An example of how to use LINQ in C#

The following example shows how to run a LINQ query.

Code:

using System;
using System.Linq;

namespace ConsoleApplications
{
    class TestLinqInCSharp
    {
        static void Main(string[] args)
        {
            string[] customers = {   "Arianne",
                                     "Bill", 
                                     "David", 
                                     "Manuel", 
                                     "Veronic", 
                                     "Asia", 
                                     "Daniel", 
                                     "Renate", 
                                     "Vincent", 
                                     "Alexia", 
                                     "Daisy"};

            var nameQuery =
                from name in customers
                where (name.StartsWith("A"))
                select name;

            foreach (string n in nameQuery)
            Console.WriteLine("{0}", n);
        }
    }
}

Result:

Arianne
Asia
Alexia

In this example there are three basic parts to every LINQ query:

1. Get the data source.
2. Create the query.
3. Execute the query.
