Question

我用以下代码压缩我的字符串：

            //prepare
            byte[] byteArray = Encoding.ASCII.GetBytes(txt);
            MemoryStream stream = new MemoryStream(byteArray);
            MemoryStream outStream = new MemoryStream();
            //compress
            BZip2.Compress(stream, outStream, false, 9);
            //stringify
            var reader = new StreamReader(outStream);
            reader.BaseStream.Seek(0, SeekOrigin.Begin);
            var str = reader.ReadToEnd();

如果我尝试对该字符串进行解压缩，则到达那里的Decompress方法将抛出EndOfStreamException

            var compressedBytes = Encoding.ASCII.GetBytes(str);
            var compressedStream = new MemoryStream(compressedBytes);
            compressedStream.Seek(0, SeekOrigin.Begin);

            MemoryStream decompressedStream = new MemoryStream((int)compressedStream.Length);

            BZip2.Decompress(compressedStream, decompressedStream, false);

如果有人更了解此lib，以下是以下堆栈跟踪信息，这可能会有所帮助

有人建议问题可能在哪里吗？
