读取一个类的所有属性：

PropertyInfo[] strs = new XYS().GetType().GetProperties();

常用属性

 PropertyInfo prop = strs[0];
 string str =  prop.Name;//属性名
 bool bl = prop.CanRead;//是否可读
 bool bl1 = prop.CanWrite;//是否可写
 string str1 = prop.PropertyType.Name;//数据类型
 bool bl2 = prop.PropertyType.IsArray;//是否为数组
 bool bl3 = prop.PropertyType.IsEnum;//是否是枚举
