Basic Query Operations EXAMPLES

1. Selecting Data   
//data source
  int[] numbers = { 2, 4, 1, 3, 5, 34, 67, 89, 90, 50 };

lShow.Text += "<br><br><b> Numbers Are</b><br>";
//query expression
var qry1 = from n in numbers
                   select n;
//executing
foreach (var data in qry1)
{
     lShow.Text += "<br>" + data;
}

2. Filtering Data  
To display all nos between 10 and 50.
//data source
  int[] numbers = { 2, 4, 1, 3, 5, 34, 67, 89, 90, 50 };

 lwhere.Text+= "<br><br><b> Numbers Are</b><br>";
//query expression
var qry1 = from n in numbers
                   where n>10 && n<50
                   select n;
//executing
foreach (var data in qry1)
 {
     lwhere.Text += "<br>" + data;
}
