demo代码：

   string text1 = "";
            string express1 = "required;length[9]";
            AyFormResult result1 = text1.ToAyExpressionFormResult(express1);
            Console.WriteLine();
            Console.WriteLine("原字符串:" + text1);
            Console.WriteLine("AY表单表达式:" + express1);
            if (result1.Result)
                Console.WriteLine("验证结果：通过");
            else
                Console.WriteLine("验证结果：失败!  " + result1.Error);

            string text2 = "helloAY杨洋";

            AyFormResult result2 = text2.ToAyExpressionFormResult(express2);
            Console.WriteLine();
            Console.WriteLine("原字符串:" + text2);
            Console.WriteLine("AY表单表达式:" + express2);
            if (result2.Result)
                Console.WriteLine("验证结果：通过");
            else
