Select custom collections using LINQ in Console Application.

Here we have an example to select custom data using LINQ. 

Previous Blog:

Create XML result from database using LINQ.

We have a customer information and we will select it using LINQ.

class Program

    {

        static void Main(string[] args)

        {

            CustomData(); 

        }

        public static void CustomData()

        {

            var results = from m in LoadCustomData()

                                    select m;

            foreach (CustomerInfo item in results)

            {

         Console.WriteLine("Name:{0},Address:{1},Mobile:{2}",item.Name,item.Address,item.Mobile);            

            }

            Console.ReadKey();

        }

        public static List<CustomerInfo> LoadCustomData()

        {

            List<CustomerInfo> customer = new List<CustomerInfo>();

            customer.Add(new CustomerInfo { Name = "Ashraf", Address = "Delhi", Mobile = "8789789" });

            customer.Add(new CustomerInfo { Name = "Sheikh", Address = "Noida", Mobile = "567778" });

            customer.Add(new CustomerInfo { Name = "Sachin", Address = "Bangalore", Mobile = "57676787" });

            customer.Add(new CustomerInfo { Name = "Sunil", Address = "Mysore", Mobile = "788789908" });

            return customer;

        }

}

Created a class for Customer Information:

 public class CustomerInfo
    {
        public string Name { get; set; }
        public string Address { get; set; }
        public string Mobile { get; set; }
    }

Snaps:
