示例1: MapExeConfiguration

' Access a configuration file using mapping.
' This function uses the OpenMappedExeConfiguration 
' method to access a new configuration file.   
' It also gets the custom ConsoleSection and 
' sets its ConsoleElement BackgroundColor and
' ForegroundColor properties to green and red
' respectively. Then it uses these properties to
' set the console colors.
