循环遍历结构内部存在的属性内部的值

Question

我创建了一个结构，它具有一些属性，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 DeviceDetailModel.DT854P

但问题是我会在运行时获得一个值，我必须使用它来确定我必须返回哪个结构属性

例如 = 我的运行时值是 853P 我想循环遍历我的结构来确定DeviceName 中的哪个位置与这个值853P 匹配，哪个应该返回DeviceDetailModel.DT83P

我能够遍历结构的属性，但无法获取值

编辑：根据我的运行时值，我需要迭代 DeviceName 的值，如果值匹配，它应该返回关联的属性

这是一个相当简单的选择：

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 的返回值是 Nullable<DeviceDetailModel>，所以如果您正在寻找一个未找到的字符串，您不会得到异常，但 null。
