Generate a flexible JSON array in VB.NET

Generate a flexible JSON array in VB.NET

Looking to generate a flexible array that can be converted into a JSON array for visualization with Morris charts. The usual approach in VB.NET is as follows:

 Dim xArray(2)

 xArray(0) = New With {Key .TradingDay = "Day1", .Seller1 = 1500, .Seller2 = 1600}
 xArray(1) = New With {Key .TradingDay = "Day2", .Seller1 = 2300, .Seller2 = 1850}
 xArray(2) = New With {Key .TradingDay = "Day3", .Seller1 = 4970, .Seller2 = 3560}

However, the challenge here lies in the dynamic nature of the Sellers involved. Clients should have the choice to select sellers from a listbox. In such cases, the setup could look like this:

 Dim xArray(2)

 xArray(0) = New With {Key .TradingDay = "Day1", .Seller2 = 1600, .Seller3 = 2550, .Seller4 = 3600}
 xArray(1) = New With {Key .TradingDay = "Day2", .Seller2 = 1850, .Seller3 = 890, .Seller4 = 3456}
 xArray(2) = New With {Key .TradingDay = "Day3", .Seller2 = 3560, .Seller3 = 10890, .Seller4 = 2850}

Is there a method to construct a dynamic array and convert it into a JSON format successfully?

To serialize an array using Newtonsoft.Json, you need to include the Import Newtonsoft.Json statement in your code. The example provided below demonstrates how you can modify and adapt it to suit your specific requirements.

 Public Class Product
      Public Property TradingDay As String
      Public Property sellers As List(Of Seller)
      End Class

      Public Class Seller
      Public Property SellerName As String
      Public Property price As String
      </Class>

     Dim mainList as List(of Product)

     ' Your main for loop

        Dim product As New Product()
        product.TradingDay = "Day1"
        dim sellerList as List(of Seller)
            ' Loop through sellers
                dim seller as new Seller()
                seller.SellerName ="name should be here"
                seller.price="your price"
                sellerList.add(seller)
            next
        product.sellers = sellerList
        mainList.add(product)
      Next
      Dim output As String = JavaScriptConvert.SerializeObject(mainList)
