我想把下面代码中类CAxisItem的属性 PulseDirection 双向绑定到一个 comboBox1上面去，使comboBox1里面有“”正向、反向“”的选项，他的值的改变跟对象AxisItem属性PulseDirection 相互对应，怎么搞啊？
就是下面代码中打问号的部分怎么弄？谢谢了。
=============================
public enum E_DIRECTION
{
DEFAULT,
INVERSE
}
public class CAxisItem : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private E_DIRECTION pulse_direction;
public E_DIRECTION PulseDirection
{
get
{
return pulse_direction;
}
set
{
if (pulse_direction != value)
{
pulse_direction = value;
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs("PulseDirection"));
}
}
}
}
}
public partial class Form1 : Form
{
private BindingList<string> DirectionList = new BindingList<string>();
public BindingList<string> BindingDirectionList
{
get
{
return DirectionList;
}
}
public Form1()
{
InitializeComponent();
DirectionList.Add("正向");
DirectionList.Add("反向");
CAxisItem AxisItem = new CAxisItem();
///???????????????????????????????????????????????
Binding B = new Binding("SelectedItem", AxisItem, "PulseDirection", false, DataSourceUpdateMode.OnPropertyChanged);
comboBox1.DataBindings.Add(B);
B = new Binding("SelectedValue", AxisItem, "PulseDirection", false, DataSourceUpdateMode.OnPropertyChanged);
comboBox1.DataBindings.Add(B);
///???????????????????????????????????????????????
}
}
