball –

关于代码问题的任何信息? – Jodrell

你正确地执行,除非你需要一个额外的水平。将配置文件从ConfigurationSection更改为ConfigurationElement,然后制作包含配置文件项目集合的ConfigurationSection配置文件。

这是一个很好的自动测试案例,调试配置部分没有是一个皇室的痛苦。

谢谢你的回复到目前为止。 Cheetah扩展看起来很有趣。 –

woops ..按下输入得太快。 ssamuel - 我相信我之前尝试过你的方法,但没有除了抛出异常的地方说它需要实现IConfigurationSectionHandler。我会看看我能否再次做到这一点。但是我不知道它是否更快地将一个对象序列化或反序列化为XML并且使用它是诚实的: -/ –

呃,你使用哪个版本的FW? IConfigurationSectionHandler在2.0之后被弃用。如果你仍然在寻找,[试试这个](http://msdn.microsoft.com/en-us/library/2tw134k3.aspx)。序列化到XML更快,更直观。写入配置更漂亮。取决于您想要在系统管理员或开发人员身上留下维护难度的位置。 – ssamuel

您需要将配置部分移动一级。

public class Profiles : ConfigurationSection 
{ 
    [ConfigurationProperty("Profile")] 
    public ProfileCollection Profile 
    { 
     get 
     { 
      return this["profile"] as ProfileCollection; 
     } 
    } 
}  

这是我创建的部分。你应该能够得到你的工作由以下这一点:

public class ImportConfiguration : ConfigurationSection 
{ 
    [ConfigurationProperty("importMap")] 
    public ImportMapElementCollection ImportMap 
    { 
     get

    }

public class ImportColumnMapElement : ConfigurationElement 
{ 
    [ConfigurationProperty("localName", IsRequired = true, IsKey = true)] 
    public string LocalName 
    { 
     get 
     { 
      return this["localName"] as string; 
     } 
     set 
     { 
      this["localName"] = value; 
     } 
    } 

    [ConfigurationProperty("sourceName", IsRequired = true)] 
    public string SourceName 
    { 
     get 
     { 
      return this["sourceName"] as string; 
     } 
     set 
     { 
      this["sourceName"] = value; 
     } 
    } 
} 

public class ImportMapElementCollection : ConfigurationElementCollection 
{ 
    public ImportColumnMapElement this[object key] 
    { 
     get 
     { 
      return base.BaseGet(key) as ImportColumnMapElement; 
     } 
    } 

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

    protected override string ElementName 
    { 
     get 
     { 
      return "columnMap"; 
     } 
    } 

    protected override bool IsElementName(string elementName) 
    { 
     bool isName = false; 
     if (!String.IsNullOrEmpty(elementName)) 
      isName = elementName.Equals("columnMap"); 
     return isName; 
    } 

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

    protected override object GetElementKey(ConfigurationElement element) 
    { 
     return ((ImportColumnMapElement)element).LocalName; 
    } 
}
