Am having a class of this nature,

using Newtonsoft.Json;

namespace Models
{
    public class ItemsDbTable
    {
          [JsonProperty("City")]
          public string City { get; set; }
          [JsonProperty("Delivery.no")]
          public string DeliveryNo { get; set; }
          [JsonProperty("Delivery.type")]
          public string DeliveryType { get; set; }
          [JsonProperty("House.street.no")]
          public string HouseStreetNo { get; set; }
    }
}

Now the interesting part is when i have a List of ItemsDbTable and i start to iterate it. I want to get the values of the iterated instance of ItemsDbTable using the JsonPropertyAttribute.

Here is what i was doing,

Because my data came in via a web app, i Json-ised it but the fields are different than the ones i have for my Model. Thats why i used a JsonPropertyAttribute to aid in the mapping. But then am using another source of data which still refers to the old names that Json has to get the values.

Let me show you what am talking about.

 var itemsDbRow = str.ItemsDbTable.Single(x => 
     x.ArticlesKey == itemsTable.ArticlesKey);

So here i have an instance of itemsDbTable class.

Then i have a variable that is coming from somewhere, it however has the JsonPropertyAttributeName.

Then i search for the value like this

var val = itemsDbRow.GetType().GetProperties()
     .Select(propertyInfo => propertyInfo.GetCustomAttributesData()
     .Where(x => x.ConstructorArguments[0].Value.ToString() == bindingValueSrc));
