WPF绑定同一类的两个对象

Question

我有一堂课：

public class Person {

    public string Name { set; get; }

}

我从那个班级实例化了 2 个人：

Person person1 = new Person() { Name="Test1" };

Person person2 = new Person() { Name="Test2" };

在我的 Window.xaml 中，我有两个文本框，我想将它们与两个人对象绑定

<Grid>

    <TextBox />

</Grid>

<Grid>

    <TextBox/>

</Grid>

但我是 WPF 的新手，不知道该怎么做。

我试过了

<Grid DataContext="{Binding person1}">

    <TextBox Text="Binding Name"/>

</Grid>

<Grid DataContext="{Binding person2}">

    <TextBox Text="Binding Name"/>

</Grid>

没用。试过了

<Grid>

    <TextBox Text="Binding person1.Name"/>

</Grid>

<Grid>

    <TextBox Text="Binding person2.Name"/>

</Grid>

没用。

我可以绑定一个人在 Window1.cs 中设置 DataContext

但我不能（或不知道如何）将 2 人设置为 Window1 中的 DataContex。

请首先像这样设置数据上下文。Person person1 = new Person() { Name="Test1" };Person person2 = new Person() { Name="Test2" };DataContext =&nbsp; new&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{&nbsp; Person1 = person1,&nbsp; Person2 = person2&nbsp;};在像这样设计侧绑定数据之后。<Grid>&nbsp; &nbsp; <TextBox Text="{Binding Person1.Name,Mode=TwoWay,&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; UpdateSourceTrigger=PropertyChanged}"/></Grid><Grid>&nbsp; &nbsp; <TextBox Text="{Binding Person2.Name,Mode=TwoWay,&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; UpdateSourceTrigger=PropertyChanged}"/></Grid>或（您只能像这样在设计方面进行更改）<Grid DataContext="{Binding person1}">&nbsp; &nbsp; <TextBox Text="{Binding Name,Mode=TwoWay,&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; UpdateSourceTrigger=PropertyChanged}"/></Grid><Grid DataContext="{Binding person2}">&nbsp; &nbsp; &nbsp; <TextBox Text="{Binding Name,Mode=TwoWay,&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; UpdateSourceTrigger=PropertyChanged}"/></Grid>
