HOWTO: Programatically Configure Error Pages Features Settings in IIS 7.0

I would like to programmatically (C#) configure IIS 7.0 for a given application, to do the equivalent of manually:

Computer Management => Services and Applications => Internet Information Services => Sites => Default Web Site => ApplicationName => Error Pages
Clicking "Edit Feature Setttings..."
Under "Error Reponses" set "When the server encounter an error, return:" to "Custom error pages".

Thanks,
Michael

Thanks sedgwick!

I tried to adapt the sample code you have posted to configure a single application (as I requested in my question above), but I get the following exception:

System.Reflection.TargetInvocationException: Exception has been thrown by the ta
rget of an invocation. ---> System.IO.FileLoadException: This configuration sect
ion cannot be used at this path. This happens when the section is locked at a pa
rent level. Locking is either by default (overrideModeDefault="Deny"), or set ex
plicitly by a location tag with overrideMode="Deny" or the legacy allowOverride=
"false".

See source code below.

Thanks,
Michael

using (ServerManager serverManager = new ServerManager()) {
    Microsoft.Web.Administration.Configuration config = serverManager.GetWebConfiguration("Default Web Site", "/MediaServerWeb");
    Microsoft.Web.Administration.ConfigurationSection httpErrorsSection = config.GetSection("system.webServer/httpErrors");
    httpErrorsSection.Attributes["errorMode"].Value = 1; // "Custom";
    serverManager.CommitChanges();
}
