// créer une classe dont l'instance sera passée à la méthode ParseArguments
class Options
{
[Usage(ApplicationAlias = "My Application")]
public static IEnumerable<Example> Examples => new List<Example>()
{

"Description of the application",
new Options { Option1 = "Option1", Option2 = 100 })
};

Parsing
|
|
static int Main(string[] args)
{
return Parser.Default.ParseArguments<Options>(args)
.MapResult(
options => RunAndReturnExitCode(options),
_ => 1);
|
Parsing with async
|
|
public static async Task Main(string[] args)
{
var result = Parser.Default.ParseArguments<Options>(args)
.MapResult(
async options => await RunAndReturnExitCodeAsync(options),
_ => Task.FromResult(1));
|
Command line
 |
In case of missing or unknown argument or parsing error, the errors are displayed with the usage explanation message and the application exits. |
|
By default options --help and --version are available. |
|
# option1 -o value -ovalue --option1 value --option1=value |
