Subhajit - Create a console application and create a customer class in it.
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},
new Customer{CustomerCode=102,CustomerName = "Mark", TotalOrder = 4},
new Customer{CustomerCode=103,CustomerName = "Bill", TotalOrder = 7},
new Customer{CustomerCode=104,CustomerName = "Dell",TotalOrder = 6}
};
3. Now with the help of substring in the lambda expression we will be able to get the 1st two letters for each customers.
var result = customerList.Select(a => a.CustomerName.Substring(0,2)).ToList();
foreach (var a in result)
{
Console.WriteLine(a.ToString());
}
Console.ReadLine();
