How to generate help text at runtime for logging purposes

I'm trying to find a way to generate the help text (that would be displayed if the user asked for it) at runtime when there is a parsing error. We want to log this help text for console apps that run unattended during the night and where for some reason incorrect args were setup for the job.

I can see stuff like CommandLine.Texy.HelpText.RenderUsage and so on but I have no idea what these do and they don't seem to do what we need.

Many thnaks.

檢視提到的 CommandLine.Texy.HelpText.RenderUsage API 和解析錯誤路徑，以確定目前如何產生說明文字。重現無人值守主控台應用程式情境，並將記錄在要求時會顯示的相同說明文字定義為完成條件。未指定檔案或測試，因此需要探索 repository 並釐清範圍。
