如何使用DictionarySectionHandler在Web.Config中检索Key的值

Question

How to fetch the corresponding value of a key that I would get dynamically. I wish to use the system defined DictionarySectionHandler to do the job, of fetching the data from my custom built config section in the Web.config file

Code block in Web.Config

<section name="domainsource" type="System.Configuration.DictionarySectionHandler"/>

  <domainSource>
         <add key="0" value="170" />
         <add key="1" value="171" />
         <add key="2" value="172" />
         <add key="3" value="173" />
         <add key="12" value="174" />
  </domainSource>

Sourcecode in the main cs file from where I wish to retrieve the data from the Web.Config

Hashtable statusCodes = ConfigurationManager.GetSection("domainSource") as Hashtable;
vDomainSource = statusCodes[vDomainID];

This is where I am stuck vDomainID would be a value 0/1/2/3/12, based on this value I need to fetch its respective Source from the Web.Config. Any help on this aspect would be really appreciated.

You have a missspelling in the defintion of the section domainsource -> domainSource. Further ensure that the elemnt is defined in an element. Then it should work.

<configuration>
  <configSections>
  <section name="domainSource" type="System.Configuration.DictionarySectionHandler"/>
    </configSections>
  <domainSource>
    <add key="0" value="170" />
    <add key="1" value="171" />
    <add key="2" value="172" />
    <add key="3" value="173" />
    <add key="12" value="174" />
  </domainSource>
</configuration>
