visual studio 2008 - Command line parser NDesk.Options - How to Indicate mandatory parameters -


i have console application made in .net framework 3.5 , visual studio 2008.

this app can mandatory parameters , options, example:

myapp.exe -v -f foldername hostname user pwd

  • -v , -f options
  • hostname, user , pwd mandatory parameters

i have checked ndesk.options recognize mandatory parameters unknown parameters since not registered options , place in list of string once parse function called.

so how can i:

  1. indicate ndesk.options these parameters (hostname, user , pwd) mandatory , need entered?
  2. indicate maximum of paramters permitted 3.
