一、用属性代替可访问的字段 1、.NET数据绑定只支持数据绑定，使用属性可以获得数据绑定的好处； 2、在属性的get和set访问器重可使用lock添加多线程的支持。 二、readonly（运行时常量）和const（编译时常量） 1、const只可用于基元类型、枚举、字符串，而readonly则可以是任何的类型； 2、const在编译时将替换成具体的常量，这样如果在引用中同时使用了const和readonly两种值，则对readonly的再次改变将会改变设计的初衷，这是需要重新编译所更改的程序集，以重新引用新的常量值。 3、const比readonly效率高，但失去了应用的灵活性。 三、... 阅读全文
