推荐答案

不，你不能绑定到变量。


绑定适用于实现的集合一个接口，使得进行绑定的

对象可以将数据输入和输出源

对象。仅仅使用给定的变量就无法完成。

No, you cannot bind to a variable.

Binding works for collections that implement an interface such that the
objects doing the binding can property get data in and out of the source
object. It can''t be done with just a given variable.

???你为什么想要？只需在变量发生变化时更新它。

??? Why would you want to? Just update it when the variable changes.

嗯，你想要的，因为你有20个字段，你不要想要代码

一直手动更新20个变量。出于同样的原因，你想要绑定到一个实际的数据源。

Well, you would want to, because you have 20 fields, and you don''t want code
manually updating the 20 variables all the time. It is for the same reasons
you would want to bind to an actual datasource.
