Subhajit - Create a console application and create a customer class
public class Customer
{
public int CustomerCode { get; set; }
public string CustomerName { get; set; }
public int TotalOrder { get; set; }
}
2. Create a list of customers
var customerList = new List<Customer>()
{
new Customer{CustomerCode=101,CustomerName = "Steve", TotalOrder = 2, CountryCode="US"},
new Customer{CustomerCode=102,CustomerName = "Mark", TotalOrder = 4, CountryCode="IN"},
new Customer{CustomerCode=103,CustomerName = "Bill", TotalOrder = 7, CountryCode="US"},
new Customer{CustomerCode=104,CustomerName = "Dell",TotalOrder = 6, CountryCode="US"}
};
3. Now we are going to select the distinct country code from the list
var result = countryList.Select(x=> x.CountryCode).Distinct().ToList();
