模板10是否实现了INotifyPropertyChanged？

using System.ComponentModel;

public class MyViewModel : INotifyPropertyChanged
{
    private string myProperty;

    public string MyProperty
    {
        get { return myProperty; }
        set
        {
            if (myProperty != value)
            {
                myProperty = value;
                OnPropertyChanged(nameof(MyProperty));
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

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