Just to add something... If you don't put {get; set;} you are creating a Field but if you put the {get; set;} you are creating a Property. Having a property could make some things easier especially when working with Reflection.

如果加了 {get; set;} 那么在创建 Property，如果不加就是在创建 Field。Field 在 Data Binding 的时候不会起作用，必须要用 Property。
