通过方法名称，调用方法，并传参数！  

 

TStringExec = procedure(const Value:String) of object;

 procedure TBaseClass.ExecMethod(Sender:TObject;methodName: string;const value:string);

var

   Routine: TMethod;

   Exec: TStringExec;

begin

    Routine.Data := Pointer(Sender) ;

   Routine.Code := self.MethodAddress(MethodName) ;

   if NOT Assigned(Routine.Code) then Exit;

   Exec := TStringExec(Routine) ;

   Exec(value);

end;
