How can i convert php AES encryption code to c#

Question

I'm creating an C# MVC application by calling Api, Its token encryption method is in PHP i want to convert it to C# code.Can any one help in conversion on below php code to c#?

PHP Code

<?php
//ini_set("display_errors", 1);
//ini_set("display_startup_errors", 1);
function encryptToken($token)
{  
    $cipher_method = 'aes-128-ctr';  
    $enc_key = openssl_digest

('*****************************', 'SHA256', TRUE);  
    $enc_iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length($cipher_method)); 
     $crypted_token = openssl_encrypt($token, $cipher_method, $enc_key, 0, $enc_iv) . "::" . bin2hex($enc_iv); 
      unset($token, $cipher_method, $enc_key, $enc_iv);  
      return $crypted_token; 
    }  
function createAccessToken(){ 
  //$date = new DateTime("now", new DateTimeZone('Asia/Kolkata') );  
 //$now = $date('YmdHis'); 
 $now = date("YmdHis");
 $secret ='********************************';  
 $plainText = $now."::".$secret;  
 $encrypted = encryptToken($plainText);  
 return $encrypted; 
} 

$value="";
if($_POST){
    if(isset($_POST['test'])){

         $value= createAccessToken();
    }
}
?>

So far i tried this much. But the token generated using this C# code will not validate in Api by using the same secret and password.

C# Code

   public string GenerateToken()
        {
            var Date = DateTime.Now.ToString("yyyyMMddHHmmss");
            var secret = "#############################";
            string plainText = Date + "::" + secret;
            var accessToken = EncryptString(plainText);
            return accessToken;
        }


public string EncryptString(string plainText)
    {
        try
        {
            string password = "************************";
            // Create sha256 hash
            SHA256 mySHA256 = SHA256Managed.Create();
            byte[] key = mySHA256.ComputeHash(Encoding.ASCII.GetBytes(password));
            // Instantiate a new Aes object to perform string symmetric encryption
            Aes encryptor = Aes.Create();
            encryptor.Mode = CipherMode.ECB;
            encryptor.Padding = PaddingMode.None;
            encryptor.BlockSize = 128;
            // Create secret IV
            var iv = generateIV();
            // Set key and IV
            byte[] aesKey = new byte[32];
            Array.Copy(key, 0, aesKey, 0, 32);
            encryptor.Key = aesKey;
            encryptor.IV = iv;

            // Instantiate a new MemoryStream object to contain the encrypted bytes
            MemoryStream memoryStream = new MemoryStream();

            // Instantiate a new encryptor from our Aes object
            ICryptoTransform aesEncryptor = encryptor.CreateEncryptor();

            // Instantiate a new CryptoStream object to process the data and write it to the 
            // memory stream
            CryptoStream cryptoStream = new CryptoStream(memoryStream, aesEncryptor, CryptoStreamMode.Write);

            // Convert the plainText string into a byte array
            byte[] plainBytes = Encoding.ASCII.GetBytes(plainText);

            // Encrypt the input plaintext string
            cryptoStream.Write(plainBytes, 0, plainBytes.Length);

            // Complete the encryption process
            cryptoStream.FlushFinalBlock();

            // Convert the encrypted data from a MemoryStream to a byte array
            byte[] cipherBytes = memoryStream.ToArray();

            // Close both the MemoryStream and the CryptoStream
            memoryStream.Close();
            cryptoStream.Close();

            // Convert the encrypted byte array to a base64 encoded string
            string cipherText = Convert.ToBase64String(cipherBytes, 0, cipherBytes.Length) + "::" + ByteArrayToString(iv);

            // Return the encrypted data as a string
            return cipherText;
        }
        catch (Exception)
        {

            throw;
        }
    }
    private static byte[] generateIV()
    {
        using (RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider())
        {
            byte[] nonce = new byte[IV_LENGTH];
            rng.GetBytes(nonce);
            return nonce;
        }
    }
