            System.Reflection.PropertyInfo[] properties = t.GetProperties();
            foreach (System.Reflection.PropertyInfo info in properties)
            {
                Console.Write("name=" + info.Name + ";" + "type=" + info.PropertyType.Name + ";value=" + GetObjectPropertyValue<Object>(new object(), info.Name) + "<br />");
            }
        }
    }

 代码使用方法如下：

bool cc = _person.ContainProperty("cc");
bool aa = _person.ContainProperty("Age");
