Can not deserialize Xml getting from api

Can not deserialize Xml getting from api - c#

I am using World Weather Online API to get the weathers of specific location. My problem is while I am trying to deserialize XML output coming from API Response stream, I am getting error with: There is a problem with XML document (1,1).
Uri apiURL = new Uri(#"http://api.worldweatheronline.com/free/v1/weather.ashx?q=Dhaka&format=xml&num_of_days=1&date=today&key=jzb88bpzb5yvaegukmq97mee");
Stream result = RequestHandler.Process(apiURL.ToString());
XmlSerializer des = new XmlSerializer(typeof(LocalWeather));
StreamReader tr = new StreamReader(result);
Object obj = des.Deserialize(tr);
LocalWeather data = (LocalWeather)obj;
Sample XML file from Web API:

You need to update the class to match the schema of the XML structure (these are case sensitive).
You can start with your existing file using the attributes found in System.Xml.Serialization.
[XmlRoot("data")]
public class Data {
// and so on..
}
Or you could use the XSD tool to generate the class for you following these steps.
Create schema for the XML returns from the service (Xml -> Create Schema)
In VS Studio tools run this command: XSD XmlSchema.xsd /c (where XmlSchema.xsd is the schema produced in step 1).

The way that your model is set up right now, you have LocalWeather as the root, whereas in the actual XML the root is Data. That's why you're getting the "Invalid root node" error. So, instead of
XmlSerializer des = new XmlSerializer(typeof(LocalWeather));
StreamReader tr = new StreamReader(result);
Object obj = des.Deserialize(tr);
LocalWeather data = (LocalWeather)obj;
try
XmlSerializer des = new XmlSerializer(typeof(Data));
StreamReader tr = new StreamReader(result);
Object obj = des.Deserialize(tr);
Data data = (Data)obj;

Retrieve XML column from DataBase with lines C#

I run query against DB which returns me 1 row 2 columns. Each column has XML(script) inside which I need to retrieve into (ideally string) and then execute against DB.
I need the retrieved string to have lines and formatting as if i would copy if from SQL management studio.
Part of XMLresult from SQL management studio I need this format. replacement: XXXXXX

Thanks for any advice.

So the key is to get the proper indentation?
In that case, I would recommend taking a look at the following SO thread:
Format XML string to print friendly XML string
The key is that you need indentation, which can be achieved through the XmlTextWrite.Formatting = Formatting.Indented option.

Use XML serializer. See code below

const string OUTPUT_FILENAME = #"c:\temp\test1.xml";
static void Main(string[] args)
{
string xml = File.ReadAllText(INPUT_FILENAME);
StringReader sReader = new StringReader(xml);
XmlReader reader = XmlReader.Create(sReader);
XmlSerializer serializer = new XmlSerializer(typeof(Message));
Message message = (Message)serializer.Deserialize(reader);
//write
XmlSerializerNamespaces names = new XmlSerializerNamespaces();
names.Add("q1", "XXXXXX");
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
MemoryStream stream = new MemoryStream();
XmlWriter writer = XmlWriter.Create(stream);
serializer.Serialize(writer,message,names);
byte[] buffer = new byte[stream.Length];
stream.Position = 0;
stream.Read(buffer, 0, (int)stream.Length);
string output = Encoding.UTF8.GetString(buffer);
}

Xml deserialization returns empty array even though POCO has right xml attributes generated from xsd2code++ tool

I am using XSD2Code++ 2019 tool for visual studio to generate POCOs from aset of 5 xsds. I have added the POCO class below. I see that it has the right xml decorators for it to serialize properly. But I really fail to understand or figure out why the 3rd level object in the returned deserialized data is always empty and not typecasted to the correct type.
I have tried changing attributes to xmlArray and xmlArrayElement too but none of that worked.
POCO class-

Code to deserialize-
string responseText = apiResponse.ReadToEnd();
var responseSerializer = new XmlObjectSerializer();
IntuitResponse restResponse =
(IntuitResponse)this.responseSerializer.Deserialize<IntuitResponse>(responseText);
res=restResponse.Items[0] as QueryResponse;
here QueryResponse is not having Invoice(of type IntuitEntity) object returned. Instead empty value is returned. See screenshot.

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

Following is the Class
[XmlType("TRANSACTION_RESPONSE")]
public class BankQueryResponse
{
[XmlElement("TRANSACTION_ID")]
public string TransactionId { get; set; }
[XmlElement("MERCHANT_ACC_NO")]
public string MerchantAccNo { get; set; }
[XmlElement("TXN_SIGNATURE")]
public string TxnSignature { get; set; }
[XmlElement("TRAN_DATE")]
public DateTime TranDate { get; set; }
[XmlElement("TXN_STATUS")]
public string TxnStatus { get; set; }
[XmlElement("REFUND_DATE")]
public DateTime RefundDate { get; set; }
[XmlElement("RESPONSE_CODE")]
public string ResponseCode { get; set; }
[XmlElement("RESPONSE_DESC")]
public string ResponseDesc { get; set; }
[XmlAttribute("MERCHANT_TRANID")]
public string MerchantTranId { get; set; }
}
The deserialization code is
BankQueryResponse result = new BankQueryResponse();
if(!string.IsNullOrEmpty(responseData))
{
XmlSerializer serializer = new XmlSerializer(typeof(BankQueryResponse));
using(TextReader xmlreader = new StringReader(responseData))
{
result = (BankQueryResponse) serializer.Deserialize(xmlreader);
}
}
I am getting all value in result as null . I am not sure whats the reason . Can some one throws a light into the issue. Am i missing something while deserialising

You should modify the code something like this
[XmlType("TRANSACTION_RESPONSE")]
public class TransactionResponse
{
[XmlElement("TRANSACTION")]
public BankQueryResponse Response { get; set; }
}
This will change like this
public class BankQueryResponse
{
[XmlElement("TRANSACTION_ID")]
public string TransactionId { get; set; }
[XmlElement("MERCHANT_ACC_NO")]
public string MerchantAccNo { get; set; }
[XmlElement("TXN_SIGNATURE")]
public string TxnSignature { get; set; }
[XmlElement("TRAN_DATE")]
public DateTime TranDate { get; set; }
[XmlElement("TXN_STATUS")]
public string TxnStatus { get; set; }
[XmlElement("REFUND_DATE")]
public DateTime RefundDate { get; set; }
[XmlElement("RESPONSE_CODE")]
public string ResponseCode { get; set; }
[XmlElement("RESPONSE_DESC")]
public string ResponseDesc { get; set; }
[XmlAttribute("MERCHANT_TRANID")]
public string MerchantTranId { get; set; }
}
Deseralization Code would be something like this
TransactionResponse result = new TransactionResponse();
if(!string.IsNullOrEmpty(responseData))
{
XmlSerializer serializer = new XmlSerializer(typeof(TransactionResponse));
using(TextReader xmlreader = new StringReader(responseData))
{
result = (TransactionResponse) serializer.Deserialize(xmlreader);
}
}

How do I deserialise this JSON?

I haven't done anything with JSON before... so I am probably just missing a step.
Here is an example of the JSON I want to deserialise:
{"item":{"icon":"http://services.runescape.com/m=itemdb_rs/4765_obj_sprite.gif?id=4798","icon_large":"http://services.runescape.com/m=itemdb_rs/4765_obj_big.gif?id=4798","id":4798,"type":"Ammo","typeIcon":"http://www.runescape.com/img/categories/Ammo","name":"Adamant brutal","description":"Blunt adamantite arrow...ouch","current":{"trend":"neutral","price":237},"today":{"trend":"neutral","price":0},"members":"true","day30":{"trend":"positive","change":"+1.0%"},"day90":{"trend":"negative","change":"-0.0%"},"day180":{"trend":"positive","change":"+0.0%"}}}
I put this into "Json 2 C#" and ended up creating this new .cs file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace RSTool.Models
{
public class Current
{
public string trend { get; set; }
public int price { get; set; }
}
public class Today
{
public string trend { get; set; }
public int price { get; set; }
}
public class Day30
{
public string trend { get; set; }
public string change { get; set; }
}
public class Day90
{
public string trend { get; set; }
public string change { get; set; }
}
public class Day180
{
public string trend { get; set; }
public string change { get; set; }
}
public class Item
{
public string icon { get; set; }
public string icon_large { get; set; }
public int id { get; set; }
public string type { get; set; }
public string typeIcon { get; set; }
public string name { get; set; }
public string description { get; set; }
public Current current { get; set; }
public Today today { get; set; }
public string members { get; set; }
public Day30 day30 { get; set; }
public Day90 day90 { get; set; }
public Day180 day180 { get; set; }
}
public class RootObject
{
public Item item { get; set; }
}
}
So, I have the class. I can retrieve the JSON from its location as a string, but I really have no idea how to deserialise it... I have installed Newtonsoft.Json and have tried using PopulateObject and also Deserializer but not with any luck...
Assuming that my JSON is stored as a string called "json", how would I go about storing that query and then retrieving the item name, for example?

Use:
var deserialized = JsonConvert.DeserializeObject<RootObject>(json);
I just tested this successfully given the code you supplied.
You can then access properties of object as normal:
MessageBox.Show(deserialized.item.name);
