WPF使用绑定的结果作为XAML中的输入字符串

<Window x:Class="YourNamespace.YourWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Your Window" Height="450" Width="800">
    <Grid>
        <TextBox Text="{Binding YourProperty}" />
        <Button Content="Submit" Click="Button_Click" />
    </Grid>
</Window>

public class YourViewModel : INotifyPropertyChanged
{
    private string yourProperty;

    public string YourProperty
    {
        get { return yourProperty; }
        set
        {
            yourProperty = value;
            OnPropertyChanged(nameof(YourProperty));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

public partial class YourWindow : Window
{
    public YourWindow()
    {
        InitializeComponent();
        DataContext = new YourViewModel();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        // 使用绑定的结果（YourProperty）进行其他操作
        string inputString = ((YourViewModel)DataContext).YourProperty;
        // ...
    }
}
