what this code under RijndaelManaged means?
<p>I just want to know what this codes means? I have tried to put it in C# compiler but it does not work.</p>

<pre><code>    private byte[] Method_05(string A_0, string A_1)
{
    RijndaelManaged managed = new RijndaelManaged {
        Key = Convert.FromBase64String(A_0),
        IV = Convert.FromBase64String(A_1)
    };strong text
    Stream manifestResourceStream = base.GetType().Assembly.GetManifestResourceStream("s.Assembly");
    CryptoStream stream2 = new CryptoStream(manifestResourceStream, managed.CreateDecryptor(), CryptoStreamMode.Read);
    byte[] buffer = new byte[manifestResourceStream.Length];
    stream2.Read(buffer, 0, buffer.Length);
    stream2.Close();
    manifestResourceStream.Close();
    return buffer;
}
</code></pre>

<p>exactly here : </p>

<pre><code>Stream manifestResourceStream = base.GetType().Assembly.GetManifestResourceStream("s.Assembly");
CryptoStream stream2 = new CryptoStream(manifestResourceStream, managed.CreateDecryptor(), CryptoStreamMode.Read);
byte[] buffer = new byte[manifestResourceStream.Length];
stream2.Read(buffer, 0, buffer.Length);
stream2.Close();
manifestResourceStream.Close();
return buffer;
