cli in c# How to catch an error of a required option

Question

    var languageOption = new Option<string>("--language", "file path and name") { IsRequired = true };

אז איך אני עושה שאם המשתמש לא מקיש את השפה זה לא יזרוק לן הודעת שגיאה ברירת מחדל אלא הודעת שגיאה שאני אחליט

Hi @מממם ,

If you set the option IsRequired = true, the default error "Option '--language' is required" is always triggered first.

If you want to display your own error message, you can instead set it to required, but manually determine whether it is empty in your code and output the error message.

Best Regards.
