Linq Projection in C#

In this tutorial we will look at LINQ Projection, which is when we can select specific data from a source without retrieving all fields. We will be creating a class to define a list in which we will create a number of people with IDs, names and cities. Then we will use buttons to select only parts of this data.

First, we will start off by creating a new Windows Form application in VS.NET 2008. Next, we will create a class – call it aList – and define our list object:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace LINQProjection_cs
{
class aList
{
private int _personID;
private string _name;
private string _city;
