[英]How to retrieve the value for the Key in the Web.Config using DictionarySectionHandler
[英]How to retrieve the value for the Key in the Web.Config via C#
我正在通過VS2012構建Web服務,並且需要根據從存儲過程中獲取的動態數據從Web.Config文件中獲取一些數據。
Web.Config中的代碼塊
<domainSource>
<domainIDs>
<add name="0" source="170" />
<add name="1" source="171" />
<add name="2" source="172" />
<add name="3" source="173" />
<add name="12" source="174" />
</domainIDs>
</domainSource>
DomainConfiguration.cs中的源代碼如下
public class DomainElement : ConfigurationElement
{
[ConfigurationProperty("name", IsKey = true, IsRequired = true)]
public string Name
{
get { return (string)this["name"]; }
set { this["name"] = value; }
}
[ConfigurationProperty("source", IsRequired = true, DefaultValue = "170")]
public string Source
{
get { return (string)this["source"]; }
set { this["source"] = value; }
}
}
[ConfigurationCollection(typeof(DomainElement))]
public class DomainCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new DomainElement();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((DomainElement)element).Name;
}
}
public class DomainSection : ConfigurationSection
{
[ConfigurationProperty("domainIDs", IsDefaultCollection = true)]
public DomainCollection DomainID
{
get { return (DomainCollection)this["domainIDs"]; }
set { this["domainIDs"] = value; }
}
}
我要從中從Web.Config檢索數據的主要CS文件中的源代碼
vDomainID = new B2B().Domain(SourceID, Subject);
DomainCollection collection;
collection = ConfigurationManager.GetSection("domainSource") as DomainCollection;
vDomainSource = collection[vDomainID];
在這里我被卡住了vDomainID將是一個值0/1/2/3/12,基於該值,我需要從Web.Config中獲取其各自的Source。 在這方面的任何幫助將不勝感激。
你很親密 您想將ConfigurationManager.GetSection("domainSource")
DomainSection
為DomainSection
(Not DomainCollection) 。
public class DomainElement : ConfigurationElement
{
[ConfigurationProperty("name", IsKey = true, IsRequired = true)]
public string Name
{
get { return (string)this["name"]; }
set { this["name"] = value; }
}
[ConfigurationProperty("source", IsRequired = true, DefaultValue = "170")]
public string Source
{
get { return (string)this["source"]; }
set { this["source"] = value; }
}
}
[ConfigurationCollection(typeof(DomainElement))]
public class DomainCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new DomainElement();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((DomainElement)element).Name;
}
}
public class DomainSection : ConfigurationSection
{
[ConfigurationProperty("domainIDs", IsDefaultCollection = true)]
public virtual DomainCollection domainIDs
{
get { return (DomainCollection)this["domainIDs"]; }
}
}
string vDomainID = "0";
var domainSource = ConfigurationManager.GetSection("domainSource") as DomainSection;
var domainIDs = domainSource.domainIDs;
foreach (DomainElement item in domainIDs)
{
if (item.Name.Equals(vDomainID))
{
// Do something.
}
}
