c# - 无法将 json 转换为 xml

Question

我正在尝试将 json 字符串转换为 xml 1) 我的 json 是

[  
       {  
          "QuizTitle":"asdf",
          "QuizImage":"",
          "QuizCategory":"0",
          "QuizTags":"asdf",
          "question":[  
             [  
                {  
                   "QuestionType":"1",
                   "QuestionTitle":"asdf",
                   "questionOption":[  
                      {  
                         "QuestionOptionValue":"sdf",
                         "QuestionOptionIsRight":"0"
                      },
                      {  
                         "QuestionOptionValue":"asdf",
                         "QuestionOptionIsRight":"1"
                      }
                   ]
                }
             ],
             [  
                {  
                   "QuestionType":"2",
                   "QuestionTitle":"sdfdsf",
                   "questionOption":[  
                      {  
                         "QuestionOptionValue":"asdf",
                         "QuestionOptionIsRight":"0"
                      },
                      {  
                         "QuestionOptionValue":"asdf",
                         "QuestionOptionIsRight":"1"
                      }
                   ]
                }
             ]
          ]
       }
    ]

2) 我的 C# 代码是

XmlDocument doc = JsonConvert.DeserializeXmlNode(str);

出现以下错误:

Error:--XmlNodeConverter can only convert JSON that begins with an object.

我尝试在 json 中进行少量编辑，例如 remove [] 问题元素。但没有奏效。

Answer 1

根据Mitchell Skurnik的 comment ，您可以使用 JsonConvert.DeserializeXmlNode(JSONString, "root");。

If your data is an array then you need to do something like this: JsonConvert.DeserializeXmlNode("{"Row":" + json + "}", "root").ToXmlString() otherwise you will get a "XmlNodeConverter can only convert JSON that begins with an object." exception.
