C# 通过DynamicObject让Dictionary可以通过dynamic进行操作

            DynamicDictionary dict = new DynamicDictionary();
            dict.Value["ID"] = 1;
            dict.Value["Name"] = "李二";
            dict.Value["Address"] = "李家坡";

            dynamic dd = dict; //结合动态类型，代码很简洁，但是安全性和性能会下降
            dd.ID = 2; //动态类型可以直接点出属性
            dd.Name = "张三";
            dd.Address = "张家村";
            dd.Birthdate = new DateTime(1989, 9, 23);
            dd.Remark = "测试456";
            foreach (var p in dict.Value) {
                Console.WriteLine(p.Key + ":" + p.Value);
            }
