Encrypted in C# and decrypted in PHP

Hi all,

I am working on the php program to decrypted the password which is encrypted by C#. However, the codes show below could not work. Any ideas?

C# coding:
private static String password = @abc;
private static String saltV = @123;
private static String hashAlgorithm = "SHA1";
private static int passwordIterations = 2;
private static String iv = @123456789123456;
private static int keySize = 256;

public static string Encrypt(string text)
byte[] ivBytes = Encoding.ASCII.GetBytes(iv);
byte[] saltBytes = Encoding.ASCII.GetBytes(saltV);
byte[] textBytes = Encoding.UTF8.GetBytes(text);

PasswordDeriveBytes key = new PasswordDeriveBytes(
password, saltBytes, hashAlgorithm, passwordIterations);

byte[] keyBytes = key.GetBytes(keySize / 8);

RijndaelManaged symmetricKey = new RijndaelManaged();
symmetricKey.Mode = CipherMode.CBC;

ICryptoTransform encryptor =symmetricKey.CreateEncryptorkeyBytes, ivBytes);

MemoryStream memoryStream = new MemoryStream();
CryptoStream cryptoStream = new CryptoStream(memoryStream, cryptor, CryptoStreamMode.Write);
cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length);

byte[] cipherTextBytes = memoryStream.ToArray();
return Convert.ToBase64String(cipherTextBytes);

************************************************** **********************************
PHP coding:
function decrypt($crytedText) {
$key = "abc";
$iv = "123456789123456";
$text = mcrypt_decrypt(MCRYPT_RIJNDAEL_256,$key,$cryptedTe xt, MCRYPT_MODE_CBC, $iv);
