Połączenie API do sklepu RedCart C# (vb.net)

Dzień dobry

Pomógłby mi ktoś w przepisaniu poniższego kodu w Phytonie na C# VB.net ? Oczywiście może być z wykorzystaniem newtonsoft json
Próbowałam już na wiele sposobów i cały czas mi zwraca komunikat o błędnym json
Za pomocą Postmana dostaję prawidłową odpowiedź

Kod w Phytonie:

import urllib
import urllib2
import simplejson as json
data = {
 'key' : 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
 'viewType' : 'json',
 'module' : 'hello',
 'method' : 'hello',
 'parameters' : {'name': 'redcart'}
}
jsonData = {'json' : json.dumps(data)}
postData = urllib.urlencode(jsonData)
req = urllib2.Request("http://api2.redcart.pl/?input=json",postData)
opener = urllib2.build_opener()
f = opener.open(req)
result = json.load(f) 
print(result)

parameters (array)
tablica parametrów (pól) bazy danych
np. array('products_id' => 100, 'products_name' => 'Pralka J23')

czyli musisz zrobić tablicę, a nie obiekt dla parametrów

czyli np

paramters[
{"key1":"value1"},
{"key2":"value2"}
]

W Pythonie (przerobiłam trochę to co jest w dokumentacji a ja zamieściłam na początku wątku) piszę tak :

import urllib
import urllib.parse
import urllib.request
import json 
from json import JSONEncoder

class Parameters:
    def __init__(self, name):
        self.name = name

class Sayhelo:
    def __init__(self, key, viewType, module, method, parameters):
            self.key=key
            self.viewType=viewType
            self.module=module
            self.method=method
            self.parameters=parameters

    
# subclass JSONEncoder
class encoder(JSONEncoder):
        def default(self, o):
            return o.__dict__


parameters=Parameters("RED CART")
sayhelo=Sayhelo("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx","json","hello","hello",parameters)       
jsonData = {"json" : json.dumps(sayhelo,indent=None, cls=encoder)}
print()
print(jsonData)
postData = urllib.parse.urlencode(jsonData)
data = postData.encode('utf-8')
print()
print(data)
req = urllib.request.Request("http://api2.redcart.pl/?input=json", data=data)
r = urllib.request.urlopen(req)
content = r.read().decode()
print()
print(content) 

request wygląda następująco:

{'json': '{"key": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "viewType": "json", "module": "hello", "method": "hello", "parameters": {"name": "RED CART"}}'}

i odpowiedź jest prawidłowa, więc to raczej nie o parametry chodzi
