添加新的項目到一個新的列表

Question

我想在這裏結束與FAQData是一個JSON字符串。首先，我有這個簡單的類：

public class FAQData 
{ 
    public string FAQQuestion { get; set; } 
    public string FAQAnswer { get; set; } 
} 

然後，這就是我不知道該如何處理呢？

var faqData = JsonConvert.SerializeObject(new List<FAQData> 
    { 
     { 
      FAQQuestion = "Question 1?", 
      FAQAnswer = "This is the answer to Question 1." 
     }, 
     { 
      FAQQuestion = "Question 2?", 
      FAQAnswer = "This is the answer to Question 2." 
     }, 
    }) 

顯然，上面的語法不正確。我一直在玩，並試圖搜索各種谷歌，但我似乎無法到達那裏。我要的是爲FAQData JSON字符串結果是這樣的：

[ 
    {"FAQQuestion": "Question 1?", "FAQAnswer": "This is the answer to Question 1."}, 
    {"FAQQuestion": "Question 2?", "FAQAnswer": "This is the answer to Question 2."} 
] 

Answer 1

你忘new FAQData()：

JsonConvert.SerializeObject(new List<FAQData> 
{ 
    new FAQData() 
    { 
     FAQQuestion = "Question 1?", 
     FAQAnswer = "This is the answer to Question 1." 
    }, 
    new FAQData() 
    { 
     FAQQuestion = "Question 2?", 
     FAQAnswer = "This is the answer to Question 2." 
    }, 
}); 

Answer 2

您可以創建一個變量列表來操作，序列化到JSON之前。

  var faqList = new List<FAQData> 
      { 
       new FAQData() 
       { 
        FAQQuestion = "Question 1?", 
        FAQAnswer = "This is the answer to Question 1." 
       }, 
       new FAQData() 
       { 
        FAQQuestion = "Question 2?", 
        FAQAnswer = "This is the answer to Question 2." 
       }, 
      }; 
      faqList.Add(new FAQData() 
      { 
       FAQQuestion = "Question 3?", 
       FAQAnswer = "This is the answer to Question 3." 
      }); 
      var faqData = JsonConvert.SerializeObject(faqList);
