Delphi 根据字符串找到函数并执行的实例
关键字：MethodAddress：取得方法的地址，这个方法需要是published的。
实例代码：
unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TShowInfo = procedure(info:string) of object; //声明一个procedure类型，参数和ShowInfo一致 TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } published procedure ShowInfo(info:string); end; var Form1: TForm1; implementation {$R *.dfm} { TForm1 } procedure TForm1.ShowInfo(info: string); begin ShowMessage(info); end; procedure TForm1.Button1Click(Sender: TObject); var s:TShowInfo; begin @s := MethodAddress('ShowInfo'); //取得ShowInfo的地址 if @s <> nil then //如果不为空 begin s('中华人民共和国'); //执行 end; end; end. 如有疑问请留言或者到本站社区交流讨论，感谢阅读，希望能帮助到大家，谢谢大家对本站的支持！
