如何在 wpf UserControl 中参数化绑定？

Question

我有一个 wpf Window ( MyWindow)，它DataContext设置为MyViewModel视图模型类：我的窗口.xaml<Window x:Class="MyProject.MyWindow"      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"       xmlns:d="http://schemas.microsoft.com/expression/blend/2008"      mc:Ignorable="d">      <MyUserControl Text="{Binding MyText, Mode=TwoWay}" /></Window>我的窗口.xaml.cspublic class MyWindow : Window{    MyWindow()    {       InitializeComponent();       DataContext = new MyViewModel();    }}视图模型.cs// MyViewModel implements IPropertyChangedpublic class MyViewModel : INotifyPropertyChanged{    public string MyText { get { ... } set { ... } }    ...}我想将MyText属性的绑定传递MyWindow给以下 UserControl ( MyUserControl)：我的用户控件.xaml<UserControl x:Class="MyProject.MyUserControl"             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"              xmlns:d="http://schemas.microsoft.com/expression/blend/2008"              mc:Ignorable="d">    <StackPanel>        <TextBox            Name="MainTextBox"            Text="{Binding Text, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True, NotifyOnValidationError=True}"          />    </StackPanel></UserControl>我的用户控件.xaml.cspublic partial class MyUserControl : UserControl    {        public static readonly DependencyProperty TextProperty = DependencyProperty.Register(            "Text",            typeof(string),            typeof(MyUserControl),            new UIPropertyMetadata(TextPropertyChangedHandler)        );我想获得在键入的内容Textbox下MyUserControl进入MyViewModel.MyText。如何做到这一点？我试图绑定MyText到Text财产MyUserControl和随后的结合Text中TextBox，以Text从MyUserControl但这并不工作。
