遍历结构中存在的属性中的值

Question

我创建了一个具有一些属性的结构，例如

public struct DeviceDetailModel
{
  public static readonly DeviceDetailModel DT851P = new DeviceDetailModel("851P","v1","v2");
  public static readonly DeviceDetailModel DT852P = new DeviceDetailModel("852P","v3","v4");
  public static readonly DeviceDetailModel DT83P = new DeviceDetailModel("853P","v5","v6");
  public static readonly DeviceDetailModel DT854P = new DeviceDetailModel("854P");


 public string DeviceName { get; private set; }
 public string Value1 { get; private set; }
 public string Value2 { get; private set; }

 private DeviceDetailModel(string deviceName,string value1,string value2)
 {
  DeviceName = deviceName;
  Value1 = value1;
  Value2 = value2;
 }
}

现在，如果我想获得单个项目的详细信息，我只需要做 DeviceDetailModel.DT854P

但问题是我会在运行time 上获得一个值，我必须使用它来确定我必须 return

哪个结构属性

例如=我的运行时间值是853P 我想循环遍历我的结构以确定 DeviceName 中的何处与该值 853P 匹配以及哪个应该 return DeviceDetailModel.DT83P

我能够遍历结构的属性，但无法获取值

编辑：根据我的运行时间值，我需要迭代 DeviceName 的值，如果该值匹配，它应该 return 关联属性

Answer 1

这是一个相当简单的选项：

public struct DeviceDetailModel
{
    private static readonly Dictionary<string, DeviceDetailModel> models = new Dictionary<string, DeviceDetailModel>
    {
        {"851P", new DeviceDetailModel("851P")},
        {"852P", new DeviceDetailModel("852P")},
        {"853P", new DeviceDetailModel("853P")},
        {"854P", new DeviceDetailModel("854P")},
    };

    public static DeviceDetailModel DT851P get => models["851P"];
    public static DeviceDetailModel DT852P get => models["852P"];
    public static DeviceDetailModel DT83P get => models["853P"];
    public static  DeviceDetailModel DT854P get => models["854P"];

    private DeviceDetailModel(string deviceName)
    {
        DeviceName = deviceName;
    }

    public string DeviceName {get;private set;}

    public DeviceDetailModel? FindByDeviceName(string deviceName)
    {
        return models.TryGetValue(deviceName, out var value) ? value : (DeviceDetailModel)null;
    }
}

请注意，FindByDeviceName 的 return 值是 Nullable<DeviceDetailModel>，因此如果您要查找未找到的字符串，您不会得到异常，但 null.
