List<Customer> customers = new List<Customer>();
customers.Add(new Customer { Id = 1, Name = "John Hammond", Country = "United States" });
customers.Add(new Customer { Id = 2, Name = "Mudassar Khan", Country = "India" });
customers.Add(new Customer { Id = 3, Name = "Suzanne Mathews", Country = "France" });
customers.Add(new Customer { Id = 4, Name = "Robert Schidner", Country = "Russia" });
if (!string.IsNullOrEmpty(customer.Name))
{
customers = customers.Where(x => x.Name.StartsWith(customer.Name)).ToList();
}
return customers;
