Adding a simple custom section in App.config c#

In App.config: you need to set up a configSections / sectionGroup sections, then you can add your custom sections below appSettings:

xml version="1.0"?>

<configuration>

  <configSections>

    <sectionGroup name="EpicSettings">

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

    </sectionGroup>

  </configSections>

  <startup>

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

  </startup>

  <appSettings>

    <add key="rootLevel" value="C:\Program Files (x86)\Epic"/>

    

    <add key="drFltr" value="Interconnect-*"/>

    <add key="DevVersion" value="Interconnect-DEV"/>

    <add key="CmdBldr" value="CommandBuilder.exe"/>

    <add key="CnfgEdt" value="ConfigEditor.exe"/>

    <add key="TrcVw" value="TraceViewer.exe"/>

    <add key="GnrlCnfg" value="\Web\App_Data\Config\General.config"/>

    <add key="WbSvPxyBldrSubDir" value="\Tools\"/>

    <add key="WbSvPxyBldr" value="WebServiceProxyBuilder.exe"/>

    <add key="PhsGenSvcSubDir" value="\Web\bin\"/>

  </appSettings>

  

  <EpicSettings>

    <EpicVersions>

      <add key="v7.9" value="Epic 2012"/>

      <add key="v8.1" value="Epic 2014"/>

    </EpicVersions>

  </EpicSettings>

</configuration>

In code:  Here is one way to access your custom section in the code:  Here we’re trying to determine the Epic Version based on if the directory path contains a string matching one of the config keys.

private string getEpicVersion(string vrsnpth)

        {

            string ret = string.Empty;

            var epicVersions = (ConfigurationManager.GetSection("EpicSettings/EpicVersions") as System.Collections.Hashtable)

                 .Cast()

                 .ToDictionary(n => n.Key.ToString(), n => n.Value.ToString());

            foreach (System.Collections.Generic.KeyValuePair<string, string> vrsn in epicVersions)

            {

                if (vrsnpth.ToLower().Contains(vrsn.Key.ToLower()))

                {

                    ret = vrsn.Value;

                    break;

                }

            }

            return ret;

        }
