Convert JSON String to JSON Object C#

Convert JSON String to JSON Object c#

JObject defines method Parse for this:

JObject json = JObject.Parse(str);

You might want to refer to Json.NET documentation.

Converting a string to JSON in C#

First, create your data model. You can use json2sharp, very helpful tool.

public class Item
{
    public int id { get; set; }
    public string title { get; set; }
    public int position_x { get; set; }
    public int position_y { get; set; }
    public int position_z { get; set; }
    public int rotation_x { get; set; }
    public int rotation_y { get; set; }
    public int rotation_z { get; set; }
    public string created { get; set; }
}

Next use Newtonsoft.Json and call deserialize method.

var list = JsonConvert.DeserializeObject<List<Item>>(Yourjson);

In C# convert Json string to Json Object

You can remodel your POCO:

public class ProductEntity
{
    [JsonProperty("products")]
    public List<Product> Products { get; set; }
}

public class Product
{
    [JsonProperty("id")]
    public string Id { get; set; }

    [JsonProperty("name")]
    public string Name { get; set; }

    [JsonProperty("price")]
    public string PricePerUnit { get; set; }
}

And then de-serialize it as follows:

internal class Solution1
{
    static void Main(string[] args)
    {
        string str = @"
        {
             'products': [
               {
                'id': '1',
                'name': 'red apple',
                'price': '1.53'
               },
               {
                 'id': '2',
                 'name': 'green walnut',
                 'price': '0.25'
               },
               {
                 'id': '3',
                 'name': 'avocado',
                 'price': '0.33'
               }
             ]
          }";

        ProductEntity result = JsonConvert.DeserializeObject<ProductEntity>(str);
    }
}

Convert string to json using C#

You can do something like this:

var jobject = JsonConvert.DeserializeObject<JObject>(yourVariable);

this is using Newtonsoft's json library that you can get from nuget.

Also JObject is the C# equivalent to a JSON object so that's probably something you'll want to use.

How to convert an embedded JSON string to a JSON Object in C#

If you know the json response, you can create a model class for it. On VS 2022 you can right click on editor and do paste special Edit --> Paste special --> Paste JSON as Classes. You should get something like below.

public class Model 
{
    public object[] paymentId { get; set; }
    public object[] paymentRequestId { get; set; }
    public object[][][] paymentAmount { get; set; }
    public object[] paymentStatus { get; set; }
    public object[][][] result { get; set; }
}

After using that Model class in your code, your code should look like below

using System.Text.Json;

public Model InquiryPaymentAPI(string id)
{
   
    string paymentInfo = PaymentInquiry.IPayment(id);
    return JsonSerializer.Deserialize<Model>(paymentInfo);

}

Convert JSON String To C# Object

It looks like you're trying to deserialize to a raw object. You could create a Class that represents the object that you're converting to. This would be most useful in cases where you're dealing with larger objects or JSON Strings.

For instance:

  class Test {

      String test; 

      String getTest() { return test; }
      void setTest(String test) { this.test = test; }

  }

Then your deserialization code would be:

   JavaScriptSerializer json_serializer = new JavaScriptSerializer();
   Test routes_list = 
          (Test)json_serializer.DeserializeObject("{ \"test\":\"some data\" }");

Parse JSON String to JSON Object in C#.NET

use new JavaScriptSerializer().Deserialize<object>(jsonString)

You need System.Web.Extensions dll and import the following namespace.

Namespace: System.Web.Script.Serialization

How to convert json format string to json in c#

This is an invalid JSON format, moreover it does not have surrounding array brackets []. Ideally you should fix this at source.

You could do a simple replace

MyLabels = JsonConvert.DeserializeObject<List<Label>>(labelnames = "[" + labelnames.Replace("'", "\"") + "]")

However this may throw an error if any of the values also contain a '.

Therefore, you could create a custom JsonTextReader

        using (var sw = new StringReader("[" + labelnames + "]"))
        using (var reader = new MyJsonTextReader(sw))
        {
            JsonSerializer ser = new JsonSerializer();
            MyLabels = ser.Deserialize<List<Label>>(reader);
        }

    class MyJsonTextReader : JsonTextReader
    {
        public override char QuoteChar { get; protected set; } = '\'';
        
        public MyJsonTextReader(TextReader r) : base(r){}
    }
    class Label
    {
        public string LabelName;
        public bool IsHeader;
    }
