綁定列表到一個ComboBox

Question

我想我的列表綁定到一個ComboBox：

private BindingList<Tool> toolList = new BindingList<Tool>(); 

XAML的綁定：

<ComboBox ItemsSource="{Binding toolList}" DisplayMemberPath="Name" 
    SelectedValuePath="Name" SelectedValue= "{Binding toolList}" Height="22" 
    Name="comboBoxTools" Width="185" SelectionChanged="comboBoxTools_SelectionChanged" /> 

列表的對象有成員名稱和路徑，我想該名稱出現在組合框中。 當我添加一個新的對象添加到列表不顯示在組合框：

public ObservableCollection<Tool> toolList = new ObservableCollection<Tool>(); 
    private void buttonAdd_Click(object sender, RoutedEventArgs e) 
    { 
     InputDialog input = new InputDialog(); 
     input.ShowDialog(); 
     inputNewTool = input.enteredTxt; 

     if (inputNewTool != null) 
     { 
      System.Windows.Forms.MessageBox.Show("Chose the Tool's directory"); 
      dlg.DefaultExt = ".exe"; 
      dlg.Filter = "Application (.exe)|*.exe"; 

      if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK) 
      { 
       Tool tool = new Tool(); 
       tool.Name = inputNewTool; 
       tool.Path = dlg.FileName; 
       toolList.Add(tool); 
       //comboBoxTools.Items.Add(tool); 
      }     
     }    
    } 

XAML的綁定：

<ComboBox ItemsSource="{Binding Path=toolList}" DisplayMemberPath="Name" 
SelectedValuePath="Name" SelectedValue= "{Binding Path=toolList}" Height="22" 
Name="comboBoxTools" Width="185" SelectionChanged="comboBoxTools_SelectionChanged" />
