PGP PgpPublicKeyEncryptedData抛出PartialInputStream中的流的过早结束

Question

我已经在Java上看到了几个有关关闭流的线程。我只是不明白他们在做什么。一旦发现问题，我将再次将所有内容转换为uses。

是否可能因为我将私钥存储为字符串然后进行了转换？

        public static MemoryStream StringToStream(string toConvert)
    {
        // convert string to stream
        var byteArray = Encoding.Default.GetBytes(toConvert);
        //byte[] byteArray = Encoding.ASCII.GetBytes(contents);
        var stream = new MemoryStream(byteArray);

        return stream;
    }

我打算对此做一些改进，但是当我无法正常使用时，我基本上回到了此处发布的版本Original Post

public static byte[] DecryptBytes(byte[] inputData)
    {
        if(!PrivateKeyPopulated)
        { throw new Exception("PrivateKey Must be populated!!!");}

        if (String.IsNullOrWhiteSpace(_passcode))
        { throw new Exception("Passcode Must be populated!!!"); }

        byte[] error = Encoding.ASCII.GetBytes("ERROR");

        Stream inputStream = new MemoryStream(inputData);
        inputStream = PgpUtilities.GetDecoderStream(inputStream);
        MemoryStream decoded = new MemoryStream();

            PgpObjectFactory pgpF = new PgpObjectFactory(inputStream);
            PgpEncryptedDataList enc;
            PgpObject o = pgpF.NextPgpObject();

            //
            // the first object might be a PGP marker packet.
            //
            if (o is PgpEncryptedDataList)
                enc = (PgpEncryptedDataList)o;
