对象序列化与反序列化（二进制 byte[]）

1.序列化 
public static byte[] SerializeObject(object obj)
        {
            if (obj == null)
                return null;
            MemoryStream ms = new MemoryStream();
            BinaryFormatter formatter = new BinaryFormatter();
            formatter.Serialize(ms, obj);
            ms.Position = 0;
            byte[] bytes = new byte[ms.Length];
            ms.Read(bytes, 0, bytes.Length);
            ms.Close();
            return bytes;
        }

string objectString=System.Convert.ToBase64String(SerializeObject(importedObj));

2.反序列化
   public static object DeserializeObject(byte[] bytes)
        {
            object obj = null;
            if (bytes == null)
                return obj;
            MemoryStream ms = new MemoryStream(bytes);
            ms.Position = 0;
            BinaryFormatter formatter = new BinaryFormatter();
            obj = formatter.Deserialize(ms);
            ms.Close();
            return obj;
        }
