使用SharpZipLib压缩序列化对象

如题

测试代码如下：

string str_org = "aaaaaaaaaabbbbbbbbbbbbcccccccccdddddddd";            System.IO.MemoryStream m = new System.IO.MemoryStream(System.Text.Encoding.ASCII.GetBytes(str_org));            m.Position = 0;            System.IO.MemoryStream zip;            QouShui.DLL.Message.Serializes.Serialize(m, out zip);            Console.WriteLine(m.Length);            Console.WriteLine(zip.Length);            object o;            zip.Position = 0;            QouShui.DLL.Message.Serializes.DeSerialize(zip, out  o);            Console.WriteLine(System.Text.Encoding.ASCII.GetString( (o as System.IO.MemoryStream).ToArray()));
