CliArgumentAttributeArity Property

Gets or sets the arity of the argument. The arity refers to the number of values that can be passed on the command line.

In most cases setting argument arity is not necessary as it is automatically determined based on the argument type (the decorated property's type):

• Boolean -> ArgumentArity.ZeroOrOne
• Collection types -> ArgumentArity.ZeroOrMore
• Everything else -> ArgumentArity.ExactlyOne
