c# - 如何在c#中将xml数据转换为json

Question

我想将 xml 数据转换为 json

 [WebMethod]
 [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
 public DataTable NameArray()
 {
   DataTable imageTable = new DataTable("gcm");
   // imageTable.Columns.Add("image_name", typeof(String));
   imageTable.Columns.Add("username", typeof(String));
   imageTable.Columns.Add("gcmkey", typeof(String));
   if (con.State.ToString() == "Closed")
   {
     con.Open();
   }
   string query = "SELECT username,gcmkey from gcm";
   SqlCommand command = new SqlCommand(query, con);
   SqlDataReader reader = command.ExecuteReader();
   if (reader.HasRows)
   {
     while (reader.Read())
     {
       imageTable.Rows.Add(reader["username"],reader["gcmkey"]);
     }
   }
   reader.Close();
   con.Close();
   return imageTable;
 }

我正在使用这条线，但它对我不起作用，所以请告诉我如何转换为 json

this.Context.Response.ContentType = "application/json; charset=utf-8";
this.Context.Response.Write(json.Serialize(new { PersonalProfile = reader })); 

输出:-

DataTable xmlns="http://tempuri.org/">
<xs:schema xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" id="NewDataSet">

是的。使用包含辅助方法的 JsonConvert 类来实现此精确目的:

// To convert an XML node contained in string xml into a JSON string   
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
string jsonText = JsonConvert.SerializeXmlNode(doc);

// To convert JSON text contained in string json into an XML node
XmlDocument doc = JsonConvert.DeserializeXmlNode(json);
