Provides the Arguments class that gives you access to command-line interface arguments:

Constructor

public Arguments(params string[] commandLine)

The commandLine is parsed as arguments starting with -, -- or / followed by the argument name then either = or : and then the argument value.

The following are valid arguments:

-name=value
--name=value
/name=value
-name:value
--name:value
/name:value

The argument name and value may be quoted with either a single quote (') or double quote (").

An Arguments instance may be constructed from the Environment.GetCommandLineArgs() values using the Arguments.FromCommandLine() static factory method.

Checking for values

public bool Contains(string name)

Returns true if the given argument name is found; else false.

Getting values

public T Get<T>(string name)
public T Get<T>(string name, T @default)

Returns the value of the given argument name as type T. If the argument name cannot be found the value given as @default will be returned. If not @default is specified an InvalidOperationException is thrown.

Argument definitions

You can add ArgumentDefinition entries to an Arguments instance by using the following method:

public Arguments Add(ArgumentDefinition definition)

Argument definitions must have unique keys and if aliases are used these too have to be unique across definitions. Duplicate aliases within the same argument definition will be ignored.

An argument definition may be marked as required by calling the AsRequired() method which will set the IsRequired property to true. You can then call the HasMissingValues() method on the Arguments class which will return true is there are any required arguments that have not been specified using either the proper name or an alias.
