Question

I have saved strings in a dll application’s setting. I want to retireve them.

Here is the configuration file for my dll:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxxxxxxxx" >
            <section name="Search.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <applicationSettings>
        <PishiSearch.Properties.Settings>
            <setting name="ReadIndex" serializeAs="String">
                <value>C:\Index</value>
            </setting>
            <setting name="WriteIndex" serializeAs="String">
                <value>C:\WriteIndex</value>
            </setting>
        </PishiSearch.Properties.Settings>
    </applicationSettings>
</configuration>

It resides in the same directory as my dll. It is called: Search.dll.config
My dll is called: Search.dll

I want to read the values of ReadIndex and WriteIndex from this config file into my dll.

Here is the code:

    var executingAssembly = System.Reflection.Assembly.GetExecutingAssembly();
    var location = executingAssembly.Location; //C:\MyApp\bin\Debug\Search.dll
    var config = ConfigurationManager.OpenExeConfiguration(location);
    var sections = config.Sections; //count of this is 21
    ConfigurationSectionGroup csg = config.GetSectionGroup("applicationSettings");
    ConfigurationSectionCollection csc = csg.Sections;
    ConfigurationSection cs = csc.Get("Search.Properties.Settings");

The code works up to getting the last line here. But how do I get the settings strings?

Yes I can use cs.SectionInformation.GetRawXml(); to get the xml and then interrogate it to get the values, but that is a kluge.
How do I read the values? Preferably into a Settings object? Many thanks!

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <applicationSettings>

    </applicationSettings>
    <appSettings>
        <add key="ReadIndex" value="C:\Index"/>
    </appSettings>
</configuration>


var executingAssembly = System.Reflection.Assembly.GetExecutingAssembly();
var location = executingAssembly.Location; //C:\MyApp\bin\Debug\Search.dll
var config = ConfigurationManager.OpenExeConfiguration(location);
var sections = config.Sections; //count of this is 21
string s = config.AppSettings.Settings["ReadIndex"].Value.ToString();
