ASp.Net LINQ array search

Here I have used LINQ query to search Array. Using LINQ I have checked if length of array element is greater than or equal to 5 then it will display. LINQ query you can use in array in other parpuse also, for example searching from array and array sorting.

Step 1)Copy and paste below code.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Collections;

using System.Xml.Linq;

public partial class _Default : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

        string fname="";

        string[] instructors = { "Aaron", "Fritz", "Keith", "Scott" ,"sourav"};

        IEnumerable<string> query = from n in instructors

                                    where n.Length >= 5

                                    orderby n ascending

                                    select n;

        foreach (string name in query)

        {

            fname = fname +"<br>"+ name;

        } 

        this.Label1.Text = fname;

    }

}
