添加新的项目到一个新的列表

Question

我想在这里结束与FAQData是一个JSON字符串。首先，我有这个简单的类：

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

然后，这就是我不知道该如何处理呢？

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." 
     }, 
    }) 

显然，上面的语法不正确。我一直在玩，并试图搜索各种谷歌，但我似乎无法到达那里。我要的是为FAQData JSON字符串结果是这样的：

[ 
    {"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

您可以创建一个变量列表来操作，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);
