Create a xml file using LINQ:

Using the classes from the System.Xml.Linq namespace and the features available in .NET 3.5, constructing an XML document is very easy and very readable.

Constructing a document in this way is possible because of the functional construction feature in LINQ to XML. Functional construction is simply a means of creating an entire document tree in a single statement.

namespace LINQContext
{
    class Program
    {
        static void Main(string[] args)
        {
            var data = getDataSource().ToArray();
            XElement element = new XElement("Employees", from emp in data select 
 new XElement("Employee",
                   new XElement("EmpID",emp.EmpNo),
                   new XElement("EmpName",emp.EmpName),
                   new XElement("Address",emp.EmpAddress)));
            element.Save("Data.xml");
            Console.WriteLine(element);
            Console.ReadLine();
        }

        public static List<Emp> getDataSource()
        {
          List<Emp> collection = new List<Emp>();
          collection.Add(new Emp { EmpNo = 123, EmpName = "Sunil", 
EmpAddress = "Delhi" });
            collection.Add(new Emp { EmpNo = 124, EmpName = "syam", EmpAddress = " Delhi " });
            collection.Add(new Emp { EmpNo = 125, EmpName = "ranjit", EmpAddress = " Delhi " });
            collection.Add(new Emp { EmpNo = 126, EmpName = "anil", EmpAddress = " Delhi " });
            collection.Add(new Emp { EmpNo = 127, EmpName = "jiju", EmpAddress = " Delhi " });
            collection.Add(new Emp { EmpNo = 128, EmpName = "anil", EmpAddress = " Delhi " });
            collection.Add(new Emp { EmpNo = 129, EmpName = "syam", EmpAddress = " Delhi " });
            collection.Add(new Emp { EmpNo = 130, EmpName = "ranjit", EmpAddress = " Delhi " });
            return collection;
            
        }
    }
    partial class Emp
    {
        public int EmpNo
        {
            get;set;
        }
        public string EmpName
        {
            get;set;
        }
        public string EmpAddress
        {
            get;set;
        }

    }
