x：绑定和绑定之间的区别 [英] Difference between x:Bind and Binding

问题描述

当我在xaml中使用x：Bind绑定数据时，它可以工作，但是当使用Binding代替x：Bind执行相同的代码时，则不能。为什么会这样？我读过他们的区别，说一个是运行时，其他是编译时之类的东西，但这根本无济于事。谁能在实践上帮助我？

When I bind data using x:Bind in my xaml it works, but when the same code is executed using Binding in place of x:Bind, it doesn't. Why does this happen ?? I have read their difference saying one is runtime and other compile time and stuff like that but that doesn't help at all. Can anyone help me on a practical level??

推荐答案

使用x：bind只能绑定模型类实例的成员。

using x:bind you can bind only a member of model class instance.

 //sends whole current instance to the converter.
//(note: yes you see correct. no property is attached after Binding keyword
  ....
<DataTemplate x:DataType="Models:Human">
<StackPanel Background="{Binding Converter={StaticResource UnwantedDayColorConverter}}">
 ....

通过绑定，您只能绑定模型类instance
的成员

，也可以绑定整个实例（当前对象，而不仅仅是其单个属性）

via Binding you can bind only a member of model class instance
and also you can bind whole instance (current object. not just its single property)

 //you can send only instance property (Gender) to the converter
 <DataTemplate x:DataType="Models:Human">
                <StackPanelHorizontalAlignment="Stretch" Background="{x:Bind Gender, Converter={StaticResource UnwantedDayColorConverter}}">
