In this post I would like to show on how to create a xml document on the fly and save it on a file in our local disk.

I will use Visual Studio 2010 Ultimate edition and C# as the development language. Visual Studio 2010/2008 express editions will suffice.  


1) Fire VS and create a web site. Choose an appropriate name for your site.

2) In the code behind file Default.aspx.cs, add the namespace

using System.Xml.Linq;

All the classes we need to manipulate XML documents are inside this namespace.

In this sixth example we want to find the the information of the second element.

3) In the Page_Load  event handling routine of the default.aspx.cs file, type the following


XDocument xDoc = new XDocument(
            new XDeclaration("1.0", "UTF-8", null),
            new XElement( "Students",
                new XElement("Student",
                    new XComment("We only have 3 elements"),
                    new XElement("StudentId", "5"),
                    new XElement("Name", "Lewis"),
                    new XElement("Sex", "Male")
                    )));
 
            xDoc.Save("C:\\test\\student.xml");
            Response.Write("Saved");
 
We use the XDocument class to represent an xml document. Then we create a new XML declaration (XDeclaration) and after that we do create XML elements (XElement) with the appropriate content.
Finally we use the Save method of the XDocument object, to save the newly created file in the local filesystem.
Email me if you need the source code. Hope its helps !!!!
