problems reading a json already converted to object - vb.net

Question

I have the following json
{"24":[ { "data": "13", "moment": "07/20/2018" },{ "data": "16", "moment": "07/20/2018 0:15 :00" }]}
How would it be to go through it once read and converted to a json object using vbnet. I mean how to go through it
Update:
Dim request As WebRequest = WebRequest.Create(url_Final)
request.Method = "POST"
Dim Response As WebResponse = request.GetResponse()
Dim datastream = Response.GetResponseStream()
Dim reader As New StreamReader(datastream)
Dim responsefromServer = reader.ReadToEnd()
If responsefromServer = "0" Then
Console.Write("Fail json")
Else
Console.WriteLine(responsefromServer)
Dim result = JsonConvert.DeserializeObject(Of resultApi)(responsefromServer)
For Each magnitud In result
Console.WriteLine(magnitud)
Next
Console.ReadKey()
reader.Close()
Response.Close()
End If
Catch ex As Exception
Console.WriteLine(ex)
End Try
Update
Public Class resultApi
Public Property Magnitud As String
Public Property Sentilo As List(Of SentiloClass)
End Class
Public Class SentiloClass
Public Property data As Integer
Public Property moment As DateTime
End Class
Adding some classes created

Agree with Jimi's comment, if you've got varying key names that are carrying data that is important to you it's often easiest to just deser them to a dictionary so you can skip through it afterwards
Presumably you wanted a list of resultApi out of this
dim result = JsonConvert.DeserializeObject(Of Dictionary(Of String, List(Of SentiloClass)))(responsefromServer)
dim resultApis = result.Select( _
Function(kvp) _
New resultApi With {.Magnitud = kvp.Key, .Sentilo = kvp.Value} _
)
