如何使用PropertyChanged将最新输入与初始值进行比较？

private string _name;
public string Name
{
    get { return _name; }
    set
    {
        if (_name != value)
        {
            string oldValue = _name;
            _name = value;
            OnPropertyChanged("Name", oldValue, value);
        }
    }
}

public event PropertyChangedEventHandler PropertyChanged;

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

public void HandlePropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == "Name")
    {
        string oldValue = ((YourClassName)sender).Name; // 获取旧值
        string newValue = ((YourClassName)sender).Name; // 获取新值

        // 进行比较操作
        // ...
    }
}
