Suppose this is my JSON data received through an API:
[
{
"id": "1",
"title": "Test_rom",
"subtitle": "",
"icon": "http://lpl.info/Admin/upload/cat.1.png"
},
{
"id": "2",
"title": "Jewelry",
"subtitle": "",
"icon": "http://lpl.info/Admin/upload/cat.2.png"
},
{
"id": "3",
"title": "Jackets",
"subtitle": "All sizes available",
"icon": "http://lpl.info/Admin/upload/cat.3.png"
}
]
I created a class called "RootObject":
public class RootObject {
public string id { get; set; }
public string title { get; set; }
public string subtitle { get; set; }
public string icon { get; set; }
}
I only want to extract values of "title" keys from the array. How can I achieve that?
I tried the following code, but I am getting error in "Encoding" word:
var result = await response.Content.ReadAsStringAsync();
RootObject TotalList = new RootObject();
RootObject childlistonly = new RootObject();
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(result));
DataContractJsonSerializer ser = new DataContractJsonSerializer(TotalList.GetType());
TotalList = ser.ReadObject(ms) as RootObject;
string category = "";
foreach(var d in TotalList.title) {
category = category + " " + d.ToString() + "\n";
}
ResultsText.Text = category;
I used the following, but it is giving an error:
var titlevariable = myobj.title;
Textblock.Text = titlevariable; // (under a click button method)...
Try this
foreach(var d in TotalList) {
category = category + " " + d.title.ToString() + "\n";
}

Question #1
In the switch case I want to fetch the value of com_cumulocity_model and id which belongs to the same JSON Object where case(value_of_description) is satisfied.
For example :
If case "Stop Station": is satisfied, I want to fetch the equivalent value of com_cumulocity_model and id inside it i.e. {"Mode": 0,"StopStationPayload": "[{\"ControllerAddress\":11,\"StationAddress\":26}]"} and "121985465" respectively. It must be compared to the value inside case and fetched on based of that.
Question #2
How do we add this value of id = "121985465" which we discussed above to the end of th url for making PostAsync request inside case("Stop Station") in lines var httpClientStopStation = httpClientFactory.CreateClient("executeOperations"); var request4 = await httpClientStopStation.PostAsync("");?
Short way. If you need just com_cumulocity_model
var operations = JObject.Parse(json)["operations"];
var com_cumulocity_model = operations.Where(o => (string) o["description"] == "Stop Station")
.Select(o => o["com_cumulocity_model"])
.FirstOrDefault();
Console.WriteLine(com_cumulocity_model.ToString());
result
{
"Mode": 0,
"StopStationPayload": "[{\"ControllerAddress\":11,\"StationAddress\":26}]"
}
But if you need the whole data you can use this code for deserializing json.
var data = JsonConvert.DeserializeObject<Data>(json);
classes
public class Data
{
public List<Operation> operations { get; set; }
public Statistics statistics { get; set; }
}
public class Operation
{
public DateTime creationTime { get; set; }
public string deviceId { get; set; }
public string deviceName { get; set; }
public string status { get; set; }
public ComCumulocityModel com_cumulocity_model { get; set; }
public string description { get; set; }
}
public class ComCumulocityModel
{
public string op { get; set; }
public string param { get; set; }
public string value { get; set; }
public int? Mode { get; set; }
public string StopStationPayload { get; set; }
}
public class Statistics
{
public int currentPage { get; set; }
public int pageSize { get; set; }
}
you can just remove Statistics class and statitics property from Data if you dont need it. The same about another properties
Now you can use Linq to get any data, for example
ComCumulocityModel com_cumulocity_model = data.operations
.Where(o => o.description == "Stop Station")
.Select(o => o.com_cumulocity_model)
.FirstOrDefault();
result (in json format)
{
"Mode": 0,
"StopStationPayload": "[{\"ControllerAddress\":11,\"StationAddress\":26}]"
}
how to print
var jsonSettings = new JsonSerializerSettings
{
NullValueHandling = NullValueHandling.Ignore,
Formatting=Newtonsoft.Json.Formatting.Indented
};
Console.WriteLine(JsonConvert.SerializeObject( com_cumulocity_model, jsonSettings));
Please check from Json output i wanted using JavaScriptSerializer. Then check class helper i created using json2csharp.com. Problem is in controller. I am not getting correct output as per my required Jason. I am doing correct in controller? Where the problem can be? Please ask question if you want to know something specific, sorry its hard to describe more clearly.
Helper Class Code:
public class ItemsFromFile
{
public string ASIN { get; set; }
public string Title { get; set; }
public List<Product> products { get; set; }
}
public class ItemsDeatails
{
public List<ItemsFromFile> ItemsFromFile { get; set; }
}
public class File
{
public string nameLocator { get; set; }
public ItemsDeatails itemsDeatails { get; set; }
}
public class RootObject
{
public string Token { get; set; }
public File file { get; set; }
}
Controller code:
if (type == "Salefreaks")
{
var token = ctx.BulkStores.FirstOrDefault(x => x.StoreName == store && x.Type == 1).Token;
var ItemsFromFile = new ItemsFromFile()
{
products = new List<Product>()
};
var ItemsDeatails = new ItemsDeatails()
{
};
var File = new File()
{
nameLocator = "testimport1"
};
var RootObject = new RootObject()
{
Token = token
};
var singleItems = ctx.BulkScannedItems.Where(x => x.UserSellerScanRequestId == id).ToList();
foreach (var item in singleItems)
{
ItemsFromFile.products.Add(new Product { ASIN = item.ASIN, Title = item.EbayTitle });
}
var json = new JavaScriptSerializer().Serialize(RootObject);
}
Required Json Output code:
{
"Token": "7f3099b0-36b1",
"file": {
"nameLocator": "testimport1",
"itemsDeatails": {
"ItemsFromFile": [
{
"ASIN": "B011KVFT9Y",
"Title": "Disney Batman Durable Party Beach Outdoor Adventure Camp Chair w/ Storage Bag"
},
{
"ASIN": "B01D4KRBW2",
"Title": "High Quality Diy Oil Painting Paint Number Kit Theme-Romantic Street A Frameless"
}
]
}
}
}
You can initialize internal objects in the code in the constructor as well.
public class RootObject
{
public string Token { get; set; }
public File file { get; set; }
}
public class File
{
public File()
{
this.itemsDeatails = new ItemsDeatails();
}
public string nameLocator { get; set; }
public ItemsDeatails itemsDeatails { get; set; }
}
public class ItemsDeatails
{
public ItemsDeatails(){
this.ItemsFromFile = new List<ItemsFromFile>();
}
public List<ItemsFromFile> ItemsFromFile { get; set; }
}
public class ItemsFromFile
{
public ItemsFromFile(){
this.products = new List<Product>();
}
public List<Product> products { get; set; }
}
public class Product {
public string ASIN { get; set; }
public string Title { get; set; }
}
Initialize your items properly. And create Root Object from the ground up.
Populate the internal classes first and then later ones.
var itemDetails = new ItemsDeatails();
itemDetails.ItemsFromFile = new ItemsFromFile();
var singleItems = ctx.BulkScannedItems.Where(x => x.UserSellerScanRequestId == id).ToList();
foreach (var item in singleItems)
{
itemDetails.ItemsFromFile.products.Add(new Product { ASIN = item.ASIN, Title = item.EbayTitle });
}
var fl = new File(){
nameLocator = "testimport1",
itemsDeatails = itemDetails
}
var token = ctx.BulkStores.FirstOrDefault(x => x.StoreName == store && x.Type == 1).Token;
var root = new RootObject()
{
Token = token,
file = fl
}
var json = new JavaScriptSerializer().Serialize(root);
Ensure that all your objects are assigned appropriately.
var token = ctx.BulkStores.FirstOrDefault(x => x.StoreName == store && x.Type == 1).Token;
var RootObject = new RootObject() {
Token = token,
file = new File() {
nameLocator = "testimport1",
itemsDeatails = new ItemsDeatails() {
ItemsFromFile = new List<ItemsFromFile>()
}
}
};
var itemsFromFile = new ItemsFromFile();
itemsFromFile.products = new List<Product>();
var singleItems = ctx.BulkScannedItems.Where(x => x.UserSellerScanRequestId == id).ToList();
foreach (var item in singleItems) {
itemsFromFile.products.Add(new Product { ASIN = item.ASIN, Title = item.EbayTitle });
}
RootObject.file.itemsDeatails.ItemsFromFile.Add(itemsFromFile);
var json = new JavaScriptSerializer().Serialize(RootObject);
That being said, it appears that you do not need the list of products inside of the ItemsFromFile class. This definition likely makes more sense:
public class ItemsFromFile {
public string ASIN { get; set; }
public string Title { get; set; }
}
Then your code would be something like this:
var token = ctx.BulkStores.FirstOrDefault(x => x.StoreName == store && x.Type == 1).Token;
var RootObject = new RootObject() {
Token = token,
file = new File() {
nameLocator = "testimport1",
itemsDeatails = new ItemsDeatails() {
ItemsFromFile = new List<ItemsFromFile>()
}
}
};
var singleItems = ctx.BulkScannedItems.Where(x => x.UserSellerScanRequestId == id).ToList();
foreach (var item in singleItems) {
RootObject.file.itemsDeatails.ItemsFromFile.Add(new ItemsFromFile { ASIN = item.ASIN, Title = item.EbayTitle });
}
This is my code in adding Fulfillment to Shopify orders but the converted json is not as expected.
Fullfillment product = new Fullfillment();
product.status = "success";
product.tracking_number = orderSent.TrackingNo;
List<LineItems> items = new List<LineItems>();
foreach (var item in orderSent.OrderLines)
{
LineItems line = new LineItems();
line.id = item.ProductName;
items.Add(line);
}
var json = JsonConvert.SerializeObject(product);
json = "{ \"fulfillment\": " + json + "}";
var json1 = JsonConvert.SerializeObject(items);
json = json + "{ \"line_items\": " + json1 + "}";
And this the converted json from this code:
{ "fulfillment": {
"id":0,
"status":"success",
"tracking_number":"xxxx12222",
}}{
"line_items": [
{
"id":"1234566645"
}
]
}
How can I turned like this:
{
"fulfillment": {
"tracking_number": null,
"line_items": [
{
"id": 466157049,
"quantity": 1
}
]
}
}
Model:
[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
public class Fullfillment
{
[JsonProperty(PropertyName = "id")]
public long id { get; set; }
[JsonProperty(PropertyName = "status")]
public string status { get; set; }
[JsonProperty(PropertyName = "tracking_number")]
public string tracking_number { get; set; }
}
[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
public class LineItems
{
[JsonProperty(PropertyName = "id")]
public string id { get; set; }
}
These are the models for Fulfillment and Line Items.
Thank you in advance for giving advices and help.
This works for me:
var json = JsonConvert.SerializeObject(new
{
fullfillment = new
{
product.tracking_number,
line_items = items.Select(x => new
{
x.id,
quantity = 1
})
}
});
That gives me:
{
"fullfillment" : {
"tracking_number" : "xxxx12222",
"line_items" : [{
"id" : "1234566645",
"quantity" : 1
}
]
}
}
I started with this code to build up the JSON above:
Fullfillment product = new Fullfillment();
product.status = "success";
product.tracking_number = "xxxx12222";
List<LineItems> items = new List<LineItems>();
LineItems line = new LineItems();
line.id = "1234566645";
items.Add(line);
Obviously you need to fill in your specific data.
Change your classes like below.
public class Rootobject
{
public Fulfillment fulfillment { get; set; }
}
public class Fulfillment
{
public string tracking_number { get; set; }
public Line_Items[] line_items { get; set; }
}
public class Line_Items
{
public string id { get; set; }
public int quantity { get; set; }
}
public class JsonTest
{
public void Test()
{
var root = new Rootobject();
root.fulfillment = new Fulfillment();
root.fulfillment.tracking_number = "xxxx12222";
root.fulfillment.line_items = new List<Line_Items>() { new Line_Items() { id = "1234566645", quantity = 1 } }.ToArray();
var json = JsonConvert.SerializeObject(root);
Console.WriteLine(json);
}
}
This will give you this json.
{
"fulfillment": {
"tracking_number": "xxxx12222",
"line_items": [
{
"id": "1234566645",
"quantity": 1
}
]
}
}
Try the following
public class Rootobject
{
public Fulfillment fulfillment { get; set; }
}
public class Fulfillment
{
public string tracking_number { get; set; }
public Line_Items[] line_items { get; set; }
}
public class Line_Items
{
public string id { get; set; }
public int quantity { get; set; }
}
public class JsonTest
{
public void Test()
{
var root = new Rootobject();
root.fulfillment = new Fulfillment();
root.fulfillment.tracking_number = "xxxx12222";
root.fulfillment.line_items = new List<Line_Items>() { new Line_Items() { id = "1234566645", quantity = 1 } }.ToArray();
var json = JsonConvert.SerializeObject(root);
Console.WriteLine(json);
}
}

doc.Parts.Add(new DocPart { Title = "bbb", TexLine = #"\include{bbb.tex}" });
this.Parts = new List<DocPart>();
foreach (DocPart part in doc.Parts)

Console.ReadLine();
}
}

var ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonData));
var config = (DocConfig)serializer.ReadObject(ms);

Can't you just use linq string.Join(",", my list)?

This code looks bad if the json data changes then you need to modify your logic accordingly. I would suggest you to serialize and deserialize the model data using Json serialization.
Model:
public class SerializationModel
{
public Data Data { get; set; }
}
public class Data
{
public string Name { get; set; }
public string Gender { get; set; }
public string Id { get; set; }
public Picture Picture { get; set; }
}
public class Picture
{
public PictureData Data { get; set; }
}
public class PictureData
{
public bool is_silhouette { get; set; }
public string url { get; set; }
}
Serialize your data to get the json output is like,
SerializationModel serializationModel = new SerializationModel
{
Data = new Data
{
Gender = "mALE",
Id = "88",
Name = "User",
Picture = new Picture
{
Data = new PictureData
{
is_silhouette = true,
url = "www.google.com"
}
}
}
};
string serializedString = Newtonsoft.Json.JsonConvert.SerializeObject(serializationModel);
which would yield the below result,
{"Data":{"Name":"User","Gender":"mALE","Id":"88","Picture":{"Data":{"is_silhouette":true,"url":"www.google.com"}}}}
To deserialize the json data back to the model,
SerializationModel sm = Newtonsoft.Json.JsonConvert.DeserializeObject<SerializationModel>(serializedString);
Then you can get the required values from the model itself.
