.NET Equivalents to Java Crypto stuff

Could anybody tell me what the equivalent .N开发者_如何学CET classes/methods are to the following Java methods:

decryptCipher = Cipher.getInstance("DES/ECB/PKCS5Padding");
decryptCipher.init(2, getKey(0));
decryptCipher.doFinal(data);

where getKey() returns an object of type SecretKeySpec (data is dummy):

public static Key getKey(int cipher) {
    if (cipher == 0) {
      return new SecretKeySpec(new byte[] { 1, 1, 1, 1, 1, 1, 1, 1 }, "DES");
    }
    return new SecretKeySpec(new byte[] { 2, 2, 2, 2, 2, 2, 2, 2 }, "DES");
  }

Many thanks

Tony
