This article is to share with you about Linq how to achieve XML conversion, the editor feels very practical, so share with you to learn, I hope you can get something after reading this article, say no more, follow the editor to have a look.

When learning Linq, we often encounter the problem of Linq implementing XML transformation. Here we will introduce the solution to the problem of Linq implementing XML transformation.

Linq implements XML conversion, converting objects in memory to XML

With LINQ queries, you can easily convert data between in-memory data structures, SQL databases, ADO.NET datasets, and XML streams or documents. The following example is that Linq implements a XML transformation that converts objects in in-memory data structures into XML elements.

Class XMLTransform

{

Static void Main ()

{

/ / Create the data source by using a collection initializer.

List students = new List ()

{

New Student {First= "Svetlana", Last= "Omelchenko", ID=111

Scores = new List {97,92,81,60}}

New Student {First= "Claire", Last= "O'Donnell", ID=112

Scores = new List {75,84,91,39}}

New Student {First= "Sven", Last= "Mortensen", ID=113

Scores = new List {88,94,65,91}}

}

/ / Create the query.

Var studentsToXML = new XElement ("Root"

From student in students

Let x = String.Format ("{0}, {1}, {2}, {3}", student.Scores [0]

Student.Scores [1], student.Scores [2], student.Scores [3])

Select new XElement ("student"

New XElement ("First", student.First)

New XElement ("Last", student.Last)

New XElement ("Scores", x)

) / / end "student"

); / / end "Root"

/ / Execute the query.

Console.WriteLine (studentsToXML)

/ / Keep the console open in debug mode.

Console.WriteLine ("Press any key to exit.")

Console.ReadKey ()

}

}

Linq implements the XML transformation, and this code generates the following XML output:

Svetlana Omelchenko 97 Claire O'Donnell 92 81 Claire O'Donnell 39 Sven Mortensen 88 91 is how Linq achieves XML conversion. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article.
