Here is example for this.
In this example we take one DataTable object which contains two columns 'product_id' and 'product_name'. This DataTable has many rows. Now we want to convert DataTable object into list of class object. We have one Class 'clsProduct' which has two property 'product_id' and 'product_name'. Now we transform DataTable object data in to list of clsProduct class object using LINQ.
