Localize a value of attribute

[KaiHuaDou]

    [Option('i', "input", Required = true, HelpText = "My Help Text")]
    public string Input { get; set; }

Is there any solution to localize the string "My Help Text"?

The common practice is to encode a key in attribute/code, then implement lookup from localized resource when displaying.
Is this related to System.CommandLine?

I use CommandLineParser, So it means I should set the value of the attributte in runtime with reflection?

Attribute data can't be set via reflection. You can manually create the data structure parsed from attribute, or create a feature request about localization.
