I keep getting a null reference when trying to access my config file
through my windows service, I have placed the xml config file in my
debug folder with my .exe, and my code is shown below.

//where I call the app.config file
f =
X10Unified.Senders.Firecracker.GetInstance(Int32.Parse(System.Configuration.ConfigurationManager.AppSettings["COM_Port"]));

//the config file
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="applicationSettings"
type="System.Configuration.ApplicationSettingsGroup, System,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="namespace.Properties.Settings"
type="System.Configuration.ClientSettingsSection, System,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
requirePermission="false" />
</sectionGroup>
</configSections>
<applicationSettings>
<namespace.Properties.Settings>
<setting name="namespace_Service_gLink"
serializeAs="String">
<value>url</value>
</setting>
<setting name="COM_Port" serializeAs="String">
<value>"3"</value>
</setting>
</namespace.Properties.Settings>
</applicationSettings>
</configuration>
 
Cody,
ConfigurationManager.AppSettings is only for reading the standard
appSettings standalone section that looks like this:

<appSettings>
<add key="yourKey" value="yourValue" />
</appSettings>

You need to use one of the configurationSettings reader classes to read your
custom "applicationSettings" Section.

Peter,
I seem to be having some difficulties with this, what is the simplest
way to use a config file with a windows service? All i need it to do
is be able to contain an int or a string.

1) Add an "Application Configurate File" to your project. It will be named
"app.config" during development. After a build, it will automatically be
copied to the runtime folder with the name "yourappname.exe.config".
2) use an appSettings section as detailed in my first response above, and
access the items with ConfigurationManager.AppSettting["keyname"];
That's it, aside from remembering to convert string values to integers.
