建立ViewBase類，重寫INotifyPropertyChanged介面，實現資料更新

public class ViewBase : INotifyPropertyChanged
    {
        [AttributeUsage(AttributeTargets.Parameter, Inherited = false)]
        public class CallerMemberNameAttribute : Attribute
        {

        }
        public event PropertyChangedEventHandler PropertyChanged;
        
 
protected void UpdateProper<T>(ref T properValue, T newValue, [CallerMemberName] string properName = "")
        {
            if (object.Equals(properValue, newValue))
                return;

            properValue = newValue;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(properName));
        }
    }
 

與xaml對應的ViewModel，繼承ViewBase

    public class MainWindowView:ViewBase
    {
        private string stuName;
        public string StuName { get => stuName; set => UpdateProper(ref stuName, value); }
    }

xaml.cs中

        public MainWindow()//構造方法
        {
            InitializeComponent();
            view 
 
= new MainWindowView();
            this.DataContext = view;
        }
        MainWindowView view;//相應的ViewModel物件名

xaml中

<TextBox Text="{Binding StuName}"></TextBox>

若實現雙向繫結則更改UpdateSourceTrigger屬性，該屬性是資料更新的觸發方式

<TextBox Text="{Binding StuName,UpdateSourceTrigger=PropertyChanged}"></TextBox>
