WPF 在文本框中混合绑定文本和固定文本

使用WPF（Windows Presentation Foundation）框架，我们可以轻松地在文本框中混合绑定文本和固定文本。这为我们提供了更大的灵活性，能够动态地更新文本框中的内容，同时保留一些静态的文本。

public class PersonModel : INotifyPropertyChanged
{

    private int _age;
    public string FirstName
    {
        get { return _firstName; }
        set
        {
            _firstName = value;
            OnPropertyChanged(nameof(FirstName));
        }
    }
    public int Age
    {
        get { return _age; }
        set
        {
            _age = value;
            OnPropertyChanged(nameof(Age));
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        PersonModel person = new PersonModel()
        {
            FirstName = "John",
            Age = 25
        };
        DataContext = person;
    }
