保存数据结构在C＃ [英] Saving Data Structures in C#

问题描述

我写一个家庭图书馆管理者学习C＃。

I'm learning C# by writing a home library manager.

我将书存放在一个数据结构，并对其执行操作的BookController的。

I have a BookController that will store the books in a data structure and perform operations on them.

C＃有在字典中的数据保存到本地文件也许是在一个XML时尚的一种方式后加载，还是我将不得不写自己？

Does C# have a way of saving the data in the dictionary to a local file perhaps in an XML fashion to load later, or am I going to have to write it myself?

什么是保存和加载提供给C＃这个数据的最好的方法？只是需要指出的好的方向发展。

What is the best method of saving and loading this data available to C#? Just need pointed in a good direction.

推荐答案

事实上，C＃（语言）不知道的任何关于serailization，但.NET（框架）提供了很多方法... 的XmlSerializer ，的BinaryFormatter ，的DataContractSerializer （.NET 3.0） - 或有一些定制的序列化框架太

Actually, C# (the language) doesn't know anything about serailization, but .NET (the framework) provides lots of ways... XmlSerializer, BinaryFormatter, DataContractSerializer (.NET 3.0) - or there are a few bespoke serialization frameworks too.

要使用哪一个取决于你要求; 的BinaryFormatter 使用简单，但烧伤集元数据信息存入文件 - 使之成为非便携式（你不能在Java中打开它，例如）。 的XmlSerializer 和的DataContractSerializer 主要是基于XML的，使得它非常便携，但相当大，除非你压缩。

Which to use depends on your requirements; BinaryFormatter is simple to use, but burns assembly metadata information into the file - making it non-portable (you couldn't open it in Java, for example). XmlSerializer and DataContractSerializer are primarily xml-based, making it quite portable, but fairly large unless you compress it.

一些专有的序列化两者之间中途; protobuf网是一个二进制格式化（所以非常密集的数据），但它遵循用于数据的便携式标准格式（谷歌的协议缓冲区SPEC）。无论这是非常有用取决于您的方案

Some proprietary serializers are half-way between the two; protobuf-net is a binary formatter (so very dense data), but which follows a portable standard for the data format (Google's protocol buffers spec). Whether this is useful depends on your scenario.

典型的编码（这里使用的XmlSerializer ）：

Typical code (here using XmlSerializer):

        XmlSerializer ser = new XmlSerializer(typeof(Foo));
        // write
        using (var stream = File.Create("foo.xml"))
        {
            ser.Serialize(stream, foo); // your instance
        }
        // read
        using (var stream = File.OpenRead("foo.xml"))
        {
            Foo newFoo = (Foo)ser.Deserialize(stream);
        }
