如何在更改值时更改彼此的文本框(MVVM)

using System.ComponentModel;

public class MainViewModel : INotifyPropertyChanged
{
    private string _text1;
    private string _text2;

    public string Text1
    {
        get => _text1;
        set
        {
            if (_text1 != value)
            {
                _text1 = value;
                OnPropertyChanged(nameof(Text1));
                Text2 = value; // 当Text1改变时，更新Text2
            }
        }
    }

    public string Text2
    {
        get => _text2;
        set
        {
            if (_text2 != value)
            {
                _text2 = value;
                OnPropertyChanged(nameof(Text2));
                Text1 = value; // 当Text2改变时，更新Text1
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

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