Stream流转MemoryStream流以及输出字符串的方式

        public MemoryStream StreamToMemoryStream(Stream instream)
        {
            MemoryStream outstream = new MemoryStream();
            const int bufferLen = 4096;
            byte[] buffer = new byte[1024 * 1024 * 5];
            int count = 0;
            while ((count = instream.Read(buffer, 0, bufferLen)) > 0)//Read和Write会偏移所以offset不需要变
            {
                outstream.Write(buffer, 0, count);
            }
            return outstream;
        }
            //调用方法
            //MemoryStream ms = StreamToMemoryStream(stream);
            //byte[] b = ms.ToArray();
            //string s = Encoding.UTF8.GetString(b, 0, b.Length);
            //return s;
