How to use brackets to define scope
In the past especially in unit-test code I've found myself creating variables such as **customer1**, **customer2**, **customer3** in one method since it was all the same scope. Just discovered that you can use brackets like this to create scope so that you can use the same variable repeatedly.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace TestScope8383
{
    class Program
    {
        static void Main(string[] args)
        {
            TheTest tt = new TheTest();
        }
    }

    public class TheTest
    {
        List<Customer> customers = new List<Customer>();

        public TheTest()
        {
            {
                Customer customer = new Customer { LastName = "Smith" };
                customers.Add(customer);
            }
            {
                Customer customer = new Customer { LastName = "Thompson" };
                customers.Add(customer);
            }

            customers.ForEach(c => Console.WriteLine(c.LastName));
            Console.ReadLine();
        }
    }
    public class Customer
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Street { get; set; }
        public string Location { get; set; }
        public string ZipCode { get; set; }

    }
}
Loren Andrus: Or, you could simply re-use the variable. (I don't understand why it seems so important to repeatedly create new variables with the same name. Apparently the example presented here is an artificially small sample to demonstrate the ability.)

Thus:

public TheTest()
{
     Customer customer = new Customer { LastName = "Smith" };
     customers.Add(customer);
     customer = new Customer { LastName = "Thompson" };
     customers.Add(customer);

     customers.ForEach(c => Console.WriteLine(c.LastName));
     Console.ReadLine();
}


Though, honestly, if I'm not doing anything else with the objects before dumping them into the list (or whatever), I don't even declare a variable for them.
need markup?
