WPF中model属性即时改变

public class Test:INotifyPropertyChanged 
    {
        private string name;

        public string Name
        {
            get { return this.name; }
            set 
            {
                this.name = value;
                NotifyPropertyChanged("Name");
            }
        }

        public event PropertyChangedEventHandler PropertyChanged;
        private void NotifyPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }
