Silverlight 中 Notify 的常用写法

Silverlight 中 Notify 的两种常用写法，哪种更好用，你懂的。

#region INotifyPropertyChanged

public event PropertyChangedEventHandler PropertyChanged;

public void Notify(string name)
{
if (PropertyChanged != null)
        PropertyChanged(this, new PropertyChangedEventArgs(name));
}

public void Notify<T>(Expression<Func<T>> exp)
{
var memberExpression = exp.Body as MemberExpression;
if (memberExpression != null)
        Notify(memberExpression.Member.Name);
}

#endregion

应用示例：

private string _name = string.Empty;
public string Name
{
get { return _name; }
set
    {
        _name = value;
        Notify(() => Name);
    }
}

private int _age;
public int Age
{
get { return _age; }
set
    {
        _age = value;
        Notify("Age");
    }
}
