Question

我正在尝试为我正在处理的程序找出ViewModel。我以前没有这样做过。以下是Switch对象的部分类定义，它需要ViewModel和我到目前为止的XAML。我知道XAML需要更多。

现在我正在进行代码隐藏，以便在我打开它之前用SwitchBrowser窗口填充数据。我知道将ObservableCollection绑定到XAML会更容易。

我可以在CiscoSwitch中存储ObservableCollection对象并直接绑定到Switch对象上的属性吗？

如果是这样，我是否可以将{XAML中的ItemsSource上的ModulesTreeview设置为ModulesList上的CiscoSwitch？现在我在代码隐藏中使用foreach来填充ModulesTreeView。

或者，我会为ObservableCollection创建SwitchModules，然后为VSANs创建另一个，依此类推吗？

 public partial class CiscoSwitch
{
    #region baseswitchclassproperties
    private string _SwitchName = String.Empty;
    public string switchName{ get{return _SwitchName;} set{_SwitchName=value;} }        private string _SWVersion = String.Empty;
    public  string swVersion{ get{return _SWVersion;} set{_SWVersion=value;} }
    private string _SwitchModel = String.Empty;
    public string switchModel { get{return _SwitchModel;} set{_SwitchModel=value;} }
    private string _SerialNumber = String.Empty;
    public string SerialNumber { get { return _SerialNumber; } set { _SerialNumber = value; } }
    private string _SwitchWWPN = string.Empty;
    public string SwitchWWPN { get { return _SwitchWWPN; } set { _SwitchWWPN = value; } }
    public Dictionary<int, SwitchModule> ModuleList = new Dictionary<int, SwitchModule>();
    public Dictionary <int, CiscoVSAN> VSANList = new Dictionary<int, CiscoVSAN>();
    protected EthernetPort _ManagementPort = new EthernetPort();
    public string IPAddress{ set{_ManagementPort.IPAddress=value;} get{return _ManagementPort.IPAddress;} }

    public string LastDataCaptureDate = null;
    public Dictionary<int, PortChannel> PortChanelList = new Dictionary<int, PortChannel>();
    public Dictionary<String, FCIPPort> FCIPPortList = new Dictionary<string, FCIPPort>();
    public InterVSANTopology IVRTopology =  null; //new InterVSANTopology();

    public Dictionary<int, List<CiscoSwitch>> NeighborsList = new Dictionary<int, List<CiscoSwitch>>();
    public Dictionary<string, string> DeviceAliases = new Dictionary<string, string>();
    public Dictionary<string, FCPort> FlogiDatabase = new Dictionary<string, FCPort>();
    #endregion
}

XAML：

<Window.Resources>
    <Style TargetType="{x:Type TreeViewItem}" x:Key="ModuleStyle">
        <Setter Property="Foreground" Value="Blue"/>
        <Setter Property="FontSize" Value="12"/>

Answer 1

关于创建单个ObservableCollection<CiscoSwitch>的第一个想法是正确的方法。这是一个更简化的示例，您可以根据自己的特定需求进行扩展。

public class Person
{
    public string Name { get; set; }
    public string Address { get; set; }
}

假设我们的ViewModel中有一个名为ObservableCollection<Person>的{{1}}。

People

这是一个过于简单的示例，但我认为您应该能够将其扩展到您的需求。希望这有帮助！
