XMLDocument vs XDocument vs XmlReader vs LINQ to Xml

Question

0.00/5 (No votes)

See more:

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:

XML

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

and so on..

2nd file :

<monday>

XML

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

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

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:

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[^].
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[^].
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[^].
