Question

我遇到一个问题，我要从我的rest api返回一个完整的guid，但是我只想让getMessage可以动态显示，而不是对其进行硬编码。谁能帮我解决这个问题。谢谢您的帮助。

我的孩子名字在guid上方

Json：

      {
    "42f6be79-443b-4845-8549-865af9e74988": {
        "Active": true,
        "CompletedMessage": "Placeholder",
        "CreatedBy": "",
          "Description": "Placeholder",
        "DisplayName": "Placeholder1",
        "ID": "be193200-c277-48bd-90ab-796e869f2e0b",
        "QuestionsIDs": [
            "bd341962-6c7f-459d-88ea-86aa7186840a",
            "bd341962-6c7f-459d-88ea-86aa7186840a"
        ],
         "WelcomeMessage": "Placeholder3"
    }
}

代码：

        public Text welcomeMessage; 
private async void welcomeMessage()
    {
        Dictionary<string, Questions> questionDictionary = new Dictionary<string, Questions>();

        string json = @"{https://PROJECT_URL.firebaseio.com/Tests/WelcomeMessage.json";

         questionDictionary = JsonConvert.DeserializeObject<Dictionary<string, Questions>>(json);

        foreach (Questions question in questionDictionary.Values)
        {
            Guid[] guids = question.QuestionsIDs; 
            string welcomeMessage = question.WelcomeMessage;

            welcomeMessageShown = GetComponent<Text>();
            welcomeMessageShown.text = welcomeMessage.ToString();

        }

首先创建一个与您的对象匹配的类。可以说Question

  public partial class Question
  {
        [JsonProperty("Active")]
        public bool Active { get; set; }

        [JsonProperty("CompletedMessage")]
        public string CompletedMessage { get; set; }

        [JsonProperty("CreatedBy")]
        public string CreatedBy { get; set; }

        [JsonProperty("Description")]
        public string Description { get; set; }

        [JsonProperty("DisplayName")]
        public string DisplayName { get; set; }

        [JsonProperty("ID")]
        public Guid Id { get; set; }

        [JsonProperty("QuestionsIDs")]
        public Guid[] QuestionsIDs { get; set; }

        [JsonProperty("WelcomeMessage")]
        public string WelcomeMessage { get; set; }
 }

由于我们的json是键值对，因此我们需要deserialize将其保存为字典

我们的词典定义为

 Dictionary<string, Question> questionDictionary = new Dictionary<string, Question>();

现在使用Newtonsoft.Json，我们可以将其反序列化到字典中。

string json = @"{
                  '42f6be79-443b-4845-8549-865af9e74988': {
                     'Active': true,
                     'CompletedMessage': 'Placeholder',
                     'CreatedBy': '',
                     'Description': 'Placeholder',
                     'DisplayName': 'Placeholder1',
                     'ID': 'be193200-c277-48bd-90ab-796e869f2e0b',
                     'QuestionsIDs': [
                          'bd341962-6c7f-459d-88ea-86aa7186840a',
                          'bd341962-6c7f-459d-88ea-86aa7186840a'
                       ],
                      'WelcomeMessage': 'Placeholder3'
                      }
                    }";

 Dictionary<string, Question> questionDictionary = JsonConvert.DeserializeObject<Dictionary<string, Question>>(json);

 foreach (Question question in questionDictionary.Values)
 {
       Guid[] guids = question.QuestionsIDs; // Do whatever you want with it
       string welcomeMessage = question.WelcomeMessage;
 }

如何在C＃中动态显示欢迎消息？
