If all the functions get the same parameters and return the same value, you can use a Dictionary along with delegates to map a string to a function(s). This method will allow you also to change in run time the switch - allowing external programs to extend the functionality of the program.

If the functions aren't the same, you could write wrappers - a proxy function that will get parameters as all other functions, and call the functions you want.
