Substring in lambda C#

Lambda

Substring in lambda C#

  1. 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();
