Today I found this piece of code in an integration to RemoteX Application.

switch (ConfigurationManager.AppSettings["UsePriority"]) {  
    case "false":
        switch (... ) {
            case true:
                log.Write
                ...
                break;
            case false:
                log.Write
                ...
                break;
            };
        break;
   case "true":
           switch (... ) {
            case true:
                log.Write
                ...
                break;
            case false:
                log.Write
                ...
                break;
        };
           break;
}

The dotted out code was application logic, so I omited it.
