Remove object from array in List

Question

I have a list of Customers, and each customer can have multiple orders, however I need to delete some of the orders from customers. If I loop through the list, I can find the Orders that I need to delete, but how do I actually delete them?

List<Customers>

public class Customers
{
    public int CustomerId { get; set; }
    public string NameFirst { get; set; }
    public Order[] Orders { get; set; }
}

public class Orders
{
    public string OrderMode { get; set; }
    public int Id { get; set; }
}

Just a semantic remark: rename your class to Customer. A class represents a single object and should have a singular noun. Except for a collection-class (Customers would be a class representing a collection of customers). Same goes for your Order-class. — Abbas

You should use List<Order> instead of an Order[] array:

public class Customers
{
    public int CustomerId { get; set; }
    public string NameFirst { get; set; }
    public List<Order> Orders { get; set; }
}

Then do the following:

customer.Orders.RemoveAll(x => x.OrderMode == "SomeOrder");

use list collection instead of array (you can't remove item in array)

        YouList.Remove (Orders);

or YouList.RemoveAt(index)

Arrays do not have a Remove, nor a RemoveAt method.
