什么是对象序列化和反序列化?

序列化与普通技术(例如读取对象的属性，然后用它们填充DataRow的列并最终将DataRow保存在DB中)有什么区别?

解决方案

串行化通常是指创建可用于存储(也许在文件中)的数据(而不是对象)的版本，以便通过网络，或者仅用于在单台计算机上的进程/AppDomain/etc之间进行传输.

串行化通常意味着将数据写为字符串(例如:xml/json)或原始二进制文件(byte[]等).反序列化是相反的过程.提取原始数据(从文件，传入的网络套接字等)并重建对象模型.

使用db的区别在于它没有固有的表格布局，也没有与数据库的真正联系.数据可以是任何形状，并且更倾向于映射到面向对象的布局，而不是映射到表的行/列性质.

大多数平台都有一系列的序列化工具.例如，听起来您在谈论.NET，因此BinaryFormatter(特定于.NET)，XmlSerializer，DataContractSerializer，Json.NET和protobuf-net/dotnet-protobufs都符合条件.

What are object serialization and deserialization?

What difference does serialization have with normal techniques like reading an object's properties and then filling a DataRow's columns with them and finally saving the DataRow in DB?

解决方案

Serialization generally refers to creating a version of the data (rather than the objects) that can be used for storage (perhaps in a file), for transfer over a network, or perhaps just for transfer between processes / AppDomains /etc on a single machine.

Serialization typically means writing the data as a string (think: xml / json) or as raw binary (a byte[] etc). Deserialization is the reverse process; taking the raw data (from a file, from an incoming network socket, etc) and reconstructing the object model.

The difference between using a db is that it has no intrinsic tabular layout, and no real tie to a database; the data can be any shape, and tends to map more closely to the object-oriented layout than to the rows/columns nature of tables.

Most platforms have a range of serialization tools. For example, it sounds like you're talking about .NET - so BinaryFormatter (.NET-specific), XmlSerializer, DataContractSerializer, Json.NET and protobuf-net / dotnet-protobufs would all qualify.
