decode encoded string code example

Example 1: JavaScriptSerializer() and convert to base64

class Program
{
    static void Main(string[] args)
    {
        var account = new ExternalAccount() { Name = "Someone" };
        string json = JsonConvert.SerializeObject(account);
        string base64EncodedExternalAccount = Convert.ToBase64String(Encoding.UTF8.GetBytes(json));
        byte[] byteArray = Convert.FromBase64String(base64EncodedExternalAccount);

        string jsonBack = Encoding.UTF8.GetString(byteArray);
        var accountBack = JsonConvert.DeserializeObject<ExternalAccount>(jsonBack);
        Console.WriteLine(accountBack.Name);
        Console.ReadLine();
    }
}

[Serializable]
public class ExternalAccount
{
    public string Name { get; set; }
}

Example 2: decoding encoding script for pythong

#novince coder, dont know if im doing this right XD
EncodingValues = ['q','w','e','r','t','y','u','i','o','p','a','s','d','f','g','h','j','k','l','z','x','c','v','b','n','m','Q','W','E','R','T','Y','U','I','O','P','A','S','D','F','G','H','J','K','L','Z','X','C','V','B',',','N','M','!','@','$','%','^','&','*','(',')','_','+','-','=','#']
encode = "this"

def encode(string):
  encodedcode = ""
  LetterToEncode = 0
  for i in string:
    LetterToEncode = LetterToEncode + 1
    encodedcode = encodedcode + EncodingValues.index(LetterToEncode)
    encodedcode = encodedcode + " "
    #still editing this
  
def decode(string):
  decodedcode = ""
  LetterToDecode = 0
  for i in string:
    LetterToDecode = LetterTodecode + 1
    if string.index(letterToDecode + 2) = " "
    decodedcode = decodedcode + EncodingValues.index(LetterToDecode)
