XMLDocument vs XDocument vs XmlReader vs LINQ to Xml [英] XMLDocument vs XDocument vs XmlReader vs LINQ to Xml

问题描述

我正在为我的项目编写一个应用程序，其中必须使用C＃解析XML文档。所以它是这样的：



第一档：

I was writing an application for my Project in which XML documents have to be parsed using C#. So it was something like that:

1st file:

<name> Name of Student </name>
              <class> ClassofStudent </class>

依旧..



第二档：



< monday>

and so on..

2nd file :

<monday>

<period1>C++</period1>
                       <period2>Maths</period2>

等等onnn



和他们的5个文件更像他们。事情是，只有一个文件包含大量元素（它是一个整月的出勤记录），而其他都很简短。



我只是谷歌搜索所有内容，发现有不同的方法来解析C＃中的XML，但有些方面存在高内存消耗或相对较低的速度等问题。



我无法做出决定的事情是我应该使用上述哪一项（XMLDocument或XDocument或XmlReader或LINQ to Xml）



或者我的目的是n不是那么高，所以我选择使用它并不重要吗？

我更喜欢Styling ==性能，因为我必须稍后设置它们（GUI）。哪一个将是更容易实现。

谢谢

and so onnn

and their are 5 files more like them.The thing is that only one of the file contains a huge number of elements ( its a kind of attendance record for whole month) while others are short.

I was just googling everything and found out there are different methods to parse XML in C#, but some face issues like high memory consumption or relative less speed.

The matter that i am unable to make decision is which of the above should i use (XMLDocument or XDocument or XmlReader or LINQ to Xml )

Or as my purpose will not be that much high , so it will not matter me what i choose to use?
I prefer Styling== performance , as i have to later style them also(GUI).And which one will be easier to implement too.
Thankyou

推荐答案

这一切都取决于许多不同的因素。最简单的是 XMLDocument 或 XDocument （取决于你的任务，我也怀疑没有LINQ to XML的XDocument 会得到回报，所以考虑使用LINQ，但是 XmlReader / XmlWriter 可以获得最佳性能。请参阅我对这些方法的简短回顾：

It all depends on a number of different factors. The easiest would be XMLDocument or XDocument (depending on your tasks, also, I would doubt that XDocument without LINQ to XML would pay off, so consider using LINQ with that), but XmlReader/XmlWriter can get you top performance. Please see my short review of those approaches:

1. 使用 System.Xml.XmlDocument 类。它实现了DOM接口;如果文档的大小不是太大，这种方式是最简单和最好的。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx [ ^ ]。
2. 使用类 System.Xml.XmlTextWriter 和 System.Xml.XmlTextReader ;这是最快的阅读方式，特别是你需要跳过一些数据。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmlwriter.aspx [ ^ ]， http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx [ ^ ]。
3. 使用类系统.Xml.Linq.XDocument ;这是类似于 XmlDocument 的最合适的方式，支持LINQ to XML Programming。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx [ ^ ]，http://msdn.microsoft.com/en-us/library/bb387063.aspx [ ^ ]。

1. Use System.Xml.XmlDocument class. It implements DOM interface; this way is the easiest and good enough if the size if the document is not too big.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^].
2. Use the classes System.Xml.XmlTextWriter and System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmlwriter.aspx[^], http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx[^].
3. Use the class System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^], http://msdn.microsoft.com/en-us/library/bb387063.aspx[^].
