This article introduces the relevant knowledge of "what are the LINQ To XML classes?". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

What is LINQ To XML?

LINQ to XML is a LINQ-enabled in-memory XML programming interface that allows you to process XML in the .NET Framework programming language.

It places XML documents in memory, much like the document object Model (DOM). You can query and modify the XML document, and after modifying it, you can save it as a file, or you can serialize it and send it over the network. However, LINQ to XML is different from DOM: it provides a new object model, which is lighter and easier to use, which takes advantage of the language improvements of Visual C # 2008.

The most important advantage of LINQ to XML is its integration with Language-Integrated Query (LINQ). Because of this integration, queries can be written against in-memory XML documents to retrieve collections of elements and attributes. LINQ to XML's query capabilities are functionally (though not syntactically) comparable to XPath and XQuery. Visual C # 2008 integrates with LINQ to provide stronger typing, compile-time checking, and improved debugger support.

What is the LINQ To XML class

The LINQ To XML class is located under the System.Xml.Linq namespace.

Here are 18 commonly used classes

1.XAttribute represents a XML attribute.

2.XCData represents a CDATA text node.

3.XComment represents an XML comment.

4.XContainer is an abstract base class that applies to all nodes that may have child nodes. The following class is derived from the XContainer class:

◆ XElement

◆ Xdocument

5.XDeclaration represents a XML declaration. The XML declaration is used to declare the XML version and the encoding of the document. In addition, the XML declaration specifies whether the XML document is a stand-alone document.

6.XDocument represents an XML document.

7.XDocumentType represents an XML document type definition (DTD).

8.XElement represents a XML element.

9.XName represents the name of the element (XElement) and attribute (XAttribute).

10.XNamespace represents the namespace of XElement or XAttribute. Namespaces are a component of XName.

11.XNode is an abstract class that represents the nodes of the XML tree. The following class is derived from the XNode class:

◆ XText

◆ XContainer

◆ XComment

◆ XProcessingInstruction

◆ XDocumentType

12.XNodeDocumentOrderComparer provides the ability to compare the document order of nodes.

13.XNodeEqualityComparer provides the ability to compare whether the values of nodes are equal.

14.XObject is the abstract base class for XNode and XAttribute. It provides annotations and event capabilities.

15.XObjectChange specifies the type of event when an event is raised on a XObject.

16.XObjectChangeEventArgs provides data for Changing and Changed events.

17.XProcessingInstruction represents a XML processing instruction. Processing instructions pass information to the application that processes the XML.

18.XText represents a text node. You don't have to use this class in most cases. This class is mainly used to mix content.
