如何將 StringContent() 類型轉換為類型的對象<MyModelClass>在 C# 中使用 Visual Studio 2019

Question

我正在嘗試將下面第一行代碼中的字符串結果轉換為“Root.cs”類型的對象。 我在我的 Visual Studio 2019“解決方案”中設置了“Root.cs”類，並設置了適當的類以將字符串結果轉換為對象。

這行代碼可以很好地得到我需要的字符串：

var result = client.PostAsync(endpoint, payload).Result.Content.ReadAsStringAsync().Result;

這是字符串“結果”的內容：

    {"sections":[{"id":"Building_Configuration","name":"Building_Configuration","sections":[{"id":"B    uilding_Configuration.Parameters_SP","name":"Building_Configuration.Parameters_SP","sectio      ns":[],"variables":[{"id":"Building_Configuration.Parameters_SP.fixtureStrategy_SP","name":"Bui lding_Configuration.Parameters_SP.fixtureStrategy_SP","valueType":"String","distinctValueCou    nt":3.0,"allowMultipleAssignments":false,"values":[{"name":"ETA","value":"ETA","properties":[{  "id":"fullyqualifiedname","value":"ETA","type":"String"},{"id":"name","value":"ETA","type":"Stri    ng"}],"type":"SingletonValue","assigned":"byDefault","incompatible":false},{"name":"ETD","valu  e":"ETD","properties":[{"id":"fullyqualifiedname","value":"ETD","type":"String"},{"id":"name","v    alue":"ETD","type":"String"}],"type":"SingletonValue","incompatible":false},{"name":"ETA/ETD",  "value":"ETA/ETD","properties":[{"id":"fullyqualifiedname","value":"ETA/ETD","type":"String"},{ "id":"name","value":"ETA/ETD","type":"String"}],"type":"SingletonValue","incompatible":false}],"

現在，我需要創建“根”類型的對象（我的模型類），以便從中挑選某些值。 這條線不應該為此工作嗎？

Root MyObject = JsonConvert.DeserializeObject<Root>(result);

這是 Root.cs 的定義：

public class Root

我的“結果”和“Root.cs”類都大於此處的 30,000 個字符限制。 所以，我只需要發布我的字符串“result”和“Root.cs”類的一部分。 我試圖簡化這個問題。 在我學習如何使用它時請原諒我...

Answer 1

回答：我犯了一個新手錯誤，試圖將我從“Root.cs”模型類中挑選出來的字符串作為 Root 對象返回。 我將方法的返回類型設置為 Root 而不是字符串。 將返回類型更改為字符串后，我的解決方案的那部分工作正常。

它像這樣工作正常：

public string CreateExecPost(FormData person2){

            var payload = new StringContent(newPost, Encoding.UTF8, "application/json");
        
        var result = client.PostAsync(endpoint, payload).Result.Content.ReadAsStringAsync().Result;//result is already in JSON

        Root MyObject = JsonConvert.DeserializeObject<Root>(result);

        //return MyObject.language; //WORKS
        return MyObject.language;
 }
