在两个类之间共享列表中的数据

我试图通过外部设置文件在Unity中制作相机。目前，我已经读取了该文件，其值存储如下:

    public struct Entry
{
    public System.Object value;
    public Type type;
}
public class HV_ReadSettingsFile : MonoBehaviour
{
    Entry _screenEntry;
    Entry _cameraEntry;

public Dictionary<string, Entry> cameraDictionary = new Dictionary<string, Entry>();
public List<HV_Camera> cameraList = new List<HV_Camera>();
public List<HV_Screen> screenList = new List<HV_Screen>();


// Use this for initialization
void Start()
{
    StoreXMLValues();
}
// Update is called once per frame
void Update()
{
}
void StoreXMLValues()
{
    var xdoc = XDocument.Load(@"C:''Test.xml");
    var screens = xdoc.Descendants("Screen");
    var cameras = xdoc.Descendants("Camera");

    foreach (var screen in screens)
    {
        HV_Screen _screen = new HV_Screen();
        _screen.Name = (string)screen.Element("Name").Attribute("Name");
        _screen.Tag = (string)screen.Element("ScreenTag").Attribute("Tag");
        _screen.XPOS = (string)screen.Element("LocalPosition").Attribute("X");
        _screen.YPOS = (string)screen.Element("LocalPosition").Attribute("Y");
        _screen.ZPOS = (string)screen.Element("LocalPosition").Attribute("Z");
        _screen.Width = (string)screen.Element("Width").Attribute("Width");
        _screen.Height = (string)screen.Element("Height").Attribute("Height");
        _screen.YAW = (string)screen.Element("Orientation").Attribute("YAW");
        _screen.PITCH = (string)screen.Element("Orientation").Attribute("PITCH");
        _screen.ROLL = (string)screen.Element("Orientation").Attribute("ROLL");

        //Debug.Log("Screen name: " + _screen.Name);
        //Debug.Log("Screen tag: " + _screen.Tag);
        //Debug.Log("Screen xpos: " + _screen.XPOS);
        //Debug.Log("Screen ypos: " + _screen.YPOS);
        //Debug.Log("Screen zpos: " + _screen.ZPOS);
        //Debug.Log("Screen width: " + _screen.Width);
        //Debug.Log("Screen height: " + _screen.Height);
        //Debug.Log("Screen Yaw: " + _screen.YAW);
        //Debug.Log("Screen Pitch: " + _screen.PITCH);
        //Debug.Log("Screen Roll: " + _screen.ROLL);
        screenList.Add(_screen);
    }
    foreach (var camera in cameras)
    {
        HV_Camera _camera = new HV_Camera();
        _camera.Name = (string)camera.Element("Name").Attribute("Name");
        _camera.Tag = (string)camera.Element("CameraTag").Attribute("Tag");
        _camera.XPOS = (string)camera.Element("LocalPosition").Attribute("X");
        _camera.YPOS = (string)camera.Element("LocalPosition").Attribute("Y");
        _camera.ZPOS = (string)camera.Element("LocalPosition").Attribute("Z");
        _camera.YAW = (string)camera.Element("Orientation").Attribute("Yaw");
        _camera.PITCH = (string)camera.Element("Orientation").Attribute("Pitch");
        _camera.ROLL = (string)camera.Element("Orientation").Attribute("Roll");
        _camera.Near = (string)camera.Element("Near").Attribute("Near");
        _camera.Far = (string)camera.Element("Far").Attribute("Far");
        _camera.FOV = (string)camera.Element("FOV").Attribute("FOV");
        _camera.AspectRatio = (string)camera.Element("AspectRatio").Attribute("AspectRatio");
        _camera.ScreenDistance = (string)camera.Element("ScreenDistance").Attribute("ScreenDistance");
       // Debug.Log("Camera name: " + _camera.Name);
        cameraList.Add(_camera);
    }
    //Debug.Log("Camera Count: " + cameraList.Count);
    //Debug.Log("Screen Count: " + screenList.Count);
}
public List<HV_Camera> GetCameraList()
{
   // Debug.Log("Got list");
    return cameraList;
}

我已经用注释掉的Debug进行了测试。日志和我知道我的设置文件正在读取和存储的值。

在我的HV_Camera类中，我试图访问cameraList中的数据。这是我的文件:

     HV_ReadSettingsFile settings;
        List<HV_Camera> testCamera = new List<HV_Camera>();
void Start () 
{
   settings = gameObject.GetComponent<HV_ReadSettingsFile>();
 GetList();
   CreateCamera();
}
// Update is called once per frame
void Update () 
{
}

public void GetList()
{
    testCamera = settings.GetCameraList();

}
public void CreateCamera()
{
    for (int i = 0; i < testCamera.Count; i++)
    {
        Debug.Log("I am camera");
    }

}

现在，在for循环中，我只是想看看数据是否被传递了。如果有效，"我是照相机"应该被打印4次。但事实并非如此。是我遗漏了什么，还是做得不对?
