Is it possible to use two record helpers for the string type?
问题 I created this helper in order to add some more functions to the string type: type AStringHelper = record helper for string function Invert: string; overload; function InvertMe: string; overload; end; But when I use it in my code, the TStringHelper in System.StrUtils "gets out" and I can't use it's functions. Is it possible to both of them to coexist? 回答1: At most one helper can active at any one point in your code. The documentation says this: You can define and associate multiple helpers
