This is the Form data i am receiving in C# using
string data=Request.Form("data");
Now data is nested how can i get the values of data object. Parsing it in json using JsonConvert.Deserialize is throwing exception.

Deserializing JSON objects, keep getting errors (C#)

I am trying to deserialize my json code. The json code is in a string, and the json code looks like this (so I'm assuming it's json objects)
{
"post_id":13,
"thread_id":9,
"user_id":1,
"username":"Username",
"post_date":1496439611,
"message":"testzilla - 2133746943A9",
"ip_id":698,
"message_state":"visible",
"attach_count":0,
"position":0,
"likes":0,
"like_users":"a:0:{}",
"warning_id":0,
"warning_message":"",
"last_edit_date":1496476199,
"last_edit_user_id":0,
"edit_count":9,
"node_id":34,
"title":"Test",
"tags":"a:0:{}",
"node_title":"test node",
"node_name":null,
"message_html":"testzilla - 2133746943A9",
"absolute_url":"url"
}
How would I put the "message" container inside a string? So that the string would contain "testzilla - 2133746943A9" without the quotation marks. I am using JSON.Net
The name of the string that contains this json code is "MACs". Thanks in advance. PS: I am a new coder.

there is a missing "{" at the beginning of your json file, try adding it

You need to create your c# class to deserialize your json string. As per your json structure i have created your class given below
public class MyClass
{
public int post_id { get; set; }
public int thread_id { get; set; }
public int user_id { get; set; }
public string username { get; set; }
public int post_date { get; set; }
public string message { get; set; }
public int ip_id { get; set; }
public string message_state { get; set; }
public int attach_count { get; set; }
public int position { get; set; }
public int likes { get; set; }
public string like_users { get; set; }
public int warning_id { get; set; }
public string warning_message { get; set; }
public int last_edit_date { get; set; }
public int last_edit_user_id { get; set; }
public int edit_count { get; set; }
public int node_id { get; set; }
public string title { get; set; }
public string tags { get; set; }
public string node_title { get; set; }
public object node_name { get; set; }
public string message_html { get; set; }
public string absolute_url { get; set; }
}
No need to use library JSON.Net. You can do this by simply using System.Web.Script.Serialization to deserialize the json string.
Note : System.Web.Script.Serialization is available inside System.Web.Extensions namespace.
Below is the complete code. I kept your json data inside a file named as "test2.json" and consuming it from that file.
using System;
using System.Web.Script.Serialization;
using System.IO;
namespace DesrializeJson1ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var jsonFile = "test2.json";
string jsonstring = File.ReadAllText(jsonFile);
var serializer = new JavaScriptSerializer();
MyClass aClass = serializer.Deserialize<MyClass>(jsonstring);
Console.WriteLine("--------------------------");
Console.WriteLine("message :" + aClass.message);
Console.WriteLine("message_state :" + aClass.message_state);
Console.WriteLine("warning_message :" + aClass.warning_message);
Console.WriteLine("message_html :" + aClass.message_html);
Console.WriteLine("--------------------------");
Console.Read();
}
}
public class MyClass
{
public int post_id { get; set; }
public int thread_id { get; set; }
public int user_id { get; set; }
public string username { get; set; }
public int post_date { get; set; }
public string message { get; set; }
public int ip_id { get; set; }
public string message_state { get; set; }
public int attach_count { get; set; }
public int position { get; set; }
public int likes { get; set; }
public string like_users { get; set; }
public int warning_id { get; set; }
public string warning_message { get; set; }
public int last_edit_date { get; set; }
public int last_edit_user_id { get; set; }
public int edit_count { get; set; }
public int node_id { get; set; }
public string title { get; set; }
public string tags { get; set; }
public string node_title { get; set; }
public object node_name { get; set; }
public string message_html { get; set; }
public string absolute_url { get; set; }
}
}
OUTPUT

You can use regex to get the value you want.
string yourJsonString = #"{ ""post_id"":13, ""thread_id"":9, ""user_id"":1, ""username"":""Username"", ""post_date"":1496439611, ""message"":""testzilla - 2133746943A9"", ""ip_id"":698, ""message_state"":""visible"", ""attach_count"":0, ""position"":0, ""likes"":0, ""like_users"":""a:0:{}"", ""warning_id"":0, ""warning_message"":"""", ""last_edit_date"":1496476199, ""last_edit_user_id"":0, ""edit_count"":9, ""node_id"":34, ""title"":""Test"", ""tags"":""a:0:{}"", ""node_title"":""test node"", ""node_name"":null, ""message_html"":""testzilla - 2133746943A9"", ""absolute_url"":""url""}";
string value = System.Text.RegularExpressions.Regex.Match(yourJsonString,#"""message"":(.+?),").Groups[1].Value.Replace(#"""","");
MessageBox.Show(value);

You can also use dynamic type for deserialization. You will no need to write object for deserialization:
var str = "{\r\n \"post_id\":13,\r\n \"thread_id\":9,\r\n \"user_id\":1,\r\n \"username\":\"Username\",\r\n \"post_date\":1496439611,\r\n \"message\":\"testzilla - 2133746943A9\",\r\n \"ip_id\":698,\r\n \"message_state\":\"visible\",\r\n \"attach_count\":0,\r\n \"position\":0,\r\n \"likes\":0,\r\n \"like_users\":\"a:0:{}\",\r\n \"warning_id\":0,\r\n \"warning_message\":\"\",\r\n \"last_edit_date\":1496476199,\r\n \"last_edit_user_id\":0,\r\n \"edit_count\":9,\r\n \"node_id\":34,\r\n \"title\":\"Test\",\r\n \"tags\":\"a:0:{}\",\r\n \"node_title\":\"test node\",\r\n \"node_name\":null,\r\n \"message_html\":\"testzilla - 2133746943A9\",\r\n \"absolute_url\":\"url\"\r\n}";
dynamic obj = JsonConvert.DeserializeObject(str);
var postId = obj.post_id;
Console.WriteLine("postId:" + postId);
output:
postId:13

how to collect dataset in dataobject?

I want to collect the information of this Json:
{"name":"Maltarya","race":"Sylvari","gender":"Female","profession":"Thief","level":80,"equipment":[{"id":4483,"slot":"HelmAquatic","upgrades":[24723]},{"id":59,"slot":"Backpack","upgrades":[24498],"skin":2381},{"id":11805,"slot":"Coat","upgrades":[24815]},{"id":11889,"slot":"Boots","upgrades":[24723]},{"id":11847,"slot":"Gloves","upgrades":[24815]},{"id":11973,"slot":"Helm","upgrades":[24815]},{"id":11763,"slot":"Leggings","upgrades":[24815]},{"id":11931,"slot":"Shoulders","upgrades":[24815]},{"id":39141,"slot":"Accessory1","upgrades":[24545]}]}
But i have an error when i want to collect the equipment informations.
My code is:
WebRequest request = WebRequest.Create("https://api.guildwars2.com/v2/characters/" + name + "?access_token=" + key);
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
Personnages perso = JsonConvert.DeserializeObject<Personnages>(responseString);
and my Personnages class:
class Personnages
{
public string name { get; set; }
public string race { get; set; }
public string gender { get; set; }
public string profession { get; set; }
public string level { get; set; }
public IList<string> equipment { get; set; }
}
The exception i have is: Unexpected token: Error reading string. StartObject.

You are trying to deserialize JSON array to a IList<string>. However, this array contains objects, but not strings.
You need to implement another one class for these objects and use it in deserialization:
class EquipmentItem
{
public int id { get; set; }
public string slot { get; set; }
public List<int> upgrades { get; set; }
}
class Personnages
{
public string name { get; set; }
public string race { get; set; }
public string gender { get; set; }
public string profession { get; set; }
public string level { get; set; }
public List<EquipmentItem> equipment { get; set; }
}
Personnages perso = JsonConvert.DeserializeObject<Personnages>(responseString);

Deserialize xml xmpp message to object

I'm trying to deserialize a xml string to a c# object. This is the message:
<message from='test1#localhost' to='test2#localhost'><result xmlns='urn:xmpp:mam:tmp' id='A6QV1I4TKO81'><forwarded xmlns='urn:xmpp:forward:0'><delay xmlns='urn:xmpp:delay' from='test1#localhost' stamp='2015-07-21T09:12:09Z'></delay><message type='mchat'><subject/><body/></message></forwarded></result></message>
And this is the class
public class Delay {
[XmlAttribute(AttributeName="xmlns")]
public string Xmlns { get; set; }
[XmlAttribute(AttributeName="from")]
public string From { get; set; }
[XmlAttribute(AttributeName="stamp")]
public string Stamp { get; set; }
}
public class Active {
[XmlAttribute(AttributeName="xmlns")]
public string Xmlns { get; set; }
}
public class XmppMessage {
[XmlElement(ElementName="body")]
public string Body { get; set; }
[XmlAttribute(AttributeName="lang")]
public string Lang { get; set; }
[XmlAttribute(AttributeName="type")]
public string Type { get; set; }
[XmlAttribute(AttributeName="id")]
public string Id { get; set; }
[XmlAttribute(AttributeName="to")]
public string To { get; set; }
}
public class Forwarded {
[XmlElement(ElementName="delay")]
public Delay Delay { get; set; }
[XmlElement(ElementName="message")]
public XmppMessage Message { get; set; }
[XmlAttribute(AttributeName="xmlns")]
public string Xmlns { get; set; }
}
public class Result {
[XmlElement(ElementName="forwarded")]
public Forwarded Forwarded { get; set; }
[XmlAttribute(AttributeName="xmlns")]
public string Xmlns { get; set; }
[XmlAttribute(AttributeName="id")]
public string Id { get; set; }
}
[XmlRoot(ElementName="message")]
public class MessageHistory {
[XmlElement(ElementName="result")]
public Result Result { get; set; }
[XmlAttribute(AttributeName="from")]
public string From { get; set; }
[XmlAttribute(AttributeName="to")]
public string To { get; set; }
}
This is the code to deserialise:
MessageHistory messageNode;
XmlSerializer serializer = new XmlSerializer(typeof(MessageHistory));
using (StringReader reader = new StringReader(message))
{
messageNode = (MessageHistory)(serializer.Deserialize(reader));
}
The object property "from" and "to" are fine but the "Result" is returning null. I can't understand what I'm missing here...

The problem is the namespaces in the XML. you have to specify the namespaces explicitly, like this:
public class Forwarded
{
[XmlElement(ElementName = "delay", Namespace = "urn:xmpp:delay")]
public Delay Delay { get; set; }
[XmlElement(ElementName = "message")]
public XmppMessage Message { get; set; }
[XmlAttribute(AttributeName = "xmlns")]
public string Xmlns { get; set; }
}
public class Result
{
[XmlElement(ElementName = "forwarded", Namespace = "urn:xmpp:forward:0")]
public Forwarded Forwarded { get; set; }
[XmlAttribute(AttributeName = "xmlns")]
public string Xmlns { get; set; }
[XmlAttribute(AttributeName = "id")]
public string Id { get; set; }
}
[XmlRoot(ElementName = "message")]
public class MessageHistory
{
[XmlElement(ElementName = "result", Namespace = "urn:xmpp:mam:tmp")]
public Result Result { get; set; }
[XmlAttribute(AttributeName = "from")]
public string From { get; set; }
[XmlAttribute(AttributeName = "to")]
public string To { get; set; }
}

With this code when I click on Generate xml file, I got the error InvalidOperationException
There was an error reflecting type 'MergeExcelFiles.Orchard'.
{"There was an error reflecting property 'MyDatas'."}
Like you see in my comments, I try to just add a string xmlElement to node MyDatas, with this change I got no error but in the xml file I don't have any node with name Data.
I don't understand why with class Recipe all look right but with node MyDatas nothing showed in xml file or got this error "InvalidOperationException".

You need to dig into your error message more because the reason is in the innermost exception:
System.InvalidOperationException: Cannot serialize member 'Id' of type System.Nullable`1[System.Int32]. XmlAttribute/XmlText cannot be used to encode complex types.
The issue is that you have a nullable value type as a property (TrendDatas.Id) to be serialized as an attribute and XmlSerializer does not handle these well. There are a number of workarounds listed here and here. None of them is particularly elegant. The best option might be changing the definition of Id to an element:
public class TrendDatas
{
// ... snip ...
[XmlElement(IsNullable = true)]
public int? Id { get; set; }
public bool ShouldSerializeId() { return Id.HasValue; }
// ... snip ...
}
The ShouldSerializeId is a method that, by convention, the serializer uses to decide if the property should be serialized in the output. In the case of a null value, no element will be defined in the serialized output.
