app.config 的自定义配置 - 部分的集合? [英] Custom Configuration for app.config - collections of sections?
问题描述
我的头在剧烈地跳动!我以前做过这件事,但没有这样深入"或复杂,我尝试了不同的方法来实现这一点,但都失败了.
My head is absolutely pounding badly! I have done this before but not as "in depth" or complex as this and I have tried different ways to make this happen but all has failed.
所以,这是我在 app.config 中想要的自定义 XML:
So, this is the custom XML I want in the 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>
所以是 Profile 的集合,每个 Profile 都有一个子元素的集合(Components 是一个集合,然后 Component 是一个元素)
So a collection of Profile with each profile having a collection of sub elements (Components is a collection, then Component is an element)
但是,除了多个配置文件之外,我目前拥有所有这些.我确实看到了问题,但不确定如何修复"它.
However I currently have all that EXCEPT for the multiple profiles. I kind of do see the problem but not sure how to "fix" it.
代码:
public class Profile : ConfigurationSection
{
[ConfigurationProperty("Name", IsRequired=true)]
public string Name
{
get
{
return base["Name"] as string;
}
set
{
base["Name"] = value;
}
}
[ConfigurationProperty("Components")]
public ComponentCollection Components
{
get { return ((ComponentCollection)(base["Components"])); }
}
[ConfigurationProperty("Databases")]
public DatabaseCollection Databases
{
get
{
return ((DatabaseCollection)(base["Databases"]));
}
}
}
[ConfigurationCollection(typeof(Component), AddItemName="Component")]
public class ComponentCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new Component();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((Component)(element)).Name;
}
public Component this[int idx]
{
get
{
return base.BaseGet(idx) as Component;
}
set
{
if (base.BaseGet(idx) != null)
{
base.BaseRemoveAt(idx);
}
this.BaseAdd(idx, value);
}
}
public Component this[string key]
{
get
{
return base.BaseGet(key) as Component;
}
set
{
if (base.BaseGet(key) != null)
{
base.BaseRemove(key);
}
this.BaseAdd(this.Count, value);
}
}
}
public class Component : ConfigurationElement
{
[ConfigurationProperty("Type", IsRequired = true)]
public string Type
{
get
{
return this["Type"] as string;
}
set
{
this["Type"] = value;
}
}
[ConfigurationProperty("Name", IsRequired = true, IsKey = true)]
public string Name
{
get
{
return this["Name"] as string;
}
set
{
this["Name"] = value;
}
}
[ConfigurationProperty("ServiceName", IsRequired = false)]
public string ServiceName
{
get
{
return this["ServiceName"] as string;
}
set
{
this["ServiceName"] = value;
}
}
}
[ConfigurationCollection(typeof(Database), AddItemName = "Database")]
public class DatabaseCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new Database();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((Database)(element)).Name;
}
public Database this[int idx]
{
get
{
return base.BaseGet(idx) as Database;
}
set
{
if (base.BaseGet(idx) != null)
{
base.BaseRemoveAt(idx);
}
this.BaseAdd(idx, value);
}
}
public Database this[string key]
{
get
{
return base.BaseGet(key) as Database;
}
set
{
if (base.BaseGet(key) != null)
{
base.BaseRemove(key);;
}
this.BaseAdd(this.Count, value);
}
}
}
public class Database : ConfigurationElement
{
[ConfigurationProperty("Name", IsKey = true, IsRequired = true)]
public string Name
{
get
{
return this["Name"] as string;
}
set
{
this["Name"] = value;
}
}
[ConfigurationProperty("Connection", IsKey = false, IsRequired = true)]
public string Connection
{
get
{
return this["Connection"] as string;
}
set
{
this["Connection"] = value;
}
}
}
推荐答案
您需要将配置部分上移一级.
You need to move your configuration section one level higher.
public class Profiles : ConfigurationSection
{
[ConfigurationProperty("Profile")]
public ProfileCollection Profile
{
get
{
return this["profile"] as ProfileCollection;
}
}
}
这是我创建的一个部分.您应该能够通过以下操作让您的工作正常工作:
Here's a section that I created. You should be able to get yours working by following this:
public class ImportConfiguration : ConfigurationSection
{
[ConfigurationProperty("importMap")]
public ImportMapElementCollection ImportMap
{
get
{
return this["importMap"] as ImportMapElementCollection;
}
}
}
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;
}
}
