c# complex and large xml loading

c# complex and large xml loading - c#

I have some problems parsing huge xml in c#, mostly because I returned from apex to c# after a long time. So far I cant get working even this
private void read_Click(object sender, EventArgs e)
{
XElement xmlDoc = XElement.Load(#"D:\\AOI\\Samples\\Error\\60A84130868D_20180428035150_AOI-mek1.xml");
var loaded_File =
from fileInfo in xmlDoc.Descendants("result_file")
select new File
{
filename = fileInfo.Element("designator").Value,
supplier = fileInfo.Element("supplier").Value,
date_created = fileInfo.Element("date").Value,
station_ID = fileInfo.Element("station_ID").Value,
operator_ID = fileInfo.Element("operator_ID").Value,
program = fileInfo.Element("program").Value,
side_variant = fileInfo.Element("side_variant").Value
};
foreach(var item in loaded_File) {
System.Diagnostics.Debug.WriteLine(item.ToString());
}
}
Xml file looks as follows with multiple good_no and error_no, can someone navigate me how to load the file properly? I need it afterwards to insert it into database, but that should be just fine.
<result_file>
<filename>60Axxxxxek1</filename>

Thanks for advices.
EDIT:
I have also prepared classes for that
public class File
{
public string name { get; set; }
public string filename { get; set; }
public string supplier { get; set; }
public string date_created { get; set; }
public string station_ID { get; set; }
public string operator_ID { get; set; }
public string program { get; set; }
public string side_variant { get; set; }
public string pcbs_in_panel { get; set; }
public string serial { get; set; }
public string status { get; set; }
public string starttime { get; set; }
public string lot_no { get; set; }
public string window_no { get; set; }
public string packs_no { get; set; }
public string error_total { get; set; }
public string error_conf { get; set; }
public string inspection_time { get; set; }
public string panel_image { get; set; }
public string panel_image_location { get; set; }
public string ng_image_location { get; set; }
public string repaired { get; set; }
public List<Good> Goods = new List<Good>();
public List<Error> Errors = new List<Error>();
}
public class Good
{
public List<Good_no> Good_ones = new List<Good_no>();
}
public class Error
{
public List<Error_no> Error_ones = new List<Error_no>();
}
public class Good_no
{
public string name { get; set; }
public string designator { get; set; }
public string pin { get; set; }
public string stamp_name { get; set; }
public string package_name { get; set; }
public string pcb_no { get; set; }
public string feeder_no { get; set; }
public string pos_x { get; set; }
public string pos_y { get; set; }
public string window { get; set; }
public string comment { get; set; }
}
public class Error_no
{
public string name { get; set; }
public string designator { get; set; }
public string pin { get; set; }
public string stamp_name { get; set; }
public string package_name { get; set; }
public string errortype { get; set; }
public string error_contents { get; set; }
public string pcb_no { get; set; }
public string feeder_no { get; set; }
public string pos_x { get; set; }
public string pos_y { get; set; }
public string window { get; set; }
public string ng_message { get; set; }
public string comment { get; set; }
public string ng_image { get; set; }
}

You should simplify the class structure:
public class File
{
public string Filename { get; set; }
public string Supplier { get; set; }
// ...
public List<Good> Goods { get; set; }
public List<Error> Errors { get; set; }
}
public class Good
{
public string Name { get; set; }
public string Designator { get; set; }
public string Pin { get; set; }
// ...
}
public class Error
{
public string Name { get; set; }
public string Designator { get; set; }
// ...
}
Then the reading would look like this:
var xmlDoc = XElement.Load("test.xml");
var loadedFile = new File
{
Filename = xmlDoc.Element("filename").Value,
Supplier = xmlDoc.Element("supplier").Value,
// ...
Goods = (from good in xmlDoc.Element("goods").Elements("good_no")
select new Good
{
Name = good.Attribute("name").Value,
Designator = good.Element("designator").Value,
Pin = good.Element("pin").Value
// ...
})
.ToList()
};

If you want to read the XML-File, I recommmend you to deserialize the XML-files.
For this, your class-definition isn't complete. In Visual Studio is a tool, called xsd.exe. With this tool you can transform your XML-File first in a XSD-Schema. From the XSD-Schema you can generate the required classes.
To transform to XSD-Schema: xsd.exe {Filename.xml}
To transform to C#-Classes: xsd.exe /c {Filename.xsd}
XSD have many more options (see: https://msdn.microsoft.com/de-de/library/x6c1kb0s(v=vs.120).aspx)
If you have the correct classes you can read the XML-File with the XMLSerializer (see: https://msdn.microsoft.com/de-de/library/tz8csy73(v=vs.110).aspx)

Json string deserialization C#

I have this json
and i want to deserialize it so I can get each object's value for example:
"icon_url": "-9a81dlWLwJ2UUGcVs_nsVtzdOEdtWwKGZZLQHTxDZ7I56KU0Zwwo4NUX4oFJZEHLbXH5ApeO4YmlhxYQknCRvCo04DEVlxkKgpouLWzKjhzw8zFdC5K092kl5SClMj3PLXFhGpC_Pp8j-3I4IG7i1Hn_UI-Nmj3ItDGe1BoN1mCr1G4xL_vhMS8tcmcn3JhuihwsHvbzQv3309k3tBw8A",
The problem is I can make the class(es) that I need so I can deserialize the json because the json string has nested objects.

I used json2csharp to help me generate classes. After some merging and cleaning up, this is what I got:
public class InventoryItem
{
public string id { get; set; }
public string classid { get; set; }
public string instanceid { get; set; }
public string amount { get; set; }
public int pos { get; set; }
}
public class AppData
{
public string def_index { get; set; }
public int? is_itemset_name { get; set; }
public int? limited { get; set; }
}
public class Description
{
public string type { get; set; }
public string value { get; set; }
public string color { get; set; }
public AppData app_data { get; set; }
}
public class Action
{
public string name { get; set; }
public string link { get; set; }
}
public class Tag
{
public string internal_name { get; set; }
public string name { get; set; }
public string category { get; set; }
public string category_name { get; set; }
public string color { get; set; }
}
public class RgDescription
{
public string appid { get; set; }
public string classid { get; set; }
public string instanceid { get; set; }
public string icon_url { get; set; }
public string icon_url_large { get; set; }
public string icon_drag_url { get; set; }
public string name { get; set; }
public string market_hash_name { get; set; }
public string market_name { get; set; }
public string name_color { get; set; }
public string background_color { get; set; }
public string type { get; set; }
public int tradable { get; set; }
public int marketable { get; set; }
public int commodity { get; set; }
public string market_tradable_restriction { get; set; }
public List<Description> descriptions { get; set; }
public List<Action> actions { get; set; }
public List<Action> market_actions { get; set; }
public List<Tag> tags { get; set; }
}
public class RootObject
{
public bool success { get; set; }
public IDictionary<string, InventoryItem> rgInventory { get; set; }
public List<object> rgCurrency { get; set; }
public IDictionary<string, RgDescription> rgDescriptions { get; set; }
public bool more { get; set; }
public bool more_start { get; set; }
}
These appear to work correctly, you can deserialize and serialize with code like this:
var obj = JsonConvert.DeserializeObject<RootObject>(oldString);
Console.WriteLine(obj.rgDescriptions["310776560_302028390"].icon_url); // e.g.
var newString = JsonConvert.SerializeObject(obj,
new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
// null value handling is optional, the above makes it a little more like the source string

API returning a bunch of \t and \n

what am I doing wrong here? i'm trying to consume the ncaa data but I'm getting a bunch of \t and \n in my data, which makes it so I can't serialize it to an object. Here is my function, you can literally run this as it takes no credentials to get the data.
public string GetGameInfo(DateTime dt)
{
string content = string.Empty;
string url = "http://data.ncaa.com/jsonp/scoreboard/baseball/d1/2016/04/06/scoreboard.html";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.ContentType = "application/json";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();
using (StreamReader sr = new StreamReader(resStream))
{
content = sr.ReadToEnd();
}
return content;
}

}
protected void Page_Load(object sender, EventArgs e)
{
var json = GetGameInfo(DateTime.Now);
//this one doesn't work
//JsonConvert.DeserializeObject<Ncaa.callbackWrapper>(json);
//I tried removing the /ts and ns with no luck too
json = json.Replace("\t", string.Empty).Replace("\n", string.Empty);
JsonConvert.DeserializeObject<Ncaa.callbackWrapper>(json);
}

First of all, to answer why there's bunch of \ts and \ns in the response is because they ARE in your file. Those are respectively the tab character and the new line character.
I am not sure how you parse this , but most parsers should be able to handle this. In case you wrote your own, please post that code.
If the data returned will always be of format callback(JSON) you could strip the function call and simply parse the JSON using NewtonsoftJSON
EDIT: After reviewing the added code, I can notice that you are not stripping the function call. You should remove that and try again ( e.g. try removing everything until the first ocurrence of the { character and after last, or any other way you like )

Ok, so I did get it working. Doing this to the json helped.
json = json.Replace("callbackWrapper(", string.Empty).Replace(");", string.Empty);
Then, just parsing it as a scoreboard object, instead of a callback wrapper object.

Error in deserialize json in C#

here is my Get Set Method Class
public class RechargeGridDTO
{
public String from { get; set; }
public String to { get; set; }
public String errormsg { get; set; }
public String status { get; set; }
public RechargeInnerMsgGridInfo message { get; set; }
public String type { get; set; }
public String reqid { get; set; }
}
public class RechargeInnerMsgGridInfo

public String rcbal { get; set; }
public String rcsimbal { get; set; }
public String rcremark { get; set; }
public String rcchnnl { get; set; }
}
this is the json response I wanted to parse i-e:
msg = {
"from":"nishantuser",
"to":"smpp",
"errormsg":null,
"status":"s",
"message":
{
"mob":"9999999999",
"rctype":"Rr",

"rcmobile":"8460149820",
"rcamt":"20",
"rcpin":"1234",
"mytxid":"4850",
"optxid":GUJNishant123,
"txid":null,
"rcstatus":s,
"rcmsg":null,
"rctime":null,
"rcbal":null,
"rcsimbal":null,
"rcremark":null,
"rcchnnl":null
},
"type":"RECHARGE",
"reqid":"4850"
}
when i am parsing this json Response then getting error...
var ResponseData = JsonConvert.DeserializeObject<RechargeGridDTO>(msg);
please give me the solution how i can parse this type of Response in using JsonConvert in C#

"optxid":GUJNishant123,
"rcstatus":s,
Those parts are not valid JSON. Strings need to be quoted:
"optxid":"GUJNishant123",
"rcstatus":"s",

I need to parse json result in windows phone app c#

Im new in developing windows phone app --> i have problem so i have tried all the possible solutions but with no vain:-
the application tried to take result from webservice the result come back like this:-
{"d":"{\"sessionid\":null,\"VersionInfo\":{\"Rel\":0,\"Ver\":0,\"Patch\":0,\"ForceUpdate\":0,\"UpdateType\":0,\"Globals\":{\"MultiSessionsAllowed\":true,\"CommCalcType\":1,\"PriceChangedTimer\":20,\"ValidLotsLocation\":2,\"CustumizeTradeMsg\":true,\"FirstWhiteLabeledOffice\":null,\"DealerTreePriv\":0,\"ClientConnectTimer\":200,\"ClientTimeoutTimer\":500,\"DefaultLots\":0.01,\"WebSecurityID\":\"agagag\",\"ServerGMT\":3}},\"SystemLockInfo\":{\"MinutesRemaining\":0,\"HoursRemaining\":0,\"DaysRemaining\":0,\"Maintanance\":0,\"WillBeLocked\":1},\"FirstWhiteLabel\":\"HS Dev\",\"WLID\":\"3\",\"CheckWhiteLabel\":true,\"Password\":\"1234\",\"Username\":\"obeidat\",\"LastTickTime\":\"\/Date(1396613678728)\/\",\"SelectedAccount\":12345791,\"Name\":0,\"CompanyName\":\"HS Dev\",\"UserId\":579,\"DemoClient\":\"0\",\"FName\":\"obeidat\",\"SName\":null,\"TName\":null,\"LName\":null,\"Sms\":null,\"isReadOnly\":\"0\",\"SchSms\":\"0\",\"AlertSms\":\"0\",\"Temp\":null,\"GMTOffset\":\"5\",\"SvrGMT\":\"3\",\"ClientType\":null,\"EnableNews\":\"0\",\"PublicSlideNews\":\"\",\"PrivateSlideNews\":\"Thanks for using our platform##We will inform you here with any private news\",\"DealerTreePriv\":1}"}
so i have tried to parse it but it give me errors after that i have tried locally removed the {"d":" and \"LastTickTime\":\"\/Date(1396613678728)\/\" from the string with no connection to webservice and its working fine i use this code :-

Please help me to parse all of the json result (locally i mean without conection to web)and what is the code to do that.
thank you all

First, your JSON is all a string property of "D". You can't deserialize it to RootClass. Second, your JSON contains invalid escape characters in the LastTickTime area. I removed both of these, and the JSON parses without errors of any kind. I just used a console app to test it.
var s = "{\"sessionid\":null,\"VersionInfo\":{\"Rel\":0,\"Ver\":0,\"Patch\":0,\"ForceUpdate\":0,\"UpdateType\":0,\"Globals\":{\"MultiSessionsAllowed\":true,\"CommCalcType\":1,\"PriceChangedTimer\":20,\"ValidLotsLocation\":2,\"CustumizeTradeMsg\":true,\"FirstWhiteLabeledOffice\":null,\"DealerTreePriv\":0,\"ClientConnectTimer\":200,\"ClientTimeoutTimer\":500,\"DefaultLots\":0.01,\"WebSecurityID\":\"agagag\",\"ServerGMT\":3}},\"SystemLockInfo\":{\"MinutesRemaining\":0,\"HoursRemaining\":0,\"DaysRemaining\":0,\"Maintanance\":0,\"WillBeLocked\":1},\"FirstWhiteLabel\":\"HS Dev\",\"WLID\":\"3\",\"CheckWhiteLabel\":true,\"Password\":\"1234\",\"Username\":\"obeidat\",\"SelectedAccount\":12345791,\"Name\":0,\"CompanyName\":\"HS Dev\",\"UserId\":579,\"DemoClient\":\"0\",\"FName\":\"obeidat\",\"SName\":null,\"TName\":null,\"LName\":null,\"Sms\":null,\"isReadOnly\":\"0\",\"SchSms\":\"0\",\"AlertSms\":\"0\",\"Temp\":null,\"GMTOffset\":\"5\",\"SvrGMT\":\"3\",\"ClientType\":null,\"EnableNews\":\"0\",\"PublicSlideNews\":\"\",\"PrivateSlideNews\":\"Thanks for using our platform##We will inform you here with any private news\",\"DealerTreePriv\":1}";
var foo = JsonConvert.DeserializeObject<RootObject>(s);
Console.WriteLine(foo.UserId); // Writes 579
UPDATE
If you have no control over what you get back, do the following:
Take the response and get rid of the / combination. As such:
string webResponse = "your long web response from the server";
webResponse = webResponse.Replace(#"\/", "/");
// If dynamic isn't in the phone subset, you'll need a class here containing "d" as a string.
var jsonOuter = JsonConvert.DeserializeObject<dynamic>(webResponse);
var jsonInner = JsonConvert.DeserializeObject<RootObject>(jsonOuter.d);
if (jsonInner.UserId > .....)

The input is not a valid Base-64 when deserializing a json object

I got a json string from http://itunes.apple.com/lookup?id=796171602
this link always give me an array with only one Item. so instead of creating a class with root object and results array, I want to get the only first object and work with directly.
WebClient webClient = new WebClient();
webClient.Encoding = Encoding.UTF8;
string appJsonData = webClient.DownloadString("http://itunes.apple.com/lookup?id=796171602");
App app = new App();
JToken rootObject = JToken.Parse(appJsonData);
JToken appToken = rootObject["results"];
app = JsonConvert.DeserializeObject<App>(appJsonData);
when deserializing it, I get:
The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.
when I create a c# class using jsonpack.com it works.
my custom object is this:
public class App : Entity
{

doesn anyone have any idea?

this code works for your json string
var obj = JsonConvert.DeserializeObject<RootObject>(appJsonData);
public class Result
{
public string kind { get; set; }
public List<object> features { get; set; }
public List<string> supportedDevices { get; set; }
public bool isGameCenterEnabled { get; set; }
public List<string> screenshotUrls { get; set; }
public List<object> ipadScreenshotUrls { get; set; }
public string artworkUrl60 { get; set; }
public string artworkUrl512 { get; set; }
public string artistViewUrl { get; set; }
public int artistId { get; set; }
public string artistName { get; set; }
public double price { get; set; }
public string version { get; set; }
public string description { get; set; }
public string currency { get; set; }
public List<string> genres { get; set; }

public List<string> languageCodesISO2A { get; set; }
public string fileSizeBytes { get; set; }
public string contentAdvisoryRating { get; set; }
public double averageUserRatingForCurrentVersion { get; set; }
public int userRatingCountForCurrentVersion { get; set; }
public string artworkUrl100 { get; set; }
public string trackViewUrl { get; set; }
public string trackContentRating { get; set; }
}
public class RootObject
{
public int resultCount { get; set; }
public List<Result> results { get; set; }
}
EDIT
var obj = JsonConvert.DeserializeObject<JObject>(appJsonData)["results"][0] as JObject;
var app = obj.ToObject <Result>();
