LINQ Sample

There are three parts in any LINQ Query
a. Data Source  - Could be an array collection, Database TAble, Object Collection, Etc...
b. Creating Query - The LINQ Query Creation
c. Executing Query - Query created doesn't get executed immedietly. It gets executed only during enumeraing the result

Sample

class SampleLINQ
{       
    static void Main()
    {
        //  1. Getting Data source.
        int[] intarray = new int[5] { 3, 1, 9, 63, 17};
        // 2. Query creation.
        var intenumQuery =
            from num in intarray
            where (num % 3) == 0
            select num;
        // 3. Query execution.
        foreach (int intvalue in intenumQuery )
        {
            Console.Write("{0,1} ", num);
        }
    }
}
