如何在不使用字符串名称的情况下引发PropertyChanged事件

public class MyPropertyChangedEventArgs<T> : PropertyChangedEventArgs
{
    public MyPropertyChangedEventArgs(Expression<Func<T>> propertyExpression)
        : base(GetPropertyName(propertyExpression))
    {
    }

    private static string GetPropertyName(Expression<Func<T>> propertyExpression)
    {
        MemberExpression memberExpression = (MemberExpression)propertyExpression.Body;
        return memberExpression.Member.Name;
    }
}

private string _myProperty;
public string MyProperty
{
    get { return _myProperty; }
    set
    {
        if (_myProperty != value)
        {
            _myProperty = value;
            RaisePropertyChanged(() => MyProperty);
        }
    }
}

private void RaisePropertyChanged<T>(Expression<Func<T>> propertyExpression)
{
    PropertyChanged?.Invoke(this, new MyPropertyChangedEventArgs<T>(propertyExpression));
}

public event PropertyChangedEventHandler PropertyChanged;

private void OnMyPropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == nameof(MyProperty))
    {
        // 处理MyProperty属性的更改
    }
}
