将静态成员访问另一个类不起作用？

Question

我遇到一个问题，当用户选择该特定对象时，我试图访问静态成员以使该消息显示在数据库中。顺便说一下，我的前端正在统一使用它。因此，任何人都可以帮助我解决此问题。谢谢您的帮助。

这是我的代码：

     public  void NextButton()
    {
        if (highlightSet == true)
        {

            var httpWebRequest =
                (HttpWebRequest) WebRequest.Create("https://PROJECT_URL.firebaseio.com/brokenComp.json");
            httpWebRequest.ContentType = "application/json";
            httpWebRequest.Method = "PUT";


            using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
            {


          string missingObjectCount = TextDisplay.Message; 
                streamWriter.Write(missingObjectCount);
            }

            var httpResponse = (HttpWebResponse) httpWebRequest.GetResponse();
            using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
            {
                var result = streamReader.ReadToEnd();

            }

            // When everything is Okay, it will load the scene. 
            SceneManager.LoadScene("Quiz");
        }

        else if (highlightSet == false)
        {
            Transform[] transforms = Selection.GetTransforms(SelectionMode.Deep |
                                                             SelectionMode.ExcludePrefab | SelectionMode.Editable);
            if (transforms.Length > 0 &&
                EditorUtility.DisplayDialog("Select a missing object",
                    "Please find the missing object  "
                    + "of the Headset", "", "OK"))
            {
                foreach (Transform transform in transforms)
                {
                    RaycastHit hit;
                    if (Physics.Raycast(transform.position, -Vector3.up, out hit))
                    {
                        transform.position = hit.point;
                        Vector3 randomized = Random.onUnitSphere;
                        randomized = new Vector3(randomized.x, 0F, randomized.z);
                        transform.rotation = Quaternion.LookRotation(randomized, hit.normal);
                    }
                }
            }

        }
    }

TextDisplay：

    public class TextDisplay: MonoBehaviour
{

   public static string Message;

 }

OBClick：

     public void OnPointerClick(PointerEventData eventData)
    {

        if (!BlowupController.RemoveStatus)
        {
            EventSystem eventSystem = EventSystem.current;
            var RIM = (ReticleInputModule)eventSystem.gameObject.GetComponent(typeof(ReticleInputModule));
            GameObject tmp = GameObject.Find("Reticle Text");
           var ob = (TextDisplay)gameobj.GetComponent(typeof(TextDisplay));

            if (tmp == null)
            {
                GameObject TextGO = new GameObject("Reticle Text");
                Text txt = TextGO.gameObject.AddComponent<Text>(); 
              // txt.text = ob.Message; 
              txt.text = TextDisplay.Message;
               txt.font = Resources.GetBuiltinResource(typeof(Font), "Arial.ttf") as Font;
                txt.fontSize = 20;
                txt.color = Color.white;
                txt.alignment = TextAnchor.MiddleCenter;
                TextGO.transform.SetParent(RIM.reticle.transform);
                TextGO.transform.localPosition = new Vector3(0f, -80f, -1.2f);
                TextGO.transform.localScale = new Vector3(1f, 1f, 1f);
                TextGO.transform.localRotation = new Quaternion(0f, 0f, 0f, 0f);
                RectTransform rt = TextGO.GetComponent(typeof(RectTransform)) as RectTransform;
                rt.sizeDelta = new Vector2(500, 30);
            }
            else
            {
                Text txt = tmp.GetComponent<Text>(); 
             //  txt.text = ob.Message;
             txt.text = TextDisplay.Message; 



            }
        }
        else
        {
            BlowupController.UndoList.Add(gameobj);
            gameobj.SetActive(false);
        }
    }
}

如果您从Web请求中收到404错误，这是因为Firebase无法找到您请求的资源。确保您的URL（https://PROJECT_URL.firebaseio.com/brokenComp.json）是正确的。
