You can convert JSON to C# model using quicktype :
namespace QuickType
{
using System;
using System.Collections.Generic;
using System.Globalization;
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
public partial class Product
{
[JsonProperty("Category")]
public string Category { get; set; }
[JsonProperty("DateB")]
public string DateB { get; set; }
[JsonProperty("Description")]
public string Description { get; set; }
[JsonProperty("ProductName")]
public string ProductName { get; set; }
[JsonProperty("Price")]
public long Price { get; set; }
[JsonProperty("ProductD")]
public bool ProductD { get; set; }
[JsonProperty("id")]
public long Id { get; set; }
}
public partial class Product
{
public static Dictionary<string, Product> FromJson(string json) => JsonConvert.DeserializeObject<Dictionary<string, Product>>(json, QuickType.Converter.Settings);
}
public static class Serialize
{
public static string ToJson(this Dictionary<string, Product> self) => JsonConvert.SerializeObject(self, QuickType.Converter.Settings);
}
internal static class Converter
{
public static readonly JsonSerializerSettings Settings = new JsonSerializerSettings
{
MetadataPropertyHandling = MetadataPropertyHandling.Ignore,
DateParseHandling = DateParseHandling.None,
Converters =
{
new IsoDateTimeConverter { DateTimeStyles = DateTimeStyles.AssumeUniversal }
},
};
}
}
And after create ListView with ViewCell and ViewModel. In this case, ViewModel will include properties from the product model.
