.NET ConfigurationManager app.config confusion

app-config, c#, configuration

Solution

Here's how I did it:

-Make sure that `System` and `System.Configuration.dll` are available in your bin directory. You do this by adding the reference to both dlls and set their `copy local` attribute to `true`.

-Make sure in your `App.Config` file, set the `copy local` attributes to `false`.

-Use the following method:

public static string XMLCheck
{
    get
    {
        var section =(Hashtable)ConfigurationManager.GetSection("PowershellSnapIns");
        return (string)section["SnapIn1"];

    }
}

-The `XMLCheck` should return "`WebAdministration`"

Problem

I've got an app.config file, which contains the following ``` <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name ="PowershellSnapIns" type ="System.Configuration.DictionarySectionHandler,System"/> </configSections> <PowershellSnapIns> <add key="SnapIn1" value="WebAdministration" /> <add key="SnapIn2" value="Jimmy Hendrix" /> <add key="SnapIn3" value="..." /> </PowershellSnapIns> </configuration> ``` I was going to use the ConfigurationSettings class to read it, but that has been deprecated. That was fairly simple to use. Now I have to use the ConfigurationManager class, and I now have this code to read it. ``` System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); IDictionary SnapInList = (IDictionary) config.GetSection("PowershellSnapIns"); ``` But it keeps erroring out. I changed the app.config properties to copy across to the build, but it keeps accepting that it can't find the file. The exception says it's looking for `TestConsole.vshost.exe.config`. Does vs2k8sp1 now rename the app.config for you automatically, and if so, what am I doing wrong? Surely I don't need to rename the app.config file to debug vhost. I do know in release that it's probably being renamed `TestConsole.exe.config`. So what's going wrong? Is it the case of the code wrong or what?
