任何人都可以告诉我如何从以下代码中删除所有CA2202警告？

public static byte[] Encrypt(string data, byte[] key, byte[] iv)
{
    using(MemoryStream memoryStream = new MemoryStream())
    {
        using (DESCryptoServiceProvider cryptograph = new DESCryptoServiceProvider())
        {
            using (CryptoStream cryptoStream = new CryptoStream(memoryStream, cryptograph.CreateEncryptor(key, iv), CryptoStreamMode.Write))
            {
                using(StreamWriter streamWriter = new StreamWriter(cryptoStream))
                {
                    streamWriter.Write(data);
                }
            }
        }
        return memoryStream.ToArray();
    }
}

警告7 CA2202:Microsoft.Usage:对象'cryptoStream'可以在方法'CryptoServices.Encrypt(string,byte [],byte [])'中多次处理.为避免生成System.ObjectDisposedException,不应在对象上多次调用Dispose:Lines:34

警告8 CA2202:Microsoft.Usage:对象'memoryStream'可以在方法'CryptoServices.Encrypt(string,byte [],byte [])'中多次处理.为避免生成System.ObjectDisposedException,不应在对象上多次调用Dispose:Lines:34,37

您需要Visual Studio代码分析才能看到这些警告(这些不是c#编译器警告).
