Loop through large nested JSON string using C# or VB into datatable

Question

I have a large nested JSON string that (parent/child). I need to be able to loop through it following the nesting. I have tried various references regarindg newtonsoft but I can't get it to work. I'm sure it must be simple but I can't work it out.

I have created the following object:-

Public Class MenuObject

    Public Property data_tagname As String
    Public Property data_title As String
    Public Property data_menuid As String
    Public Property data_parentid As String
    Public Property data_cmsid As String
    Public Property data_enabled As String
    Public Property data_isparent As String
    Public Property subLevel As List(Of Object)

End Class

And when I try using the following:-

Dim data = JsonConvert.DeserializeObject(Of MenuObject)(strJson)

I get the following error:-

Message=Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'MenuObject' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.

Here is the JSON:-

Answer 1

There is a page called https://quicktype.io/ where you can paste your JSON and get your c# classes generated.

Afterwards you should be able to parse your JSON into c# objects and enumerate your objects like:

class Program
{
    static void Main()
    {
        // read the JSON into variable
        string json = System.IO.File.ReadAllText("input.json");

        // Convert the JSON text into C# object
        var welcomes = Welcome.FromJson(json);
        foreach (var welcome in welcomes)
        {
            // Your logic
        }
    }
}
